Product Description

Product Description

Engineered for precision and durability, this industrial-grade diamond hole saw set features vacuum brazing technology that bonds 40/50 grit diamond particles to a high-strength steel core at 1150°C, achieving 3x longer lifespan than electroplated alternatives. The M14 hex shank ensures secure compatibility with all standard angle grinders (100-125mm discs), while laser-optimized cooling slots enable dry/wet drilling up to 8000 RPM. Perfect for creating clean holes in marble countertops, granite monuments, ceramic tiles, and glass panels without chipping.

FAQ

Q: Can it drill through 10mm thick tempered glass?
A: Yes, use water cooling and maintain 800-1200 RPM for best results.

Q: How to attach the vacuum base?
A: Press the base firmly on flat surfaces – the suction cup self-seals in 3 seconds.

Q: Is water cooling mandatory?
A: Required for glass and reinforced concrete; optional for tiles and marble.

Q: What's the diamond grit size?
A: 50/60 grit for fast cutting, 80/100 grit for smooth finishes.

Q: Compatible with hammer drills?
A: Only for rotary mode. Hammer function will damage the diamonds.
