Steel blade for miter saw

How to choose the right one?

In modern renovations, miter saw blades for aluminum, plastic and stone are most often required. These materials are actively used to create modern decor.

In order to choose a blade for soft metals and polymers, you need to know that there is a difference in sawing a hollow structure or a dense solid. The quality of the cut here mainly depends on the number of teeth. So, to obtain a result close to ideal, with hollow structures, it is better to use discs with a large number of teeth. Dense material is better sawn with a small-toothed nozzle.

An important criterion is the thickness of the disc and the material from which it is made. A solid carbide (high carbon) metal cutting tip is the best choice. It lasts longer and can be re-sharpened. The same cannot be said for welded teeth.

This quality is inherent mainly in European brands. The cost when choosing an expensive brand name pays off during operation.

Good quality can be noted in the brands Bosch, DeWALT, Makita, CMT. The same firms also produce construction tools, including miter saws.

If we talk about the angles of inclination, then for soft materials such as plastic, it should be negative. This gives the cleanest cut possible. The shape of the teeth is quite varied. The universal drive may be the best option. You can never go wrong with him.

A simple alloy of metals is not enough to perform a high-quality cut in stone. A harder material is needed here, in the role of which is diamond sputtering. In this case, the decisive factor in the selection is the grain size of the abrasive coating. The larger it is, the less beautiful and high-quality the end cut will be. Fine diamond plating is much more useful and clean. But to prevent engine overheating, it is better to choose not the smallest value.

It should be noted that the blades of such circles only vaguely resemble teeth. Their design is more like a periodically divided, monolithic cutting blade. The shape is explained by the fact that the sawing is carried out due to the friction of the abrasive against a hard stone.

Concept

A miter saw is a tool designed to make straight cuts at a given angle. The saw cut angle can be either 90 degrees or 45. Its main advantage is that it copes well with long details and unusual shapes of surfaces. A striking example of these is a plastic floor plinth.

But this tool has other features.

The miter saw can cut a large number of equal (given size) miter and straight slots. That is why it is a must in the set of craftsmen for the manufacture and assembly of furniture and doors.

The appearance of this unit resembles a conventional circular saw (circular) mounted on a movable arm. It allows the discs to descend not only vertically, but also at any angle of inclination. This tool can cut various materials:

  • wood;
  • metal (in particular aluminum);
  • plastic;
  • a rock.

As with any saw, the type and quality of the blade depends on the material chosen. For the most effective work, you need to choose the right component.

Features of the

Saw blades have a number of basic parameters that help differentiate them.

Namely:

  • outer diameter;
  • inner diameter;
  • number of teeth;
  • tilt of the teeth;
  • the shape of the teeth;
  • product thickness.

Outside diameter is generally not a significant indicator for cutting speed. He is responsible for the cutting depth. It can be determined by the inner diameter of the saw cover. A large circle (305-355 mm) is not placed on a product with a smaller casing diameter. (By the way, it is not recommended to remove the protection for safety.) Most often, products with an indicator from 130 to 250 mm are taken for such a saw.

The inner diameter must have the same value with the dimensions of the power shaft on which this product is fixed. If it is larger, then during the operation of the saw, the off-center disc creates large vibrations, which leads to severe wear of the bearings and the shaft itself, as well as breakage of the disc or its teeth. In addition, such a fastening is a gross violation of the work regulations, and is dangerous for humans.

The cutting speed depends on the number of teeth on the disc in direct proportion. In addition, a large number of them gives a smoother and more accurate cut. But there is also a significant drawback of this approach. it is the increased load on the sawing tool engine. There are disks:

  • with a large number of teeth (from 80 to 90 pcs.);
  • with an average number of them (from 40 to 80 pcs.);
  • small-toothed (up to 40 pcs.).

For high-quality sawing, the inclined angle of the teeth is also very important. It is fixed by the deviation of the cutting edge of the tooth from the radius of the saw blade. This parameter can be:

  • standard (the angle varies in the range of 5-15 degrees);
  • positive (tilt 15-20 degrees);
  • negative (0 to minus 5 degrees).

