Diamond hole saws, glass hole saw drill bit with central pilot tip for glass, ceramic tiles, 18mm

Suitable for working with stone, tiles, ceramics, glass, granite, etc. The pilot bit in the center allows for precise hole cutting. Long service life: 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 simplifies 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 greater than approximately 1/2 inch. Product Description: 1. Smooth, precise finish to reduce cutting resistance and drilling pressure, increasing sharpness and water lubrication efficiency. 2. Produces clean, accurate holes in minutes with little to no chipping. The pilot bit in the center allows for precise hole cutting. 3. White zinc plating on the bits maximizes tool life with high corrosion resistance. Excellent for drilling glass or ceramic and significantly extends drill bit life. 4. Diamond drill bits and the clearance hole facilitate the entry of cooling water and the evacuation of chips and other drilling particles. Makes the drilling process easier. 5. Suitable for processing stone, tile, ceramic, glass, granite, etc. Works best with a power drill (not included). Specifications: Material: Diamond, Carbon Steel Features: with Center Pilot Bit Finish: White Zinc Plating Package: 1 piece x Diamond Drill Bit Usage Note: 1. Always use lubrication (water) when operating drill bits. 2. Low drilling pressure and increased use of water lubrication will prolong the life of the drill bit. 3. Do not use on concrete or for depths beyond approximately 1/2 inch. LRFR is committed to providing every customer with the highest quality of customer service.
