Round hole in metal with angle grinder
You can try to cut a round hole with an angle grinder. How to cut a circle with an angle grinder part 1 how to cut a smooth hole in metal with an angle grinder.
Short numerous cuts are made around the perimeter of the entire outlined contour until they merge into a single contour.
In this case, the hole is a polygon with a large number of sides and the more there are, the more the polygon will look like a circle. It should be noted that this option is chosen only in the case of thin metal. a maximum of three millimeters.
The finished hole definitely needs additional processing, which allows it to get a more correct shape. If the hole is large, it can be machined with an angle grinder with a thick disc. To do this, place a circle inside hole and at the same time make sure that it is in the same plane with the metal sheet. How to cut a circle with an angle grinder By turning on the angle grinder, you can grind the contour.
How to properly cut drywall
There are some helpful tips to make your job easier:
- Drywall is a flexible material. In order not to break it during work, you need to put the sheet on a stable flat surface.
- When cutting a large sheet, it should be done gradually.
- The workplace should be free of moisture, otherwise the material will get wet and become unusable.
- Which side to cut the drywall from is not so important. However, it is best to cut on the surface that will attach it to the wall.
- When cutting a profile, don’t worry about jagged edges. They will subsequently be covered with a drywall sheet.
- When working with the material, it should be understood that it can crumble strongly and create dust. Be sure to protect your eyes and respiratory system.
Edge processing
When the drywall is cut, the edges should be leveled slightly so that they do not have
The final stage of material preparation includes its fascination. To do this, you need to cut off a few millimeters of gypsum from each edge (about two-thirds of the sheet thickness). The chamfer is removed with a plane or knife at an angle of approximately 45 degrees.
After installing drywall, all gaps between the material canvases must be putty. When the seams are dry, you can start painting the surface or pasting it with wallpaper.
Angle Grinder Application
an angle grinder is used when working with metal of small thickness. You can form a round hole with this tool by following these step-by-step tips:
- Before cutting a circle in metal with an angle grinder, markings are made so that its contours are clearly visible.
- Along the entire length of the outlined drawing, short segments are cut by the disc of an angle grinder, which will eventually connect.
- The shape will look more like a polyhedron than a circle. Therefore, after the end of cutting, the product is processed and cleaned until the edges are sufficiently even and smooth. An angle grinder can also be used for processing. If the circle has a wide diameter, you can grind the contours with a large disc.
When processing the cut out wheel with an angle grinder, you should be careful that the disc is inside the hole and, at the same time, is located in the same plane with the worksheet.
Wooden parts
In order for outdoor furniture to serve for a long time, you first need to pay attention to the condition of its prefabricated elements. It is better not to use old cracked boards and beams with holes left from nails. There should be no traces of mold or damaged areas on the surface.
The durability of the bench depends on the type of wood. Oak will last much longer than pine or birch.
Blanks may vary in quality. For example, according to GOST, lining is divided into four classes. The evaluation criterion is the uniformity and strength of the structure, as well as decorative qualities.
New products must be processed before use. Better to start by drying them. Even a flawless array contains excess moisture. It is removed to protect the tree from temperature and humidity deformations. When wet and dry, the fibers change their shape. In addition, frozen water expands and destroys them from the inside.
Drying is carried out in the open air or indoors. Do not turn on the radiator at full power. otherwise moisture will be removed unevenly, which will lead to irreversible deformations. Products are stacked in piles, making a layer between each tier for normal air circulation, and kept for several days.
Before you make a bench with a back with your own hands, the workpieces must be protected from the effects of the external environment. The dried material is impregnated with antiseptics. There are ready-made solutions that do not need to be diluted on your own.
They are non-toxic and non-corrosive to metal fasteners when in contact with the array. Use sodium fluoride solution, oil antiseptics. Technical oils have high performance, but when they evaporate, they emit substances that are harmful to health.
After impregnation, the surface is covered with plastic wrap so that the mixture completely penetrates into the structure, and then dried.
For legs and supports that are in contact with the ground, use special means, for example, NEOMID 430 Eco. They are highly resistant and do not wash out in a humid environment. Racks after such processing can be dug into the ground without fear for their condition.
After the antiseptic dries, the parts are varnished. Linseed oil is used as a primer. Semi-natural formulations are well suited for this. Modified drying oils with additives have improved properties. They improve adhesion to the topcoat and provide a solid base for application. The coating dries within 24 hours, after which you can start painting and varnishing.
It is better to use oil and polyurethane compounds. Polyurethane is characterized by increased resistance to external influences. They protect well from moisture and scratches, do not darken over time. The product is applied in two stages using a brush or spray bottle. The first layer is dried and sanded with fine sandpaper, then the second is laid.
When creating a wooden bench with a back with your own hands, unusual materials are often used: logs, stumps, thick branches and even interior items. In order for them to last as long as possible, they must be processed, like simple workpieces.
Fasteners are nails and screws. Nails hold in the array worse. They have to be constantly knocked out. To connect the heavy parts, they are placed on anchors. All metal fasteners must be galvanized, otherwise traces of corrosion will become noticeable in the first year.
How i cut perfect circle without any guide using my angle grinder
Professional carpenters grind the parts, creating grooves and protrusions on their sides that match in size. For reliable fixation, wood glue is used. Traditional methods are equally reliable, but there are other options. An unusual way is to use a rope. It stretches over time. Knots and windings will have to be updated frequently.
The husband took an iron barrel, an angle grinder, and white paint. Now the neighbors are jealous of our street fountain
I love the sound of running water. It soothes and relaxes the nerves. And since we had free space near the kitchen window, we decided to turn one of the empty barrels into a fountain. My husband did a great job. Now we have become very comfortable in the yard!
Metal marking
The outline of the hole to be cut should be drawn on the metal. Cutting a round hole in metal isn’t as difficult as drilling a hole in glass, but it’s more troublesome. The marking is carried out using a marker, a ruler, not a marking compass. For a hole consisting of straight lines, the marking is carried out using a ruler, not a marker. Use a compass to mark the round hole. To make the oil more visible, it is pointed with a marker.

