65mm Diamond Drill Bit Glass Hole Saw Core Drill Bit with Central Pilot Bit for Porcelain and Glass-Ceramic Tiles

Specifications: Size: 65 mm / 2.56". Suitable for processing stone, tiles, ceramics, glass, granite, etc. The pilot bit in the center allows for precise hole cutting.

Long Lifespan: Reduced drilling speeds, low drilling pressure, and increased use of water lubrication will extend the drill bit's lifespan.

Clearance Hole: The diamond drill bits and the clearance hole facilitate the entry of cooling water and the removal of drilling chips. This makes the drilling process easier.

Clean, Smooth Cut: The diamond hole saw creates smooth, high-precision cuts without chipped edges. The white zinc plating on the tips maximizes tool life with high corrosion resistance.

Please note: Water is required for lubrication and cooling during drilling.

Do not use on concrete or for depths greater than approximately 1/2 inch.