Finally, the configuration of the prong. Each shape is designed for a specific cut. Therefore, a tooth is distinguished here:

  • flat. cuts longitudinally at high speed;
  • trapezoidal flat (alternation of high in the form of a trapezoid and low flat teeth). cuts wood, plastic and soft types of metals (aluminum);
  • replaceable (the teeth have an alternate slope to the right and left). helps to cut wood, chipboard and composites cleanly both along and across;
  • combined (one flat cutter follows four replaceable ones). completely universal;
  • interchangeable with a larger sloping side. used for choppy types of material, as well as for clean cuts at right angles.

As for the thickness of the saw blade itself, the thickness of the cut depends on it. The standard is 3.2 mm. If the indicator is higher, then this will reduce the amount of material, and if much less, then this will lead to overloading of the equipment and possible deformation of the disk.

However, when working with each type of material, there are also peculiarities of saw accessories.

A tool such as a miter saw is not familiar to everyone. Despite the large number of materials that this tool can cut, its main purpose is specific. Therefore, such a saw is often used by professional finishers. At home, it does not become necessary so often. However, when you do not want to overpay for repairs, it makes sense to purchase all the necessary tools to make your work easier.

But in this case, you need not only to understand the principles of working with it, but also to understand the consumable parts of this tool. The main of these parts is the cutting disc.

Circle replacement

When performing repairs, even at home, the periodic change of materials also requires the replacement of the saw blade. It is not difficult to change it, but it is still worth knowing the correct sequence of actions for your own safety.

It is necessary to start by installing the protective plastic casing (if any) in the upper position. To do this, unscrew the side auxiliary bolt, raise the structure, and then fix it with the same bolt, just in a different position.

Next, take a hexagon, which unscrews the clamping bolt in the center. In this case, on the back of the saw, it is necessary to press the button of the shaft locking mechanism, which is a stopper. It prevents the shaft from moving. Therefore, while holding it, you can press out the central bolt using the hexagon. Then the bolt must be unscrewed (you can use your hands), remove the side stopper (looks like a wide washer) and then the disc.

Installation is carried out upside-down. The disc is put on the shaft, then a lock washer is placed, then the bolt is screwed in by hand until it stops. To clamp the nozzle, you must press the button, and, while holding it, tighten the central bolt to the limit using a hexagon.

Once the saw blade has been mounted, it can be checked for strength with a slight longitudinal movement. If there is no backlash, the installation is correct, and you can start cutting.

How to choose the right circular saw for metal

Chapter 1. Saws for metal. Introduction.

Metal saws are widely used in industry and everyday life. At the household level, a saw for metal. This is a hand saw with replaceable blades. We will see such a tool in the first lines of search results in any search engine.

The industry is characterized by more productive samples: the most important, at the moment, equipment from this category is a band saw for metal, although 20 years ago, the most common type of saw for metal in workshops was a mechanical hacksaw. Such machines still remain in some places and, even more surprising, they are even found on the market as new ones! A mechanical hacksaw is a morally outdated and noisy machine, as a rule, with a fixed vise. Replaceable tool for him. hacksaw blade. Wears out unevenly. more in the center, the edges remain intact, which means that economically this type of tool is less efficient than a disc or belt blade.

A more expensive, but also much more productive machine was and remains a circular saw for metal. Its obsolete version can be called a segment saw, otherwise called a Geller saw.

Now, on disk cutting machines with automatic or manual feed, they are used as blades made of high-speed steel. these blades have a comparatively higher number of teeth, and so do the blades with carbide teeth. HSS saw blades, not to be confused with saw blades for wood, are most often used for cutting galvanized steel air ducts. This is due to the large number of teeth and, therefore, a smaller distance between them, called the tooth pitch. This factor allows you to cut very thin steel without undermining.

For productive cutting of steel wheel or aluminum slabs, it is best to use an automatic circular cut-off machine. On such a machine, saw blades with carbide teeth are installed. The disc rotates at high speed and is cooled by oil mist. Well, if you need to cut a steel beam or pipe, then the number one is now in all industries. this is a band saw. Band saw machine. economical and quiet type of equipment for cutting workpieces, both thin and thick wall.