How to cut a straight hole in metal with an angle grinder. How to cut a circle from metal in 2018 how to cut. My method is suitable for metals 1-5 mm approximately, more.
Metal has different thicknesses and not every one of them can be taken by any device. So with a device with a capacity of no more than one hundred and fifty amperes, it will be possible to cut metal with a thickness of no more than four millimeters.
Cutting speed in this way is highly dependent on the thickness of the electrode. The fastest way to work is thin electrodes, but they have their drawback. rapid combustion, leading to frequent replacement of the electrode. During the replacement of the electrode, the metal has time to cool down and has to be heated first.

Gas cutter application
A circle in metal of medium thickness can be cut with a gas cutter. The work takes place in several stages:
- The outline of the circle is outlined.
- The tool burner ignites.
- Burning torch adjustable.
- Carefully and slowly the torch is carried out according to the drawn drawing.
Using this method, you can cut a hole in the metal, which has a width of about four or five millimeters.

How to cut a hole in metal at home
In metal, you can cut any holes for sure thanks to such modern cutting methods as plasma non-laser cutting of metal.

How to saw with a jigsaw correctly
The tool allows you to cut almost any material, namely metal, wood, plastic, ceramics, and even stone. The cutting blade is capable of plunge cuts, straight cuts, curved cuts, as well as cutting circles. In the article we will analyze how to saw with a jigsaw correctly, to ensure that the cut matches the given markings.
How to cut perfect circles with an angle grinder
The jigsaw can have a normal and pendulum motion. In normal travel, the blade moves vertically, cutting through the material on its way up. The tool, which has a pendulum stroke, additionally, when moving up, feeds the blade forward. This achieves a higher working speed, and also reduces blade wear due to the deflection of the saw in the opposite direction when moving down. A reasonable question arises about how to saw with a jigsaw with a pendulum motion? The work is carried out in the same way, but it is taken into account that with the maximum deviation of the saw, it is best to cut soft wood and plastic. When cutting chipboard, fibreboard, soft metal, thick wood, it is necessary to reduce the range of motion of the blade. This mode is not recommended for use at all when working with steel sheets.
To cut a round hole, you need to drill an initial hole in the workpiece, into which the file is then inserted. After that, a cut is made at the mark. If a rectangular or square hole is to be cut, then the cutting is done in a straight line of the mowing line to each of the edges, after which the blade is retracted slightly and follows the curve of the mowing line to the next side. This will cut all four sides. After removing the cut area, the remaining triangular parts are cut out.
If it is not possible to make an initial hole in the workpiece, plunge sawing can be used. To do this, the working jigsaw is tilted forward until the file reaches the workpiece. Gradually, the file will make a through hole in the workpiece. The plunging point of the saw should be located in the cut-off part of the workpiece.
The jigsaw is able to cut bevels, as a result of which the edge of the resulting product will have an even cut in one direction. For such a cut, it is necessary to change the installation angle of the jigsaw ski, and then cut.
Cutting a circle in thick metal
In order to outline the exact contours of the figure that will be cut out of metal, you should use a ruler, a marking compass and a marker.
First, using a ruler, the required width of the compass connector is set so that it corresponds to the required circle diameter.
Then the center point of the circle is determined on the metal plane.
From it, with the help of a compass, contours are outlined.
To make them clearly visible during robots, they should be drawn with a marker.
