Special Teeth Diamond Cup Wheel

EXTRACUT T-Segment Diamond Cup Wheel is designed for efficient surface grinding and material removal on concrete, stone, masonry, and similar hard materials. Featuring premium sintered metal-bond diamond segments with a unique T-shaped segment profile, this cup wheel delivers excellent stock removal, superior heat dissipation, and extended service life when mounted on standard angle grinders.

Key Features

• T-Shaped Segment Design — The distinctive T-profile segments significantly increase the exposed surface area to air compared with conventional flat or turbo segments. This enhanced airflow dramatically improves heat dissipation during dry grinding, reducing segment glazing, thermal stress, and workpiece damage.
• Sintered Metal-Bond 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 service life than electroplated alternatives.
• Ventilated Steel Body — Precision-drilled cooling holes work in tandem with the T-segment profile to maximize debris evacuation and thermal management during both dry and wet grinding operations.
• 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 full 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), stone and masonry grinding (granite, marble, terrazzo edge chamfering and rough shaping), aggressive material removal on building and renovation sites, and flooring substrate prep prior to tiling or epoxy application.