As for our promise to give advice on the selection of a circular saw for metal, the above types of tools are not entirely relevant to this topic. Our company specializes in relatively light and simple hand-fed saws and cut-off machines and a carbide-tipped saw blade that works without additional cooling. We just want to be objective and give as complete an understanding of the state of affairs in the field of saws for metal in the present and recent past as possible.

Chapter 2. Circular saws for dry cutting of metal. Appointment

Circular saws are a convenient and relatively inexpensive way to cut steel workpieces in workshops and on-site. Several companies in the world specialize in their production and the design of some models is very similar. Basically, it concerns hand-held circular saws and pendulum cut-off machines.

Circular saws for metal are designed for cutting steel sheets up to 12 mm thick, as well as profile sheets and sandwich panels up to 80-100 mm thick. As the name implies, circular saws of this type, while performing work, are held in the hands. Their design sometimes allows the disc to tilt at an angle of up to 45 degrees to the plane of the support platform, and this gives great versatility. You can even create a weld bevel in one move when cutting a sheet.

Unfortunately, the ease and speed at which circular saws cut thick steel when compared to a conventional angle grinder, for example, is offset by the relatively high cost of saw blades. However, the only alternative can be called sheet shears or laser cutting, which cannot be compared with hand saws, either in terms of price or mobility.

So, hand-held circular saws will allow you to cut efficiently and accurately:

  • low carbon or low alloy sheet steel up to 12 mm
  • lentil leaf
  • grating
  • profile sheet with a wave height up to 84 mm
  • metal roofing
  • sandwich panels.

Slightly less effective, but still possible to cut with these saws:

  • steel pipes and profiles. it is difficult to see where the cut will go, so if accuracy and repeatability are very important, it is better to use pendulum saws
  • scrap metal such as old wagons, car bodies or agricultural machinery. during cutting, displacement of structures and pinching of the disc is possible. This can lead to damage. In these situations, where accuracy is not important, use flame cutting. However, be aware of the explosion hazard.
  • stainless steel. this is due to the property of stainless steel to conduct heat poorly. Because of this, all excess heat rushes through the disc, which leads to its warping and deterioration. Better to use something liquid cooled.

Pendulum cut-off machines are very good for cutting long products such as pipes, profiles or circles. The name pendulum saws comes from the form of movement in an arc around the swing axis. These saws are more suitable for classification. small-sized or portable machine for cutting metal. The maximum diameter of a circular saw produced for this type of machine, at the time of this writing, was 400 mm. However, the most common so far can be called 355 mm or 14″ disk. Cutting machines with a disc of this diameter can cut workpieces with a cross section of up to 130 mm. In some cases, it is permissible to cut a rectangle measuring 95×180 mm.

What is the best way to charge a pendulum circular saw with a carbide blade:

  • pipes made of steel or cast iron
  • rolled steel, in particular corner, channel or I-beam
  • cable tray with wall thickness from 1.5 mm and more
  • shaped pipes or a closed profile of a more complex cross-section

Slightly less effective, but it is still possible to saw with such machines:

  • open thin-walled profile with a wall thickness of less than 1 mm. large vibration, you need to use tabs to prevent crumpling in a vice. Helps, but performance drops
  • cable without armor and steel core. in general, an aluminum cable will cut without problems, and any steel element in the cable is deliberately hardened or made of spring steel. no trouble. Therefore, we advise you to cut the cable with care.
  • steel circle. the saw blade will quickly fail in any metal with a thickness of more than 6 mm, but we have experience in cutting a circle with a cross section of 50 mm or more. Rage multipurpose discs are not suitable for this purpose.
  • stainless steel. pipes made of AISI 302, 303 or 304 steel can be cut, but only if there is sufficient time for the disc to cool between cuts. Thus, cutting becomes unproductive or wasteful.
  • carbon steel. discs do not do well with carbon steel. Mark 30 and above requires caution and deliberation. The disk resource will also decrease.

Well, at the end of the review, we cannot ignore the Evolution Rage multipurpose miter saws. Many people are interested in the ability to cut steel profiles, pipes and other workpieces with such saws. Based on our experience, we can say that there is such an opportunity. But not more. And here’s the thing.

