Diamond Glass Hole Saw Drill Bit with Center Pilot Bit for Glass, Ceramic Tile 20mm

• Suitable for processing stone, tiles, ceramics, glass and granite, etc. The pilot bit in the center helps cut precise holes
• Long Life: Reduced drilling speeds, low drilling pressure, and increased use of water lubrication will extend the life of the drill bit
• Clearance Hole: Diamond drill bits along with the clearance hole facilitate the entry of cooling water and the evacuation of chips from the drill bit. Facilitates the drilling process
• Sharp & Smooth Cutting: The diamond hole saw creates high-precision smooth cuts without broken edges. White zinc plating on the bits maximizes tool life with high corrosion resistance
• Please note: Water is required for lubrication and cooling when drilling. Do not use on concrete or for depths beyond approximately 1/2 inch.
