100mm Diamond Turbo Cup Wheel for Granite
The 100mm Diamond Turbo Cup Wheel is a professional M14 thread cup wheel for grinding, shaping, and edge profiling of granite, marble, and natural stone. The aluminium base and swirl turbo segment design keep the wheel cool during extended use, protecting stone surfaces from heat stress. Ideal for tombstone fabricators, worktop installers, and monumental masons. Suitable for wet and dry use.
Product Details
A precision 100mm diamond turbo cup wheel for grinding, shaping, and surface preparation of granite, marble, and natural stone — designed for stone fabricators, monumental masons, and kitchen worktop installers.
The 100mm Diamond Turbo Cup Wheel is a lightweight, fast-cooling grinding disc built for detailed shaping, edge profiling, and surface preparation work on granite and natural stone. Fitted with an M14 thread for use on standard angle grinders, the aluminium base keeps the wheel cool during extended grinding sessions while the swirl turbo segment layout delivers consistent, controlled stock removal without overheating the stone surface.
This is the go-to tool for tombstone fabricators, kitchen worktop manufacturers, monument masons, and stone installers who need a reliable, controllable cup wheel for hand-grinding granite and marble.
What Is the 100mm Diamond Turbo Cup Wheel Used For on Granite?
This cup wheel is used in the early to mid stages of granite surface preparation and shaping — before resin bond polishing pads are applied for the final finish. Key applications include:
- Grinding and shaping granite slabs, tombstones, and memorial stones
- Profiling and bevelling granite worktop edges before polishing
- Removing saw marks and rough texture from freshly cut granite surfaces
- Smoothing uneven granite surfaces before progressing to finer polishing stages
- Shaping granite and marble on construction and fabrication sites
- Surface preparation on granite tombstones before lettering and inscription work
- Removing surface imperfections from marble and engineered stone
Product Features
- Swirl turbo segment design — the spiral segment layout increases airflow across the grinding face, reducing heat build-up that can crack or discolour granite during extended grinding
- Aluminium base construction — lightweight body reduces operator fatigue during detailed hand-grinding work, with high thermal conductivity that dissipates heat rapidly away from the stone surface
- 100mm compact diameter — ideal for detailed shaping work, tight corners, edge profiles, and smaller granite pieces where a larger cup wheel would be difficult to control
- M14 thread — fits standard M14 angle grinders widely used by stone fabricators and monumental masons across South Africa
- Wet and dry use — wet grinding with water cooling is recommended for granite to maximise tool life and protect the stone surface from heat stress

Where Does This Fit in the Granite Finishing Process?
The Diamond Turbo Cup Wheel is a metal bond grinding stage tool — it is used before resin bond polishing pads to remove saw marks, shape edges, and prepare the granite surface. A typical granite finishing sequence would be:
- Coarse grinding — Diamond Turbo Cup Wheel (this product) to remove saw marks and shape the surface
- Medium grinding — progressing through finer metal bond or resin bond pads
- Fine polishing — resin bond diamond polishing pads to achieve a smooth finish
- Final polish — buffing compound or crystallisation for a high-gloss mirror finish

Frequently Asked Questions
Should I use this cup wheel wet or dry on granite? Wet use with water cooling is strongly recommended when grinding granite. Water keeps the stone surface cool, prevents heat stress cracking, extends the life of the diamond segments, and reduces dust. Dry use is possible for short bursts but not recommended for extended granite grinding sessions.
What grit stage is this cup wheel? This turbo cup wheel is a metal bond coarse grinding tool, used in the first stage of granite surface preparation to remove saw marks and shape the surface. It is not a polishing tool — once the surface is smooth and even, progress to resin bond diamond polishing pads for the finishing stages.
Can this be used on marble and engineered stone? Yes. The 100mm Diamond Turbo Cup Wheel is suitable for marble, engineered stone, limestone, and other natural stone materials in addition to granite.
Is this suitable for tombstone and memorial stone work? Yes. This cup wheel is widely used by monumental masons and tombstone fabricators for shaping granite memorial stones, smoothing surfaces before inscription, and profiling edges on tombstone bases and headstones.
