Diamond hole saw for marble, ceramic, tile, concrete, glass, 30 mm

The drill bits' cutting edges feature a cross-section design to reduce cutting resistance and facilitate chip removal.

First, position the drill at a 45-degree angle, then drill the hole vertically (note the low operating speed of approximately 800-1000 RPM).

Suitable for drilling stone, ceramic, glazed tile, glass, etc. You must continuously add water for cooling during drilling.

Suitable for bench drills, electric drills, and machine tools with a drilling function, but not for impact drills (the impact function cannot be used for drilling).

The universal triangular drill bit shank effectively prevents slippage during drilling and can withstand higher torque.
