Cutting pipes at an angle: the advantages and disadvantages of different ways of doing the work

Pipes are a common building material. They are used in the installation of various systems. In the process of installation there are situations when it is necessary to join pipes at an angle. The technology of production of such works is not standard, but you need to know about it.

In order to create a complex connection configuration, pipe cutting at an angle is required. We will tell you how such operations are performed and what methods of cutting exist.

Preparing to work with an angle grinder on metal

the angle grinder is a relatively dangerous power tool. It is possible to get injured from a flying disk or a tool that has fallen out of his hands. In both cases, the danger is associated with the high speed of rotation of the electric motor of the device.

To increase the efficiency of the angle grinder, to expand its functionality, in practice such additional devices are used:

Their use can improve the quality of cutting of metal workpieces, increase the accuracy of the process. Also the working conditions from the point of view of safety are improved, its productivity increases.

The use of additional appliances allows to use the tool as a machine, designed for various types of work.

To maximize the safety of the cutting process, work on metal angle grinder should be in compliance with a number of rules. They are conventionally divided into preparatory and basic (working) activities.

Before you start cutting, it is necessary to perform a number of manipulations.

  • Wear special working clothes and shoes (with anti-slip soles), gloves made of thick cloth or leather.
  • Prepare, based on the characteristics and type of metal to be sawn, a suitable disc, then install it with the marking to the top, secured with a nut.

If possible, the material to be sawed should be securely fixed in advance, for example, in a vise, to remove its possible accidental movement. Do not hold the workpiece in your hands or between your knees.

Disk selection

Diameter, thickness and type of discs are selected depending on the type of work planned. Diameters range from 125 mm (small) to 250 mm (large, the most common) and affect the size (thickness and depth) of the cut.

Metal cutting angle grinder assumes a cutting disc thickness of 1.0-1.2 mm (professionals reach 2.5 mm). Shaped cutting on thin metal implies the use of a disc with a small diameter or already used.

When cutting with discs of any diameter it is necessary to use a protective cover. cover. In essence, it is a shield required to catch small metal scraps that form during cutting.

Peculiarities of work with an angle grinder

Safety precautions when working on a drilling machine

Modern angle grinder allows you to replace the sandpaper when working on metal. To avoid problems, it is useful to remember a few guidelines when using the tool:

  • hold the angle grinder with both hands while working. In the case of a back-blow, a firm grip on the tool should minimize dislocation. Otherwise, the risk of injury increases.
  • Work on a level surface, and be sure to maintain your balance.
  • Place the power cord on the opposite side of the disc. The operating instructions of the angle grinder impose these requirements to avoid short circuits and machine shock.
  • Hold the tool firmly in your hands when you finish work, until the disc comes to a complete stop.
  • If the power is out, unplug the tool from the outlet. Otherwise, the angle grinder may start to operate without control by the operator.
  • The work process is accompanied by the heating of the disks. Do not touch the disc after turning off the tool until it has cooled.

Clamping of material

How to properly cut metal with an angle grinder. Practical tips and recommendations

If long pipes are resting on supports, you must cut their hanging edge. If you cut them in the middle, then due to its own weight the metal will bend and clamp the disk.

If you are not familiar with the angle grinder, you should learn how to cut on unnecessary parts before you begin.

Cutting wheel can only take radial forces. Attempting to change cutting plane with blade inside metal part will break it.

The blade heel (the near bottom part of the wheel) is more efficient at cutting metal.

In order for the angle grinder and discs to serve long, every 5-7 minutes of work you need to take a break for 20-30 minutes. This rule is especially important for low-powered grinders that are afraid of overheating.

To increase the life of discs, especially expensive ones, and to cool the metal, the place of the cut should be watered. Two persons should preferably perform the work.

Aluminum is a very ductile metal. When cutting very thick workpieces, kerosene must be dripped into the seam, and fire safety rules must be observed.

For moldings, tin plate sawing, shaped carving, you should use exhausted discs. “splinters”, so do not immediately throw them away.

It is correct to cut the angle not in one step, but separately both shelves.

If long enough pipes, angles, fittings lie on supports, it is correct to cut the hanging edge. If you cut between the supports, the part will bend because of its own weight and will jam the blade.

Parts of large thicknesses should only be cut in a straight line. If you must cut a shaped piece, first make straight cuts, then remove the remaining unwanted parts.

Do not apply pressure to the angle grinder. This will cause the disc to jam or break and overheat the angle grinder. If the cutting process is slow, you should replace the blade.

The resulting cut should not be processed by the side of the disk. That’s why you use a different type of disc.

The melted particles of metal and abrasive, get on plastic products, glasses and car headlights, stick to them, and then it is almost impossible to remove them. So you have to remove or protect them before you start working.

Getting the right cut

Before you start cutting, you need to understand which side is better to do it from. If you have access from all sides, that’s very good, and the chance of making a mistake is reduced. Always take into account the direction of rotation of the disc. So, when sparks fly away from you, never make a “fork” when cutting a channel or metal profile. In the photo it is shown visually what I mean. You can’t cut with an angle grinder like that! When starting to cut metal the angle grinder should be positioned so that the cutting part is slightly elevated. Hold the angle grinder should be confident, but when you start cutting metal, you should not put pressure on the product. Try to hold the device straight. That way you not only get a straight cut, but also reduce the chance of clamping the disc. 80mm. f/7. 1/100s. ISO2000. June 30, 2021 )” The most important thing is to consider the basics of physics. The item to be cut should move to the side, not clamp the blade. It is best to create such conditions that it is in the weight. To do this, put something under the product. Example in photo. 6mm. f/2.8. 1/10s. ISO200. Aug 04, 2011 )”

Suitable for all types of wood. However, they will be limited to that material only, which is not really rational. It is better to buy discs for cutting wood that can cut both wood and metal. This is especially useful if you have to cut nails pounded into wood.

