The nozzle on the angle grinder to cut metal tiles

Is it possible to cut metal tiles with an angle grinder

To put on a roof of metal is simple, it can even a person who is far from construction. The important question of what to cut the tile, the master arises when trying to cut the material. This roofing profile sheet metal is now the most profitable in terms of price / quality. Let’s talk about how to process it.

Cutting metal is difficult because its surface is not horizontal-even, and undulating. At the industrial level, expensive high-performance tools are used. But with what can cut metal tiles for the average builder who has decided, for example, to repair the roof at the cottage?

nozzle, angle, grinder, metal, tiles

There are several ways and tools to do this work:

  • Cutting with scissors for metal;
  • Cutting with a jigsaw;
  • The use of a circular saw;
  • angle grinder;
  • A drill with an attachment;
  • electric notching scissors.

Let’s consider all the presented options in more detail, starting with the most popular:

Metal scissors

If the construction site is small, and there is not much to cut, you can use the usual and customary scissors for metal. But it is worth setting yourself up in advance that the work will be time consuming.

Scissors cope well with a thin sheet, but the master has to make a great effort. The hand gets tired quickly. In order not to hurt yourself, you have to bend one already cut edge upwards. In addition, the “wave” scissors crumple and deform the metal.

The advantage in using such a tool is the already voiced simplicity, low cost and a good not burnt end face. It’s easy and safe to cut metal right on the roof.

Work with an electric jigsaw for metal is only slightly easier than with scissors. It badly takes the edges, bends them, so it is recommended to make a small pre-cutting with scissors.

In areas where the sheet makes a wave, jigsaw because of the reciprocating motion unbends a little roughness, especially on short blanks, so after sawing the length of the edges may increase, which prevents the proper assembly of the roof, especially the valley.

Before you cut metal tiles with a jigsaw, you need to choose a saw with a length to spare for the height of the wave. If its movements are limited to a range of 2 cm, and the height of the wave on the sheet is 4-6 cm, then the length of the saw with the attachment should be at least 10-11 cm.

To avoid damaging the surface of the sheet, not to tear off the paint in the incision places, we recommend to buy an electric jigsaw with rubberized guideways. You can glue the soft strips yourself by cutting them from an ordinary medical adhesive tape.

Circular saw

A manual circular saw is the best tool for cutting metal tile, according to many builders. The work is performed literally in seconds, the metal edges are smooth and do not overheat. The best results happen when the metal tile cutting disc is used pobedite universal.

These tools always live up to expectations, but each has its own disadvantages and advantages:

It is clear that with all the excellent performance, the circular saw, especially with a pobeditovy disk, not all masters can afford. For a simple small gable roof does not require diagonal cuts, which means you can get by with well-sharpened metal scissors.

Cutting metal tile angle grinder. pros and cons

Manufacturer of metal tile officially banned to cut it with an angle grinder. Despite this, many private builders continue to use a common household tool. It’s a pity to spend money on something else, if you already have a more or less suitable device.

An angle grinder cuts just like a circular saw, quickly and easily. Why do professional builders and manufacturers of this roofing material so protest against its use? And whether you can cut a metal tile angle grinder?

  • Ripped metal edges oxidize and rust in future use.
  • The metal is strongly heated, deformed and corroded at the ends.
  • Italian expensive tiles with plastic coating is sold with a written warranty of 15 years. If the experts identify the use of angle grinder for cutting it, the warranty is lost.
  • an angle grinder is dangerous to use on a roof.
  • When you perform metal cutting angle grinder, a lot of small metal filings fly off, which will eventually rust and spoil the appearance of the roof.
  • You can burn the installed waterproofing and the moisture will seep to the purlins.

Those masters who do not want to or can not give up cutting angle grinder, you can advise a proven combined method. Metal slices are cut with an angle grinder, adding to the desired size of 1-2 cm, and then the melted edge is cut to size with scissors for metal.

In this case, the quality does not suffer, no need to buy or rent another tool, but the labor intensity is doubled.

What kind of tool is needed for cutting metal roofing??

