extreme edge of each tooth 1¼" away from edge of
pocket.
• When using Rayco SUPERTEETH®, because of one
piece construction, no pre-setting of the tooth is required.
• Make sure teeth are placed in coordinance with wheel
rotation.
• After setting each tooth pair, tighten the socket head
bolts to 135 to 145 foot-pounds.
There are four types of Superteeth, as shown in the diagram

Sharpening of 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.
The teeth must be removed from the cutting wheel for proper
sharpening.

Tooth Sharpening Guidelines

NOTICE
Do not hammer the tip of a tooth. Due to the super
hardness fo the tooth, it is brittle and may chip.
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.
1. Obtain an unused tooth for comparison.
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.
