This drill sharpener comes with a full set of instructions to ensure even a novice can sharpen drill bits and get good results every time.
Sharpening is controlled by means of a moving carriage which slides left to right, and also rotates the drill bit on its axis, which yields the correct relief angle. The sliding carriage has a feed screw for fine control, and a dressing stone is fitted to ensure a sharp cutting surface.
The ABS housing includes fixing holes so it can be permanently mounted to a workbench. Also available: adapters for sharpening of small drill bits, spare grinding discs.