The whole complexity of this issue lies in the peculiarities of production of metal. The fact that after rolling roofing sheets are treated with a special varnish that serves as a special protective layer and prevents the appearance of rust. When cutting, it is necessary to take into account this peculiarity of the material. Any damage to this protection can lead to a reduction in service life. For this reason, only the following type of tool can be used for cutting:

  • Cut out scissors. They are designed to work on the inner side of the metal. Used to cut holes and other shapes on the template
  • Electric scissors. They are used for quick cutting of sheet metal, including metal tiles. Their advantage is their thin and clean cut, which saves on material consumption
  • Drill bit. Used for quick cutting of wave metal. Convenient enough for cutting round holes

The same tools should be used to cut other elements that are needed when installing metal. For example, they are suitable for mounting valley tiles. If you need to choose the most suitable tool should be carefully studied its technical characteristics and methods of application.

Features of the material

Metal tile is a profiled sheets of galvanized steel, which is applied a polymer coating that protects the material from rust and mechanical damage. The polymers used for the production of roofing (Pural, plastisol, polyester), have a sufficiently low melting point, so the use of abrasive tools for cutting metal is not recommended. The use of such devices causes the following consequences:

  • When the grinding disc at high speed polymer coating at the edges of the cut is melted, resulting in the surface of metal “spaces” unprotected metal.
  • When cutting tiles with abrasive tools at high speed cut edges are heated to a considerable temperature, due to which changed to the worse properties of steel, melted zinc layer.
  • After 1-2 years of operation the places where the polymer and zinc layer got damaged because of the use of abrasive tools for cutting, become s of corrosion, irreversibly destroying the structure of the material.

Pay attention! Handle, cut and mount the metal tile is allowed only with cold methods, ie, do not use a welding or grinder. It is better to order the sheets needed size than to cut the metal with abrasive tools, since after their use the factory warranty on the roof covering is removed.

Instruments for cutting metal tiles

Despite the fact that the sheet metal shingles appeared on the construction market for quite some time, not even professional builders have not yet come to a consensus on what tools can cut the product, and what categorically prohibited. So, cutting metal tiles. it’s quite a complicated issue. After all, from the wrong tools can affect the entire roofing system. The fact that in places of incision can be formed faintly visible chips, which later lead to the fact that the coating will lose its resistance to negative environmental factors. Also, you should know that there is a list of tools recommended by the manufacturer, and if it does not stick, then the warranty on the metal plate becomes invalid. Of course, you can always order cutting at the manufacturer’s equipment, but the cost of such work can significantly increase the entire budget, and in addition, not always can know in advance exactly what size you need those or other roofing elements. Therefore, it is much more efficient and economical to cut the product directly on site. What are the recommended tools for cutting metal?

In order not to damage the coating and preserve its protective layer, it is worth to cut the sheets correctly. First of all, you should avoid any deformation of the material, damage to the lacquer or polymer layer, the appearance of cracks on the surface of the decorative coating, as well as access sparks on the polymer, from which it can easily melt. The safest tools for working with metal would be the following:

Exactly the tools listed above perfectly cuts the metal tile and thus do not damage it. You can also note that this list is recommended by most manufacturers of metal shingles. As you can see, an angle grinder, or in other words, angle grinder, this list is not included. The fact that when cutting with abrasive disks is too high a probability of damaging the protective layers of roofing coating. Even subsequent painting can not protect the material from corrosion, and as a consequence, leaks. Since it is impossible to pick up exactly the same composition, as used by the manufacturer. Of course, when using an angle grinder, the work can be done in the shortest possible time, but the material is thereby subjected to significant changes. That is, when working angle grinder is a significant heat disk, which leads to the melting of decorative coating, steel, and zinc layer. As a result, we can say unequivocally that you can not cut the metal tile with an angle grinder, and should only use the tools recommended by the manufacturer.

How to cut a shingle of metal

To understand what tool to choose for cutting metal, it is worth to decide on the scheme of cutting. That is to know in advance whether it will be necessary to make many cuts or there will be a minimum of them. The greater the volume of work, the more powerful cutting equipment is needed. So, for example, to cut adjacency places it is enough to use hand scissors on metal, and to work with large sheets it is better to buy cutters, electric jigsaw or circular saw. When using a saw is recommended to use a special disk for cutting metal with teeth, that is, exclude abrasive circles. The main disadvantage of this tool is that they can only work on a solid and hard surface, which means that the tile at the place of installation will not work.

