Diamond Drill Bit: Uniformly grained electrolytic diamond for superior wear resistance. The hole saw offers high precision, a smooth cut, and chip resistance, providing excellent robustness and durability.

Large Through Hole: Diamond hole saws with through holes facilitate the entry of cooling water and the removal of chips, making drilling easier. Cuts are smooth and flat, without scratches.

Clean and Smooth Cut: Diamond hole saws offer high precision, a smooth cut, and no damage to the edges. The drill bit is coated with white zinc, which effectively extends its lifespan and provides excellent corrosion resistance.
