tip. Carbide tips ultimately become dull, and using
large, oversized carbide tips will induce extreme impact
energies into the machine's structure.
• Debris Retention: Rayco's cutting tool patterns are
designed to minimize the retention of debris in between
the cutting tools. This debris can cause imbalance. This

debris can also become a dangerous projectile. Non-

(Use the 1/2" hex key provided with the machine.)
2. Clean all dirt from the cutting wheel (1) and teeth (2).
3. Check the cutting wheel for cracks. Replace the wheel
if it is cracked.

Sharpening Teeth
DO NOT allow any tooth to wear too much before sharpening.
Discard any tooth that has lost more than 1/8" of original bite.
Remove the tooth from the cutting wheel to be sharpened.
Tooth Sharpening Guidelines:
1. Obtain an unused tooth for comparison.
NOTICE
DO NOT hammer the tip of a tooth. Due to the
super hardness of the tooth, it is brittle and may
chip from such treatment.
NOTICE
Sharpening cemented carbide cutting teeth requires
a special process. Have your teeth sharpened only
by a qualified machinist for obtaining a proper edge
and to avoid injury.
2. Discard any tooth that has lost more than 1/8" of original
bite, whether lost through usage or grinding.
3. Grind off a minimal amount from the end, just enough
to restore the original taper and radius on the end. The
end of the cemented carbide tip and the end of the steel
shank should be flush after grinding.
