Professional diamond coating technology – the diamond drill bits for ceramics feature industrial-grade diamond particles bonded to a high-strength metal matrix, providing unbeatable durability for bevelling and drilling through porcelain, granite, marble and glass. The 50 mm and 38 mm countersink bit set can handle everything from delicate tile edges to rugged countertop modifications.
Dual-Size Versatility Kit: This comprehensive chamfer tool kit includes 50 mm and 38 mm M10-threaded diamond drill bits, as well as a connecting rod. It offers the perfect size for any project. The bullnose router bit design creates smooth 45° bevels on tile edges, and the tapered profile allows precise enlargement of holes in stone sinks or backsplashes.
Cooling wax innovation: unlike standard tile cutter tool bits, which require water cooling, our chamfer bit contains integrated cooling wax that reduces friction during dry operation. This innovative technology prevents overheating when grinding ceramic floors or polishing stainless steel sink cut-outs.
Universal M10 compatibility: designed for 100 mm angle grinders and electric drills, these accessories can be installed instantly via the M10 thread (adapter included). The vibration-resistant connection ensures stable performance when edge-profiling shower tiles or creating drainage holes in granite countertops.
Professional results guaranteed – this diamond set has a lifespan five times longer than carbide bits. The aggressive diamond grit maintains sharpness through hundreds of linear feet, and the ergonomic design reduces operator fatigue during prolonged use.
