Instructions
1. The Rapid Z-CUT™ is designed for clockwise rotation, looking down on the 5/8-11 threaded hole,
and should not be used on a grinder or tool with the opposite rotation.
2. The Rapid Z-CUT™ mounts to a male 5/8-11 thread. Prior to use, ensure it is mounted tightly.
3. The Rapid Z-CUT™ is designed for wet use only. Use either center water feed or a sufficient
external water spray. Ensure enough water is used to avoid creating dust.

4. As the blades wear they will create an “apple core” shape. For maximum blade life the blades
should be rearranged often. Relocate the largest blades (normally the outer blades) to a
location where they will get more wear (normally toward the center of the stack). This can be
accomplished as follows (see Figure 1 & 2):
a. Clamp the Rapid Z-CUT™ upside down in a vise.
b. Using a 5/16 Allen wrench or hex wrench remove the socket head cap screw,
washer and cap from the arbor.
c. Remove the blades and rearrange as required.
d. Make sure that a grooved blade spacer is reinstalled between each blade. The
spacers may stick to the blades but can be pried off easily.
e. Be sure to maintain the correct blade rotation direction. Repeatedly reversing the
blade rotation will result in premature blade wear.
f. Reinstall the cap, washer and socket head cap screw and tighten.
