Dremel SpeedClic Cutting Wheel Diamond

This diamond cutting wheel is designed for cutting very hard materials such as marble, concrete, brick, and ceramic floor tiles up to 1/2 inch thick.

Yes, this Dremel SpeedClic Diamond Cutting Wheel specifically requires the Dremel SC402 EZ Lock Mandrel for proper attachment and use.

The cutting wheel has a diameter of 38mm (1.5 inches) and a thickness of 3.2mm (0.125 inches).

The breathing holes help to reduce heat buildup during cutting, which extends the life of the disc and also minimizes debris, leading to a cleaner workspace and better visibility.

While diamond is very hard, this specific wheel is optimized for abrasive mineral-based materials like stone and tile, not typically for metals. For metal cutting, Dremel offers other specialized cutting wheels.

The Dremel EZ Lock system allows for quick changes: PULL back the spring-loaded sleeve on the SC402 mandrel, TWIST the old wheel off and the new wheel on, then RELEASE the sleeve to lock it in place.

Ensure you are using the correct tool speed for the material. Too slow a speed can cause glazing. Also, apply light, consistent pressure; don't force the cut. If glazed, try cutting a softer abrasive material briefly to 'dress' the diamond surface.

Reduce cutting pressure and allow the tool to do the work. Ensure adequate ventilation in your workspace. The disc's breathing holes help, but continuous heavy cutting can still generate heat. Take short breaks during prolonged cuts.

Ensure the Dremel SC402 EZ Lock Mandrel is correctly tightened in the tool's collet. When attaching the wheel, make sure the spring-loaded sleeve is fully pulled back, the wheel is twisted securely into place, and the sleeve is fully released and locked.

Verify that you are using the disc exclusively for hard, abrasive materials as intended. Using it on inappropriate materials or applying excessive force can shorten its lifespan. Always operate at recommended speeds for the material.
