8. The drill bit should exactly touch
the grinding wheel and will be
held at the correct angle.
9. Turn the unit on and start
sharpening.
• Exert a slight downward
pressure onto the bit and pivot.
• The bit should be constantly
moved during sharpening by
swinging the bit holder back
and forth as indicated by the arrows.
• Examine bit according to the sharpening hints below.
10. Turn the clamp over and sharpen
the other edge in the same way.
11. Try to ensure that both sides of the
drill bit are sharpened, using the
same amount of time and
pressure.
• Check that both sides are the
same shape and that the tip is
exactly in the centre of the drill.
• Check that the trailing edge of
each cutting surface is lower than the leading edge.
• Check that both sides are equal.
12. Repeat the above steps as necessary.
13. Switch the power unit off and ensure the grinding wheel has stopped
before removing the sharpener attachment from the power unit.
SHARPENING HINTS
• If the tip of the bit starts to turn blue, it is overheating. Reduce the
amount of pressure and sharpening time. Allow the bit to cool
between sharpening cycles.
• If one edge is longer than the other, sharpen the short edge of the
drill bit 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.
