DSPIAE AT-TH 3.175mm Clamp Holding Handle

NOTE: Make sure to rotate the bit so it matches your grip on the triangular handle.

Simply put, it's an aluminium holding tool for chisels/scribing bits or other 3,175mm/1/8" bits, with a screw-clamp to tighten around the bit.

However, there is more to it:
1. It's triangular, it doesn't roll off of your table
2. It has magnetic caps, top and bottom
3. It's hollow, so if you push your bit too far in, you can push it through instead of trying to pull it out
4. You can use the cap's magnet to pick up small metal objects
