Q1: What materials is this grinding wheel designed for?
A: Specifically engineered for grinding and polishing granite, marble, concrete, and glass surfaces. The plastic back design reduces heat buildup and minimizes material damage.

Q2: Why choose a plastic-back grinding wheel over metal-back?
A: Benefits include:

Heat dissipation: Prevents overheating on delicate materials like glass.

Lightweight: Reduces tool fatigue during prolonged use.

Vibration reduction: Provides smoother operation on uneven surfaces.

Q3: Can it be used for wet grinding?
A: Yes, it supports both wet and dry grinding. Wet mode is recommended for glass/polished stone to avoid cracks.

Q4: What tools are compatible with this wheel?
A: Fits standard angle grinders (4-5 inch) with a 5/8"-11 or M14 spindle thread. Check your tool’s RPM matches the wheel’s rating (typically 8,000-12,000 RPM).

Q5: How to prolong the wheel’s lifespan?

Avoid excessive pressure; let the wheel’s abrasives do the work.

Clean residue after wet grinding to prevent clogging.

Store horizontally in a dry place.
