Description
The go-to contour blade for granite vanity bowl cutouts. The Weha 5" Matrix Diamond Turbo Contour Blade is engineered specifically for vanity bowl cut-outs in granite, marble, engineered stone, and quartz. Its side diamonds extend a full 1-3/8" down the blade — ensuring complete side cutting through 3cm stone without a second pass. Ultra-grade diamonds, strong core steel, and a no-vibration design make this one of the most reliable contour blades available for this application.

Why the Side Diamond Depth Matters
Standard contour blades cut on the rim only — leaving the sides of the cutout rough and requiring additional grinding. The Matrix Turbo Contour Blade's side diamonds extend 1-3/8" down the full blade face, cutting cleanly through the entire thickness of 3cm granite or stone in a single pass. No secondary side grinding required.
