Diamond Drill Bits Turbo Segments Granite Drilling

Diamond drill bits(sometimes called diamond hole saws) with turbo segments and steel pipe side diamond vacuum brazed for drilling stone ceramic concrete brick etc., common uses would be small projects such as drilling out sink holes for faucets.

Welding method: diamond segments silver welded or laser welded.

Dry or wet use(water coolant is much better for drilling performance and working life).

Suitable for stand drilling machines or electrical hand-held drillers or CNC machines.

Long steel pipe is available, pipe side without diamond is also available.
