Diamond Hole Saws Glass Hole Saw Drill Bit with Central Pilot Bit for Glass, Ceramic Tiles 28mm

Suitable for processing stone, tile, ceramic, glass, granite, etc. The pilot bit in the center allows for precise hole cutting. Long life: Reduced drilling speeds, low drilling pressure, and increased use of water lubrication will extend the drill bit's lifespan. Clearance hole: Diamond drill bits and the clearance hole facilitate the entry of cooling water and the removal of drilling chips. Facilitates the drilling process. Sharp & Smooth cut: The diamond hole saw creates high-precision, smooth cuts without broken 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 beyond approximately 1/2 inch.

Product Description