An alternative to the circular saw can be an electric jigsaw. It is a mobile tool, with which you can work even at height. However, it is worth bearing in mind that you will need to stock up on a large number of saws with fine teeth. Increased consumption is due to the fact that the teeth are very actively abraded by interaction with the metal. In addition, making curved cuts will be quite problematic. Another tool that is used by professionals. it’s cutting electric scissors. Such equipment is quite easy to cope even with geometrically complex cutouts and leaves no defects. They can be used directly on the roof and on the ground, but it is worth bearing in mind that this is a fairly expensive tool, which is recommended to purchase only in the case of a large volume of work.

A more affordable option can be the nozzle on the drill for cutting metal tiles, which is also called cricket. The principle of its work is similar to the notching scissors, that is, a special punch presses on the work area and as if nails or knocks out a move, resulting in a cut. The work requires a master a certain skill, so before you get to the main volume, it is worth practicing on a small section of metal, the calculation of metal on the roof.

To summarize, it can be noted that whatever tool has not been chosen, it is very important to ensure that no chips, cracks, scratches, scorch marks and other defects are formed on the sheets of shingles. If such areas still appear, it is worth to treat them with a special product or facade paint in the tone of the material. In addition, it is desirable to cut the product so that the place of the cut is hidden under other roofing elements, rather than in the open air.

How to cut a metal tile with metal scissors

Cutting with scissors for metal in their standard version is not available. This will require these types of devices:

The last option of equipment facilitates the task due to the power from the network, which speeds up the process and makes it less time-consuming.

Can you cut with an electric jigsaw

What else can be used to cut metal tiles? Technically it is possible to cut metal tiles with an electric jigsaw, but it is quite inconvenient. The jigsaw platform will not be able to adhere to the profiled surface of the sheet, and the cut will be uneven and jerky. In addition, you have to set the minimum cutting speed and swing amplitude of the pendulum so that the material does not overheat.

Electric jigsaw is justified in the absence of a special tool and the nozzle on the drill, with limited amount of work.

How to cut roofing tiles safely and correctly? To maintain the high corrosion resistant properties of the roofing material, the cutting should be done manually or with a specialized tool.

The best productivity and quality of cut gives the cutters with electric or pneumatic drive. With a limited amount of work will help a special attachment to the drill. Hand tool for cutting metal tiles is suitable for small amounts of cutting.

Alternative tools for cutting tiles

For cutting the metal sheets are placed on a horizontal plane. Under it in several places are padded bars of equal thickness. A line is drawn on the ruler with chalk or marker pen. Hold the sheet during cutting. To do this, put a wide board on it and move over it, cutting and pressing at the same time. At the end of the work should sweep away trash and sawdust from the sheet. After cutting, the places of splits, cuts, ends are treated with repair enamel of polymer coatings to protect against corrosion.

A wonderful nozzle on the drill for cutting metal tiles with the beautiful name “Cricket” easily copes with diagonal cutting sheets of the most complex texture. The attachment can be used to set the desired angle for convenient operation. It is easy to cut steel sheets up to 0.8 mm thick with this tool. Compared to a circular saw and even an angle grinder, a drill with an attachment will cost less.

The electric punching shears work on the same principle. The pivoting shank with pobedite tips cuts not the end face of the plate but the side face of the plate. These tools are good because they can cut out of the sheet metal most complex configurations.

All of these devices are good. But each is good in its own way. After comparing the pros and cons, you can choose the most appropriate tool in this particular case.

What and how to cut the metal. an overview of tools

Metal building materials are extremely convenient to use. They are highly flexible and malleable, while at the same time being distinguished by durability. Before you cut the metal tile, you need to learn the tools that can work and the basic rules of trimming this coating.

Before you start, you should study the structure of the sheet metal. It consists of several layers: a central layer and two side layers. The main is a thin sheet of cold-rolled steel. A layer of zinc is sprayed on it under high pressure. Depending on the type of metal tile. It can also be coated with various composites or polymers.

