Diamond drill bit Hole saw compatible with glass, center guide, compatible with glass ceramic tiles 25mm

Suitable compatible with processing stone, tile, ceramic, glass, granite and more. Center pilot bit helps cut precise holes Long life: slower drill speed, lower WOB and increased use of water lubrication will extend bit life Clearance hole: The diamond drill bit is combined with clearance hole, conducive to cooling water inlet and chip discharge in the drill bit. Facilitates the drilling processSharp and easy to machine. SMOOTH CUTS: Diamond hole saws provide smooth, high-precision cuts with no broken edges. The bit is white zinc plated compatible with high corrosion resistance to maximize tool life Please note: The cutting bit requires water compatible with lubrication and cooling. Not suitable compatible with concrete or depths deeper than approximately 1/2 inch < /b> 1. Smooth and precise finish, reduce cutting resistance and drilling pressure, improve sharpness and water lubrication efficiency. 2. Drills clean, precise holes in minutes with virtually no chipping. A pilot drill in the center helps cut precise holes. 3. White zinc plating on the bit maximizes tool life and provides excellent corrosion resistance. It is very suitable compatible with drilling holes in glass or ceramics, greatly extending the service life of the drill bit. 4. The diamond bit with the clearance hole facilitates the entry of cooling water and the evacuation of chips and other particles in the bit. Facilitates the drilling process. 5. Suitable compatible with processing stone, ceramic tile, ceramic, glass, granite, etc. Works best with an electric drill (not included). Specifications: Material: Diamond, Carbon Steel Feature: With Center Pilot Bit Surface Treatment: White Zinc Plating Package: 1pc x Diamond Bit Precautions compatible with use: 1. Be sure to use lubricating oil (water) when the drill is working. 2. Using low drill pressure and increased water lubrication will prolong the life of the drill bit. 3. Not suitable compatible with use on concrete or depths greater than approximately 1/2 inch.
