Achieving a perfect bullnose or beveled edge on a granite countertop requires the right foundational tools. Our Diamond Cup Grinding Wheels are engineered specifically to curve and refine the raw edges of stone, removing saw marks and irregularities to prepare the surface for polishing pads.
The set includes two high-performance designs:
-
The Spiral Segment Wheel (right) is your primary tool for heavy shaping and aggressive stock removal, allowing you to quickly knock down sharp corners and create the initial curve of the profile.
-
The Turbo Segment Wheel (left) provides a more controlled, refined grind that smooths out the shape and prepares the stone for the lower-grit polishing stages.
Both wheels utilize a premium industrial diamond matrix that stays sharp even when working with the densest granites, ensuring a consistent profile along the entire length of your workpiece.
Key Features
-
Edge Shaping Precision: Specifically designed to curve and contour stone edges without the bouncing or skipping common in standard discs.
-
Industrial Diamond Concentration: High-grade diamonds provide the aggressive cutting power needed to reshape granite and engineered stone.
-
Dual-Action Design: Features a Spiral rim for rapid shaping and a Turbo rim for smoothing the profile.
-
Heat-Dispensing Vents: Integrated cooling holes prevent the stone from overheating, which can lead to micro-cracking during the shaping process.
-
Balanced Steel Core: Each wheel is precision-balanced to reduce vibration, protecting the stone edge from chipping while protecting the user’s hands from fatigue.
Benefits
-
Flawless Profiling: Create professional-grade curves, from simple chamfers to complex bullnose edges, with total control.
-
Pre-Polishing Excellence: Dramatically reduces the time spent in the polishing stage by creating a smooth, uniform surface first.
-
Enhanced Tool Life: The robust diamond bonding outlasts dozens of traditional abrasive stones, making it a cost-effective choice for busy workshops.
-
Clean, Chip-Free Results: The specialized segment geometry ensures a clean grind that doesn’t blow out the delicate underside of the granite slab.
