Challenge Paper Drill Sharpener with 3-Flute Reamer

Instructions

1) Carefully place a hollow drill bit in the holder section of the sharpener.

2) Make sure the reamer set screw is tightened, so that it doesn't spin during sharpening.

3) Insert the holder section back into the sharpener end, being careful not to bump the drill bit into the sharpening reamer to avoid chipping.

4) Rotate clockwise while maintaining even pressure on the drill bit and sharpening reamer.

5) Turn by hand until the drill bit is sharpened, usually just a few turns.

6) Remove the drill bit from the holder section by bumping the base of the drill bit on a flat surface to pop it out.

7) Return the drill bit to service. If the drill bit remains too dull, repeat the above steps.
