A diamond grinding cup wheel for heavy-duty stone and concrete work, engineered for fast material removal and durable performance. Builders and renovators gain confidence when tackling rough slabs and high points, finishing jobs more quickly and with fewer passes. Is the SHDIATOOL Diamond Grinding Cup Wheel the right choice for site work and slab preparation given its coarse grit and rugged build?
⚡ At a Glance
- • Grinding Performance: Aggressive removal thanks to turbo segments and 40/50 grit for quick stock removal
- • Best for: Builders, stonemasons and renovators preparing slabs and removing high points
- • Not ideal for: Fine finishing, polishing tasks or delicate stone work requiring a smooth surface
115mm sintered turbo-row cup wheel with a 22.23mm bore and 4.5mm workable thickness. Multi-air holes and heat-treated steel combine with high-concentration diamonds for fast, durable grinding.
Fast, aggressive material removal, with turbo segment configuration
Turbo segments increase exposed diamond cutting edges and provide a larger contact area, while a sintered bond holds coarse 40/50 grit diamonds for heavy stock removal. Large segment geometry speeds cutting on hard surfaces.
Quickly levels concrete high points and cuts through granite or marble for efficient slab preparation and shaping.
Improved cooling under load, with multi-air holes
Multiple air holes channel airflow across the grinding surface to reduce friction and dissipate heat, limiting thermal stress on segments. Lower operating temperature reduces risk of premature glazing or bond failure.
Maintains cutting performance during longer runs, reducing downtime for cooling and extending usable life.
Long-lasting durability, with heat-treated steel and high-concentration diamonds
Heat-treated steel resists deformation under pressure while a higher diamond concentration improves cutting efficiency and wear resistance. The sintered construction bonds diamonds securely for sustained abrasion performance.
Offers consistent removal rates over many jobs, cutting the need for frequent blade changes on site.