The question often arises why you can not cut a metal tile with an angle grinder. This tool can not work precisely because of the structure of the metal panel. The working part of the angle grinder is an abrasive disk rotating at a very high temperature. Because of this, the temperature rises significantly at the ends. Abrasive particles damage not only the upper coating of the tile, but also the inner panel. In addition, high temperatures melt zinc, which greatly reduces its resistance to aggressive external factors.

Consequently, it is possible to identify the following types of tools, which can not work when trimming shingles made of metal:

  • Any abrasive wheels;
  • Files or saws with spraying;
  • Hand saws for cutting metal (not used for shaped cuts).

The last tool in particular must be singled out. Often, craftsmen at home when cutting small sections of metal, use simple metal saws. But because of the toothed surface, they leave nicks on the coating, which in further use become a focus of corrosion.

In addition, all these devices somewhat deform the building material, changing not only its structure but also its shape. This is not acceptable when working on roofs of complex construction.

The steel disc

In theory, you can try to cut the metal tile with an angle grinder and a diamond disc, but you have to be more careful than when working with scissors.

  • You need to work at low speed to minimize the appearance of sparks and heating of the coating surface;
  • You need to cover all the tiles around. To do this, you can use metal sheets or profiled sheeting. Otherwise, individual sparks flying out from under the cutting surface will damage the structure of the roof;
  • Safety goggles and clothing must be worn.

Why not an angle grinder?

If you carefully read the instructions to the metal and its installation, then, of course, you will find a paragraph that says that the cutting angle grinder is prohibited. The warranty on the product in this case is simply invalidated. Why so?

Metal from above protected by a special polymer that does not tolerate high temperatures. And when using an angle grinder metal will be heated to just those critical temperatures, so that in certain places to melt and the zinc coating, and the polymer layer. The result. deformation of protective layers, such tiles will be damaged by rust and can even leak.

In addition, sparks from the contact of the abrasive disc and the tiles will fly in different directions, forming damage. These points will become small, and later more dangerous islands of corrosion.

Tip: If you decide to cut with an angle grinder, then try to shield the tile sheets from the sparks. And the places of cutting should be covered with paint for facades. This is not the best, but tolerable option.

The nozzle on the drill for cutting metal. cutters

Any man who likes to do everything with his hands has a drill in his kit. It is this simple device can cope with cutting metal tile, if you buy it as an accessory: a nozzle on the drill for cutting metal.

nozzle, angle, grinder, metal, tiles

In essence, it is a splint or punch, which, thanks to the matrix, pierces the metal with many repetitive movements. Through this, a strip is formed in the metal to be processed of the shape you need. The impact on the metal point, the maximum preservation of the integrity of the protective layers of metal. The width of the cut is 3.1 mm.

Such a nozzle is also called a chisel or notcher on metal. Of course it does not work like a pair of scissors, unlike electric scissors with two blades, but it does pierce.

The drill scissor nozzle is available on the market in several models from different manufacturers:

With the help of nozzle can be processed metals with the following parameters:

That is, the softer the substrate, the thicker it can be, so it can be cut with a drill with this attachment. In principle, all models of this nozzle work about the same parameters regarding the thickness of the metal, perhaps with some exceptions. The edge that forms the nozzle is not crumpled, but accurate and sharp. You only need to choose the right speed on the drive of the drill itself.

It is very convenient to cut rounded and any shaped cuts, using this mechanism, thanks to the punch. The same method you cut the venting accessories for the roof.

To work with the nozzle on the drill for cutting metal requires a little skill, but you will quickly learn it. The nozzle is attached to the chuck of the drill, which starts it in the work. Electro-mechanical shears also work in the same way.

What you can cut a metal tile for laying on the roof

When cutting metal tiles, there is a great risk of deformation of the sheet, melting the material from sparks. Damage to the protective polymer layer is particularly dangerous. Violation of its integrity leads to the appearance of rust and a significant reduction in life.

Overview of cutting tools

All of the tools that can be used to cut shingles are divided into two types:

  • manual (mechanical). only in private construction;
  • Electric. suitable for professional use for large amounts of work, the most convenient. battery-powered, with them it is easier to cut the metal directly on the roof.

Cutting tiles with an angle grinder (angle grinder) is impossible. The use of tools not included in the list of recommended by the manufacturer of the roofing material, leads to the removal of the warranty. Friction from the disk leads to the fact that the sheet is red-hot and begins to melt, the protective coating is burned. If it is not possible to use other tools, the cuts should be treated with corrosion-resistant paint.

