The Precision Choice for Smooth Surface Prep
"When a project moves from heavy removal to surface finishing, the scratch pattern becomes critical. At Supreme Diamond Tools, we engineered our Standard Turbo Series with an ultra-high segment density—up to 40 segments on our 7-inch wheel. This creates a more continuous contact surface, allowing you to achieve a smooth, swirl-free finish on granite and concrete that requires significantly less time for secondary polishing or coating application."
— The Supreme Diamond Engineering Team
The Supreme Professional Turbo Diamond Cup Wheel is specifically designed for contractors who prioritize a clean, refined finish alongside fast material removal. Unlike aggressive row-style wheels, the high-density turbo segment design minimizes deep gouging, making it the premier tool for stone restoration, floor leveling, and delicate masonry work.
| Diameter | Segment Count | Hub Thread / Arbor | Recommended Speed |
|---|---|---|---|
| 4" (100mm) | 26 Segments | 5/8"-11 or 7/8"-5/8" | 15,000 RPM Max |
| 4.5" (115mm) | 27 Segments | 5/8"-11 or 7/8"-5/8" | 13,300 RPM Max |
| 5" (125mm) | 28 Segments | 5/8"-11 or 7/8"-5/8" | 12,200 RPM Max |
| 7" (180mm) | 40 Segments | 5/8"-11 or 7/8"-5/8" | 8,500 RPM Max |
Managing Scratch Patterns: When transitioning from a coarse Double Row wheel to this Turbo wheel, use a cross-hatch grinding pattern (side-to-side, then up-and-down). This ensures that the high-density turbo segments effectively "erase" the deeper gouges left by the aggressive rowed segments, leaving the surface ready for higher-grit polishing pads with minimal effort.

Q: When should I use this Turbo wheel instead of a Double Row wheel?
A: Use the **Double Row** for heavy, bulk removal and leveling. Use this **Turbo Series** when you need a smooth, cleaner finish or when working on natural stones like marble and granite where chipping is a concern.
Q: Is this wheel safe for dry grinding?
A: Yes. It is fully optimized for dry use in masonry and stone. However, for the longest segment life and a dust-free workspace, wet grinding is highly recommended.
