Roloc Flexible Diamond Discs – Quick-Change Sanding for Stone & Glass
Roloc-style flexible diamond discs for fast, tool-free disc changes on angle grinders and die grinders. The twist-lock Roloc backing system eliminates wrench changes between grits — ideal for production lapidary work, stone fabrication, and glass grinding where rapid grit progression is essential. Flexible diamond coating conforms to curved and contoured surfaces for consistent, even abrasion.

Frequently Asked Questions
-
Q: What is a Roloc disc and how does the quick-change system work?
A: Roloc is a twist-lock disc system where the disc attaches to a compatible mandrel with a simple push-and-twist motion — no wrenches or tools required. To remove, twist in the opposite direction. This allows rapid grit changes during production work without stopping to change tools. -
Q: What grinder is compatible with Roloc diamond discs?
A: Roloc discs require a compatible Roloc mandrel (sold separately) that fits standard angle grinders and die grinders with a 1/4" shank. Verify your grinder accepts a Roloc mandrel before ordering. -
Q: Should Roloc diamond discs be used wet or dry?
A: Wet use is strongly recommended for stone and glass. Water cools the workpiece, flushes swarf, and extends disc life significantly. For dry use on certain applications, reduce speed and pressure to prevent overheating. -
Q: What grit sequence should I use for stone surface grinding with Roloc discs?
A: Start with 60 or 120 grit for initial shaping, then progress through 220, 400, 600, 1,200, and 3,000 grit. Follow with a cerium oxide pad or polishing compound for a final mirror finish. -
Q: Can Roloc flexible diamond discs be used on curved surfaces?
A: Yes — the flexible backing allows the disc to conform to moderately curved and contoured surfaces, making them suitable for curved stone edges, bowl interiors, and irregular lapidary shapes.
