Application Instructions

Securely mount the 4.5″ blade onto the angle grinder, ensuring the max RPM of the tool does not exceed 13,500 RPM.
Always wear ANSI-approved safety goggles, hearing protection, and a dust mask/respirator.
Clamp the workpiece firmly to prevent movement.
Start the cut at the edge of the material.
For deep cuts, utilize multiple shallow passes rather than a single deep pass.
Use water (wet cutting) whenever possible to maximize blade life and reduce dust.

Pro Tips

Periodically “dress” a dull blade by cutting a few passes through an abrasive material like an old cinder block to refresh the exposed diamonds.
When dry cutting, allow the blade to cool by idling it out of the cut every 30-60 seconds.
Maintain a steady feed rate; do not force the blade, as this can cause premature diamond loss.
Ensure the grinder flange nuts are tightened securely to prevent slippage.
Check the blade for cracks or damage before every use.
