Flexible Diamond Flap Wheels – Contour Grinding for Stone & Glass
Flexible diamond flap wheels for grinding, smoothing, and finishing curved, contoured, and irregular surfaces on stone, glass, and ceramic. The overlapping flap construction conforms naturally to complex profiles — delivering consistent abrasion on surfaces that flat discs and belts cannot reach. Ideal for lapidary carving, stone sculpture, glass edge work, and detailed finishing on angle grinders and die grinders.

Frequently Asked Questions
-
Q: What makes a flap wheel better than a flat disc for contour work?
A: The overlapping flap construction allows the wheel to flex and conform to curved, concave, and irregular surfaces that flat discs cannot follow. This delivers consistent abrasion on complex profiles without gouging or flat spots. -
Q: What tools are diamond flap wheels compatible with?
A: Small shank sizes (1/4") fit die grinders, rotary tools, and angle grinders with a collet adapter. Larger sizes with 5/8"-11 arbor fit standard angle grinders directly. Always verify the shank or arbor size matches your tool before ordering. -
Q: Should diamond flap wheels be used wet or dry?
A: Wet use is recommended for stone and glass to cool the workpiece, flush swarf, and extend wheel life. For dry use on certain applications, reduce speed and work in short passes to prevent overheating. -
Q: What RPM should I use with diamond flap wheels?
A: Use the lowest effective speed for your material — typically 3,000–6,000 RPM for stone and glass. Higher speeds increase heat and wear. Never exceed the maximum RPM rating printed on the wheel. -
Q: Can diamond flap wheels be used for lapidary carving?
A: Yes — diamond flap wheels are excellent for lapidary stone carving, sculpture surface finishing, and detail work on irregular gemstone shapes where drum machines and flat pads cannot reach.
