Segmented Diamond Cup Wheel

EXTRACUT Segmented Diamond Cup Wheel is engineered for aggressive surface grinding and material removal on concrete, stone, masonry, and similar hard materials. Featuring premium sintered metal-bond diamond segments arranged in a symmetrical segmented pattern, this cup wheel delivers fast stock removal, stable grinding performance, and extended service life when mounted on standard angle grinders.

Key Features

• Sintered Segmented Diamond Construction — Industrial-grade diamond particles embedded throughout the metal bond matrix via high-temperature sintering. Fresh diamond is continuously exposed as the wheel wears, ensuring consistent cutting performance and significantly longer life than electroplated alternatives.
• Ventilated Steel Body — Precision-drilled cooling holes improve heat dissipation and debris evacuation during dry or wet grinding, reducing segment glazing and thermal damage to the workpiece.
• Metal Bond Durability — Formulated with iron, copper, and tungsten carbide powders for balanced wear resistance. The controlled wear rate maintains optimal diamond exposure across the tool's lifespan.
• Dual Grinding Mode — Suitable for both dry grinding (on-site convenience) and wet grinding (dust suppression, extended segment life).

Applications

Ideal for concrete surface preparation (leveling, coating/laitance removal), masonry grinding (brick, block face smoothing), stone fabrication (granite/marble edge chamfering, rough shaping), and flooring substrate prep prior to tiling or epoxy application.