Sliding miter saws can cut fairly wide workpieces. They are very well suited for precise sawing of boards at different angles. The workpiece is clamped at a certain distance from the cutting line of the cut, so as not to block the turntable. In this case, the clamp is a light clamp. This is all right for cutting wood planks and even aluminum planks used in the production of car trailers, but does not match the stresses when cutting steel profiles. Vibration generated in the long pull arm is detrimental to carbide teeth. Another factor. it was only in 2020 that the blades mounted on miter saws began to match the saw rotation speed, before that the blade speed was too high. Therefore, it was not necessary to talk about long-term cutting of steel profiles or pipes with a miter saw. If you need to cut steel from time to time, then this equipment is quite suitable. If the task is to constantly work with rolled steel. our recommendation is cutting machines or hand-held circular saws for metal.

Is it possible to cut metal with a miter saw?

This is what our guests sometimes ask. For our regular customers, this issue has already been resolved.

Most likely you are already aware of the ability of circular saws to cut metal, especially if you are already familiar with EVOLUTION products. over, industrial circular saws for metal are specifically designed to cut steel or non-ferrous metals regularly. And stainless steel. periodically. But this limitation is due to the capabilities of the discs and the features of dry cutting of chromium-nickel steels.

RAGE professional hand-held circular saws and cut-off machines also successfully cut steel when the sheet thickness does not exceed 6 mm, and the profile wall. 3 mm. However, by using a steel cut-off wheel used in the EVO 180 saw or S355CPS cut-off machine, these limits can be surpassed without damaging the machine.

Serial cutting of steel profiles or pipes with EVOLUTION miter saws used to be ineffective. We have already covered this topic in previous articles. And nevertheless, with infrequent work with rolled steel, miter saws of this brand show themselves much better than other brands, on which they have put a disc for metal. The main advantages of EVOLUTION miter saws over competitive models:

  • a robust gearbox originally designed for cutting steel
  • reduced rpm, optimized for steel discs
  • more than 20 years of experience of the company in the development, production and sale of circular saws for metal

This is without touching the carbide wheel itself on steel. Just a lot of people ask the question “Will I be able to cut steel with a miter saw for wood if I put a blade on it for metal?

What has changed in over 10 years of EVOLUTION RAGE metal miter saws production?

In 2020, the company introduced a new generation of special cutting discs. Now, the steel discs with a diameter of 185 mm are designed for speeds up to 5800 rpm. A special professional disc R185TCT-20MS is offered for the R185SMS miter saw, and for saws with a 255 mm disc. matching cutting disc for steel.

So in the question “is it possible to cut steel with a miter saw” there have been significant advances.

Follow these guidelines when working with steel workpieces on miter saws:

  • securely attach the workpiece to the base, if the standard clamp is not enough, use additional devices
  • fold the saw advance to the forward position and secure with the set screw. reduce the number of places where vibration is possible
  • do not apply significant force to the saw, let the blade cut at the expense of speed, not pressure

Types of saw blades for metal

For the most part, metalworking equipment is divided into several factors. The main one, perhaps, is the direction of using disks:

  • for soft types of steel. hardened steel discs with a straight tooth shape and sharpening at a certain angle are used;
  • for hard steels. use hardened or carbide steel discs with brazed teeth. The shape of the tooth and sharpening can be very different. straight, angular or trapezoidal. The combination of tooth shape and sharpening is also encouraged, which increases the quality of the cut;
  • for aluminum and copper. discs with a trapezoidal tooth shape and a large number of teeth, up to 100 pieces. This ensures the required cut quality and does not damage soft metals.

According to the material of manufacture, saw blades are divided into two types:

  • monolithic discs. in which all parts are made of the same metal, without soldering. The price for such discs is quite low. The teeth of these discs can be re-sharpened. This naturally affects the quality of the cuts and the durability of the blade itself. Basically, such discs are used for circular saws and rough cuts;
  • carbide discs. made of durable metal with tungsten or cobalt soldering. The special shape of the tooth and the sharpening allows for precise and clean cuts. Such discs are more expensive, but they also last much longer. For a miter saw, this is the best tooling choice.

What equipment are the presented saw blades suitable for??

