A very useful drill or screwdriver head made from a used grinder disc. With the help of such a device, it is possible to cut metal or process its surface. This cutting tool can be very useful for those who do not have a grinder (angle grinder) or are not able to use it in hard-to-reach places.
What do you need?
- The remainder of the disc grinder.
- One washer the size of the inner diameter of the hole in the disc of the grinder.
- Two washers in diameter exceeding the inner diameter of the hole in the disc of the grinder.
Cutting nozzle manufacture
Unscrew the disk. As you can see, it should not be completely finished. If you don’t have a grinder, ask your neighbor or the nearest workshop, they will throw out such discs anyway.
We put a large washer on the bolt. It does not have to be rectangular. Since finding large diameter washers is problematic, I made from what was at hand. The outer diameter of the washer should be larger than the hole for mounting the disk.
Then we put a disk on a bolt. To make it stand strictly in the center, install a washer with a diameter approximately equal to the diameter of the mounting hole of the disk.
We put on all this a big washer, the same as in the beginning.
We tighten everything well with a nut.
As a result, we got such a very useful nozzle for a drill or screwdriver.
Clamp the bolt in the chamber of the drill.
And sawing metal. For example, a steel pipe.
It cuts perfectly. There are absolutely no sparks, as when working with angle grinders, since the speed of the drill is very low compared to the grinder.
Of course, in no case should you neglect the safety precautions when working - at least safety glasses must be on you. Due to the low revolutions, the cutting tool did not become less dangerous, and all protection requirements must be observed.
Using this nozzle, you can clean the surface of the metal from paint or rust, cut the pipe in a hard-to-reach place, and much more. Useful thing, do it yourself - you will not regret it.