What disk to cut metal with an angle grinder

It is equally important to buy discs for the angle grinder on metal, suitable characteristics. When selecting, take into account the diameter and thickness of the products. these parameters determine the maximum depth of cut.

Very thin cutting discs (1-1,2 mm) are suitable for metal work. They allow you to make smooth cuts without much effort. For shaped treatment of thin rolled steel use a wheel for an angle grinder on metal of the smallest diameter.

Next, when selecting a device for the angle grinder to cut sheet metal, guided by the material you want to process. For cast iron, steel, aluminum and brass need different discs. You can read the information on the label for your specific application.

  • For stainless steel. Unlike other consumables, discs designed for stainless steel do not damage the protective film on the metal, which protects the material from corrosion.

  • For thin sections and pipes. Cut sheet metal with an angle grinder using discs with the appropriate diameter. Profile sheets and sheet metal. use products with small teeth. Angles and reinforcing bars. with discs of bigger thickness.
  • Roughing. Use for deburring and cleaning of weld seams. Thickness of discs is 5-10 mm. Processing is carried out with a tilt of the machine at an angle of 30-40 degrees to the surface.

Polymer pipes for plumbing

For plumbing, sewer and heating, there are several types of polymer pipes on the plumbing market:

  • Polyvinyl chloride pipes, known as PVC.
  • Metal plastic flexible pipes with reinforcement.
  • Cross-linked polyethylene pipes for plumbing and heating.
  • Polypropylene pipes with and without reinforcement.

PVC pipes. how to cut them

Polyvinyl chloride pipes, known as PVC can range in diameter from 50 to 400 mm, they are mainly used for sewage and ventilation. Polyvinylchloride pipes are low pressure materials, but also have a fairly rigid wall. For smaller diameters, a metal saw is usually used as a cutting tool (max diameter 200 mm). Universal cutter in this case, you can call an angle grinder with a cutting disc for metal (as an exception, you can use a disc for concrete with pobedite segments or diamond coating). If you need to cut a pipe larger than Ø 200 mm, but there is no possibility to connect to ≈220 V, then again it is done with a hacksaw, cutting the workpiece in a circle.

In order for the cut end in relation to the pipe to have 90°, the cutting trimmer line is outlined with a marker. this helps to adhere to the right angle and not go sideways. The cut, as a rule, turns out torn. melted pieces of plastic shavings will stick out in different directions and will not allow you to insert the pipe into the socket through the seal ring or rubber reduction. Therefore the cut should be deburred with a knife, and sometimes it is even necessary to make an external chamfer. this is relevant in cases where fittings and pipes from different manufacturers.

In the video, the process of cutting with an angle grinder:

I hope the preview was helpful. The pipe I’m cutting here is large in diameter and it took me only three minutes to cut it, of course the time required to cut a pipe with a diameter of 15 to 25 millimeters will be much less. When working with an angle grinder always wear glasses. a prerequisite for the safety of your health. So, dear friends, feel free to apply it in your work and may you always be successful.

The article before this line was originally written, and it is dedicated to help the santas with experience, as explained in the description to the video. And what I saw after ten months of posting it on YouTube:. 66 likes and 95 dislikes. Lots of negative Комментарии и мнения владельцев. Sad though, that’s not what I was going for. One viewer, named Vladimir Temlyak, wrote: “bullshit shows just to make money. I wonder what my income is here? The last commenter, under the nickname Jumatatatu ta, threw a couple of links to photos of crippled people. And then I realized that many of the “praising” my video viewers. are simple everyday people, in addition to frightened by the widespread scare stories on the Internet. The next line is for them:

That’s for these guys and was filmed a video, I wanted them to get acquainted with the disk thickness of 1.2 mm.

But I was already hurt by these dislikes, and therefore decided to study that on this issue is online. What was my amazement when I read the sites located in the top search engines: a lot of articles written about angle grinder copywriters. Who is it? Let me explain, a copywriter is a person who makes a living writing articles, that is, he is given a set of keywords (in our case. angle grinder, cutting disc, an accident), they say that the article should contain at least 2-3 thousand characters (a sign. a letter, symbol, space, etc.) and it should consist of two or three thousand words).п.) and he slaps an article. Might as well tomorrow he writes about ladybug, and the day after tomorrow about spaceships, and another day about the usefulness of the mix “Turboslim. I explained it clearly?

What can a reporter write in a news bulletin, for example?? Of course some stunning scoop, oh how they love the phrase: “blood was poured into two flights of stairs in the entrance and the like Never, no one in the news will tell that a Moldovan, or there Uzbek, or Russian, put on the angle grinder a circle of the wrong diameter A HEAVEN!

No, don’t think, I didn’t mean to “beg” the seriousness of working with this tool, but it is only a tool. a hand tool. Let me remind you again: a million people use it every day, and five hundred thousand of them operate it without the hood.
