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.
