Diablo Diamond Rim Cup Wheel for Masonry
Diablo's diamond cup wheel grinds concrete and masonry. L-shaped diamond segments leave a clean, smooth finish and avoid gouging and swirl marks, and extra-wide slots pull dust out of the cut. Diablo says it removes material up to 3X faster than standard diamond cup wheels.
Two sizes for angle grinders, 4-1/2 in. and 7 in. Diablo lists the wheel for concrete, stone, natural stone, granite, mortar, brick and block.
Dry grinding, 5/8 in.-11 thread. The wheel threads straight onto the grinder spindle, so check your spindle thread before you order.

Frequently Asked Questions
Can I grind wet?
No. Diablo lists this cup wheel for dry grinding.
What thread does it need?
A 5/8 in.-11 thread. There is no bushing, so a grinder with a different spindle thread will not take it.
Cup wheel or cut-off disc?
A cup wheel grinds a surface. To cut through concrete, brick or block, use a segmented blade.
Which size do I need?
Match the grinder. The 4-1/2 in. wheel is rated to 13,280 RPM and the 7 in. wheel to 8,450 RPM, so check the grinder's no-load speed against the rating.
