Hydro Handle HH14BIT 1/4 Inch Vacuum brazed Bit 8 mm Shank

The Hydro Handle HH14BIT 1/4" Vacuum Brazed Diamond Bit is designed for drilling small, precise holes in tile, quartz, granite, marble and other hard materials. Its vacuum brazed diamond coating provides a thick and exposed diamond layer that cuts aggressively while protecting brittle surfaces from cracks and chip-out. Engineered side holes improve cooling and clear slurry away from the cutting edge, while the lathed one-piece steel body resists stress and vibration under high RPM use. The drill bit achieves maximum speed and life in water-feed setups while also providing dependable results in dry drilling when required. Built with an 8 mm round shank, it fits universally in 3/8" and 1/2" drills for direct compatibility on the jobsite.
