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.