If you have no experience, it is better to train on small remnants beforehand. The basic work must also be done with care. First make a cut, a little back from the markings, then trim.

The shavings must be removed in a timely manner when cutting shingles. It is recommended to cover the edges with a protective anticorrosive paint. On a sheet with a cut the next one is laid overlapping so as to exclude access of moisture.

Manual roofing shears for metal.

This cutting tool is one of the simplest, inexpensive tools for cutting along. It works like conventional scissors. Blades made of hardened steel. Available in three versions: left-hand, right-hand or straight cuts. They have comfortable handles that do not slip and provide good cutting force.

  • unsuitable for large quantities
  • The cutting force is needed;
  • blunted blades bend metal and get stuck in it;
  • there is a high risk of cutting on the edge of the sheet;
  • Difficulties when cutting across the wave.

For comfortable cutting, it is better to buy left and right scissors at the same time.

Manual nibbling (notching, punching) shears.

The main element is a cutting head with an open die for easy material entry and a chip cutter. Handle is shaped to fit comfortably in your hand. It has a soft-padded plastic cover to prevent slipping. Other ingredient is a transparent plastic chip protector that directs chips away, making for safer work.

The minimum cutting radius of slotted scissors is 25 mm. In order to start cutting, you drill a 8,5 mm hole in the sheet. Advantages. maneuverability, easy curved cuts.

Professional construction workers use electric shears. This tool has a powerful motor, it is easy to handle. Perfectly smooth, clean cut.

There are two types of electric shears: knife shears and slotted shears. The first it is convenient to cut metal tiles in a straight line, but it is difficult to perform a turn at an angle, slotted suitable for curved cuts. The main element consists of two blades, one of which is movable and the other is not. Chips are drained away, which prevents the appearance of defects on the protective polymer layer. Slotted shears have an open cutting head. The quality of cutting of this device is the best.

The most popular among professional builders involved in roof installation. Very easy to handle, working with electricity on the punch principle. Their main components are a movable punch and a stationary die. The die has a hole with the same shape as the punch.

Designed for quick cutting of sheet and profiled sheet metal from the edge or inside. The tool does not heat the material, makes turns at any angle, makes holes in hard-to-reach places, including complex shapes. No burrs form on the cuts, so there is no need for additional machining.

On the same principle as the cutters, operates a special attachment to the drill for cutting metal tiles (cricket). Only for private construction with flat or profiled materials. The electric drill scissor bit can cut a sheet vertically and horizontally. Makes round or shaped holes for the installation of ventilation systems, gutters and downspouts. The cut is very accurate, but it needs the right speed, otherwise the punch will bend the edges. An electric drill with a scissor head does not cause sparks, does not burn the polymer layer, works with steel, aluminum, copper.

The jigsaw cuts like a regular hacksaw, but with higher speed and precision. Use special interchangeable saw blades with a wave-shaped edge and fine teeth. They allow you to make a very smooth thin cut, without damaging the protective polymer coating on the surface of the roofing material. The jigsaw cuts not only straight but also curved lines. It is not possible to position the sheet on its side while working, because the profiled metal is not very thick and deforms easily.

  • ground and roof applications;
  • high speed;
  • easy to operate;
  • low cost of consumables (saws);
  • curved cuts can be made.

Screwdriver attachment

When choosing what to cut metal tiles, you can resort to the nozzle on the drill, which is an addition to the usual drill.

Work principle similar to electric scissors. the punch cuts a certain piece of material with every move of the tool.

You must be skilled with building tools to use the tool, otherwise you may have difficulty during cutting.

Hacksaw or electric jigsaw

The cheapest and most time-tested tool. a hand saw on metal. Does not require special skills and is available in almost every home. But at the same time, the saw can not perform shape cutting, for this you must resort to improved tools.

An electric jigsaw makes just as good of a move as a chopper, but it will take longer. The jigsaw with special attachments allows you to cut any profiled metal sheets.

It is interesting to know that the first mechanical metal scissors were designed for the installation of ventilation ducts and systems. Over time, the tool has improved dramatically and is now used for roofing work.
