Review on 🔧 Wokesi 10Pcs 1/4" Solid Tungsten Carbide File Cutter Taper Points Burrs Grinding Head Set - Fits Rotary Tools (6mm Shank Diameter), Endmills, Bits for Enhanced Cutting Performance by David Forleo

When changing the steering wheel on a motorcycle, I had to remove the old lock cylinder from the steering column. To do this, drill 2 x 6 mm bolts. The first is easy, the second not so much. I had to grind the rest of this stud and couldn't go back and forth with the drills. I ordered this set and hoped it would work. They did. And fast too. Bolts removed in minutes. Just be aware that the effect of using these bits is quite powerful. I don't know why or what got them hooked, but it was pretty scary when they got hooked. Gloves and goggles, and don't be afraid to get anything you're working on dirty.
