Tungsten Carbide Chamfering Drill Bit 1/4" to 3/4" Uniburr, Bolt Thread Repair Tool for Removing Burr, Quick Release Hex Shank Deburring Tool for Metal, Rod, Tube, Screw, Dowel, Sheet,Pipe

Sometimes you have to cut off a screw. Getting a nut on the end afterward can be a challenge. This tool makes it easy. It works perfectly with both my drill and my hammer drill. It's super sharp, so it takes almost no time. you also don't have to be perfectly aligned - it's pretty forgiving.

Works ok. Not so great on steel, but should be good on softer metals and other materials. Worth having, if you work with metal, and you get both sizes. The countersink bit is good quality, plus you get a 1/4" hex extension.

Wish I had this years ago. Saves me from having to rebuy a lot of hardware

works as it should

Should have bought a long time ago!

Thought they was for steel but no just wood

Works great to remove burs off cut bolts and rods.

Works as it should seems pretty well made
