 If the point is not in the centre (one
side is sharp, the other is not), re-
grind the shorter side. This fault is
avoided by uniform pressure on the
drill bit during grinding on both sides
as well as identical grinding times.
 Particularly for drill bits with large diameters and major
wear, grinding with the drill bit sharpener may not lead
to a satisfactory result. Note that the device is mainly
intended for periodical re-sharpening but not for the
complete re-working of much worn thick drill bits.
