SHARPENING PROCEDURE 1. Connet the drill to the drill bit

sharpener and clamp the drill into a vice to hold the sharpener upright.

2. Connect the drill to the mains supply.

3. Put a single drill bit (HSS only) into the appropriate hole.

Please note that this drill bit sharpener is not suitable for sharpening masonry bits

4. Pull the trigger on your drill.

Exert a slight downward pressure onto the bit and rotate the bit back and forth about 20 degrees while sharpening.

The bit must be kept in motion whilst in the drill bit sharpener.

5. Remove the drill bit after approximatley 5-10 seconds of sharpening.

SHARPENING HINTS

If the tip of bit starts to turn blue, it is overheating. Reduce the amount of pressure and sharpening time. Cool the bit in water between sharpening cycles.

If one edge is longer than the other, sharpen the shorter side a little more.

If you are sharpening a broken (rather than blunt) bit and the time required to restore the shape is too long, rough the bit into shape first using a bench grinder.

Ensure both sides of the drill bit are sharpened using the same amount of time and pressure.

6. Repeat the above steps as necessary.
