Why did I buy this particular model of angle grinder or grinder

Angle grinders (grinders) began to appear in large quantities in everyday life 20 years ago. For someone else, but for me - angle grinder was an excellent alternative to a manual hacksaw for metal and a welding machine in cutting mode.

LBM selection criteria

Before buying a grinder, I had a little experience with a similar power tool. Once I took an angle grinder with a power of about 2.5 kW from a relative. On the basis of "communication" with this angle grinder, I understood what did not suit me. It was very powerful. When I pressed the start button, the grinder tried to jump out of my hands. And when the cutting wheel went a little obliquely, then miserable fragments remained from it. I knew that there was a less powerful similar tool, as I saw up close the work of various models, both small and large.

Therefore, in the market, I set the following conditions to the seller:

1. Power - no more than 1.5 kW.

2. The maximum diameter of the cutting disc is no more than 200 mm.

3. Smooth start!!!

4. Two handles.

5. Metal gear housing.

It turned out that fulfilling my requirements was not so difficult.

What i bought

I purchased an angle grinder "Proton MSHU-180/1300" with the following technical characteristics:

1. Power - 1300 W.

2. The maximum diameter of the cutting wheel is 180 mm.

3. The number of revolutions at idle speed - 8000 in 1 minute.

And, of course, the duralumin crankcase and soft start.

Included with this angle grinder were:

1. Protective cover.

2. Additional handle.

3. Wrench for fastening circles.

4. Key for attaching the protective cover.

5. Spare graphite brushes.

I was also pleased: the simplicity of changing the brushes and the presence of rubber plugs in the holes in the body for the additional handle.

My impressions

I'm happy with my choice. For 10 years of operation, graphite brushes have not even been half-erased. He cut not only steel, but also home concrete (paths and blind area). I bought various attachments: conical metal brushes, a diamond wheel for tiles, a sector disc for grinding.

I noticed the following features:

1. When cutting cast iron (cylinder liner) there is not enough machine power. I had to loosen up the pressure.

2. When cutting factory concrete (posts, cast fences), ordinary circles are not suitable, they are erased almost to no avail. Only diamond should be used.

3. Cutting tiles is not good. The line will never be straight. The disc breaks out small pieces of glaze, regardless of the direction of rotation relative to the tile surface.

4. When using a massive metal brush, a “frenzied” vibration occurs, which causes severe pain in the hands. You have to either press the start button or release it so that the angle grinder does not gain high speed.

I am a fierce opponent of using angle grinders when cutting wood. This is very dangerous, especially when using toothed steel wheels (for circulars). Better to sweat with a hacksaw than run away from a grinder that has escaped from your hands. Several acquaintances of mine have already suffered from such amateur performances.
