Diamond Grinding Wheel – Vacuum Brazing Diamond Bullnose Router Bit

Johnson Tools Vacuum Brazed Diamond Hand Profiler Router Bit 1-1/4 Inch Full Bullnose Coarse Profiler Wheel with 5/8-11 Thread for Granite Marble Concrete Countertop Edge Profiling

Achieve professional-grade edge profiles on natural and engineered stone slabs with our Premium Vacuum Brazed Diamond Hand Profiler Router Bit. Specially engineered for stone fabricators, contractors, and DIY experts, this full bullnose profile wheel delivers exceptionally fast, precise, and smooth coarse shaping on countertop edges.

Utilizing state-of-the-art Vacuum Brazing Technology, industrial-grade diamond particles are permanently bonded to the steel core. This advanced process prevents diamond loss under heavy friction, allowing the wheel to cut faster and last significantly longer than traditional electroplated profiling bits. The coarse diamond grit ensures rapid material removal without cracking or chipping fragile stone surfaces.

Equipped with a standard 5/8″-11 female thread, this hand profiler seamlessly attaches to variable-speed angle grinders or wet polishers. With a recommended operating speed of 3,500 to 4,500 RPM, it operates smoothly in both wet and dry applications, giving you maximum flexibility on job sites.
