continuously on the same spot on the wheel will cause grooves to be worn into the
wheel. The wheel may crack or become damaged more easily, and grinding of other
objects will be difficult.

TWIST DRILL BITS
Drill bits are best sharpened on a
sharpening jig, available at most
hardware stores, but can be “dressed
up” on your grinder. Begin on one
side of the point at the existing angle,
then twist the bit while maintaining a
constant angle with grinding surface.
Sharpen only the tip. This technique
requires considerable practice, so
take your time and make a few “dry
runs” first with the grinder off. Be
sure to maintain the original cutting
edge angle as this is important to
the efficiency of your bits. One tool
rest has a V-groove that is correctly
angled for most drill bits.
COOLANT TRAY
When grinding, metal objects
become heated quickly. It is
important to keep moving the object
back and forth across the face of the
grinding wheel and to cool the object
frequently using the coolant tray.

NOTE:
Using a metal object, like a screwdriver,
is not recommended as it may damage the
grinding wheel.
