Make of high quality tungsten steel, can be used to work with iron, steel, carbon steel and other metals and non-metals such as marble and jade. Up to HRA85 can be processed.
When you use this set of rotary burrs with a rotary tool, the processing speed is ten times faster than when you use a manual file tool. Rotating burr set can be used instead of the small wheel with the handle to make less dust.
There are a lot of industries where tungsten steel grinding heads can be used. They can be used for things like engraving and beveling. They can also be used for things like hollowing and reaming.
Durable: This grinding head is safe and easy to use. These tools are made of high-speed steel, but they are ten times as durable as small grinding wheels.
It’s easy to use.

No bits were in the box I got. You can see right away that this clear case is empty. I thought it was supposed to have 10 tungsten carbide bits in it, but I only got a clear case that you can see is empty. Nobody knows how someone could put it in an envelope and not notice that it was empty. Sorry I have to get another thing and then go out of my way to drop this off at a place that participates. Send me the pieces without a case this time and call it even.
