OPERATION AND

MAINTENANCE OF THE

The GRS Diamond
Power Hone is designed for a
long, useful service life. The spindle is driven
by a smooth belt system at 240 RPM. The
diamond wheel supplied with your hone provides
true diamond performance. This means carbides,
hard metals, ceramics, and other exotic
materials are all within the capability of your
Power Hone. Replacement diamond wheels are
available from GRS Tools in several grits for a
wide range of applications.

TOOL SHARPENING

When using the Power Hone, hold the
tool relatively stationary while the rotary
motion of the wheel sharpens the tool.
Sweep the tool slowly across the working
surface of the wheel. This extends wheel
life by using the entire cutting face and
prevents grooving. The Power Hone is
designed mainly for fine tool sharpening
and finishing. Use a bench grinder to rough
shape tool points, then give them a fine
finish on the Power Hone. This will save
time and extend diamond wheel life.

Engraving & Jewelry Tools

The Power Hone was originally
designed to sharpen engraving and jewelry
tools. Sharpening fixtures to hold the
gravers to the precision angles required
for fine engraving tools are available
from GRS Tools. See the “accessories”
section or the GRS Tools catalog for the
sharpening fixtures that are available.

NOTE:

For very delicate work such as heeling
small gravers, try using the diamond wheel
with the machine turned off. This will
prevent removing too much material.

Household & Shop Items

The Power Hone is useful around the

house and shop to sharpen items like;

scissors, knives, craft tools, hobby

tools, chisels, wood and metal lathe

tools, etc. With the ceramic lap wheel

you can even put an edge on a

razor blade.

POWER HONE
MAINTENANCE

The GRS Power Hone
is virtually maintenance
free. For normal service,
yearly lubrication is
required. For extremely
heavy service, the motor
should be oiled every 6
months with several drops
of SAE 20 non-detergent
oil. Oil holes for the two
motor bearings are
accessible by removing
the front switch plate. Turn
machine upside down and
remove four screws: two
holding the front rubber
feet and the two between
them (See ILL A).