Due to the thickness of the disc, the outer and bore diameters, the number and size of teeth, as well as their inclination, scoring saw blades are most often used for cutting when working with such equipment:

hand-held circular saw;

panel saw (horizontal and vertical)

This equipment is used for finishing cuts of panels, so it is designed for ripping or cross cutting. But since the height of the teeth of the discs presented is 8 mm, and the number of teeth exceeds 64 pieces, it is best to use such circles for a cross cut.

Cross-cutting with such a blade will facilitate the processing of wood, and you will receive a quality product at the end. Saw blades for cutting wood with a large number of teeth make it smooth, they do not split the material and retain its original structure.

In the construction industry, craftsmen often use a miter saw, which is designed to cut wood and thin metal and plastic materials. Miter saws can work both at right angles and at an arbitrary angle. Therefore, there are two types of discs that are used in the trimming process: dusty and scoring.

The presented saw blades for trimming are used for processing the following materials:

If specialists use the necessary circular discs for trimming, then the cutting of panel materials can be done without a movable unit. Discs for such a cut are reliable, fit snugly to the machine or to the saw. Qualitatively and with a small amount of waste, they process the material.

Long-lasting cutting and trimming discs for laminated panels

Saw blades for cutting plywood are made of durable material. stainless steel. It is also called chromium alloy. This material has many advantages:

Thanks to the use of this material, saw blades have a long service life. more than 50 years. The disc does not lend itself to corrosive influences: it does not rust, does not crack. The surface of the disc is carefully sanded, so it does not leave fingerprints on it, and it also does not lend itself to mechanical stress.

The saw blade for cutting plywood made of stainless steel is very durable, the quality of its work does not depend on the weight of the materials. Such a disc has heat-resistant properties, so it will not melt the material with which it is working. Since stainless steel does not crack, the saw blades stay clean. No dirt or harmful bacteria can enter the cracks. Scoring saw blades for cutting made of chromium alloy can serve with respect for more than half a century.

Application area

A saw or cutting disc for metal can be used in various fields of construction. Also, this tool is often used in the repair process for the purpose of dismantling structures. When buying a saw blade, it is worth remembering that there is no universal model that is ideal for all types of work. Therefore, if you are planning several activities at once that use cutting and saw blades, then it makes sense to buy a set of different models. Cutting disc for metal is suitable for longitudinal and cross cuts of metal structures, and for aluminum. for working with soft metals.

Discs for processing and cutting metal

When carrying out construction and installation work, as well as dismantling metal structures, sawing solid sheets of iron and for other purposes, a saw blade for metal is used. This type of hand tool can be used in hand saws, end saws and other types of saws. It is easy to use, but when working with saw blades, you must carefully follow safety precautions, since it is this tool that is a frequent cause of accidents. When choosing a saw blade, first of all, you should focus on the type of work for which it will be used.

Market situation

Many world-famous companies are engaged in the manufacture of saw and cut-off wheels. So, in 1998, the Fangda company appeared on the market, which specializes in the manufacture of high-quality tools for processing metals, wood and other materials. The company’s products are widely known in many countries of the world and are distinguished by reliability, durability and a large selection.

Sigma is another well-known manufacturer of discs for metal working. Its products are the European level of quality, durability and affordable prices.

Among other companies, the Dewalt company can be distinguished. Disks from this company are slightly more expensive than from other companies, but this is compensated by their high quality.

The emergence of the instrument

The first cutting discs for working with metal appeared relatively recently. Their emergence was caused by the need to work with sheet metal, as well as the intensification of the use of metal structures in construction and repair. The advent of saw blades for hand-held and construction milling cutters greatly facilitated human labor and increased work efficiency many times over. Modern cutting discs differ little from their ancestors in terms of design, but when creating them, special alloys are used that ensure high strength and durability. Otherwise, such disks do not change.

The future of saw blades

Some tools don’t change over time. This also applies to saw blades for metal. Their design is so simple and at the same time reliable that it does not require any significant modifications.

In the near future, new materials may appear that will make such discs even stronger and more durable. Also, already now, tooth coatings are actively used, which reduce friction, thus increasing the wear resistance of the tool.
