Hi all! If your grinder cutting disc breaks, you shouldn’t throw it away right away. I'll show you how you can make a cutting attachment for a drill or screwdriver out of it. With which you can easily cut plastic or thin metal. For example, it is necessary to cut off a PVC pipe or saw off a bolt straight. In general, this is a necessary thing and will quickly come in handy on the farm.
Making a cutting attachment from a disk
We remove the fragments of the disk from the grinder, after first removing the plug of the power tool from the socket.
Then, you need to find a small circle as a template. I'll break off the disk ring. You can also use the clamping ring of an angle grinder for these purposes.
We apply it to the solid part of the broken disk and outline it with a marker.
Using ordinary scissors, cut a circle from the fragment along the contour of the ring.
You can also cut with metal scissors. Tsisk bsk for metal, it is not so thick and can be cut quite well by hand.
As a result, you should end up with a small circle.
We will use a regular nail as a drill. We cut off the cap with pliers.
We insert it into the drill and clamp it into the chuck.
Drill a hole exactly in the center of the workpiece.
In the end, this is what happened.
Take a long screw that fits the diameter of the hole. We put on the washer, put on the discs, another washer and tighten it all with a nut.
The useful cutting attachment is ready.
It can be used in conjunction with a screwdriver or drill. It cuts perfectly.
If you cut plastic, then the nozzle will not suffer from drift, but with metal the working life is short, due to the low speed of these tools.
This thing can be used to cut off a PCB board, which is perfect for radio amateurs.
In general, don’t throw away broken grinder wheels and reuse them! Good luck to all!
