Crowne Caviar 4.5" Ultra-Premium Grinder Blade — The Finest Cut in the Lineup

On high-end finish work, the visible edge is everything — and a blade that chips or chatters ruins expensive tile in a heartbeat. The Caviar sits at the very top of Crowne's grinder-blade lineup for exactly this work: a laser-cut, ultra-thin diamond edge that glides through porcelain, ceramic, and stone with surgical accuracy, leaving exceptionally smooth, virtually chip-free cuts.

The laser-cut ultra-thin rim reduces cutting resistance and chipping, a reinforced steel core cuts vibration and deflection for straighter, more controlled cuts, and the whole blade runs notably smooth and quiet. It's made for tight tolerances, detailed layouts, miters, and finish work on standard 4.5" angle grinders. For fast everyday straight cuts at a friendlier price, the best-selling Butter is the workhorse, and the Paragon sits between them as a premium straight-cut blade.

Why Tile Pros Choose It

  • Surgical accuracy: Laser-cut, ultra-thin diamond edge for minimal resistance
  • Virtually chip-free: Protects delicate porcelain and high-end finish edges
  • Smooth and quiet: A refined, low-noise cutting experience
  • Rock-steady: Reinforced steel core reduces vibration and deflection
  • Finish-grade control: Tight tolerances, detailed layouts, and miters
  • Top of the lineup: Crowne's ultra-premium blade for high-value materials
  • Yes, it comes in a tin: The fanciest thing in your tool bag, and it earns it

Pro tip: Pair it with water for the cleanest possible cuts — it cuts like a glass blade but faster, with barely any polishing after. Let the ultra-thin edge track on its own with a light touch; forcing a thin blade is what makes it flex.
