Size - Drilling diameter 55mm / 2.17"; shank diameter 9.5mm / 3/8"; shank diameter 9.5mm / 3/8"; drilling depth 35mm / 1.38"; total length 66mm / 2.6"
Material - The thickened diamond particles are permanently brazed to the cutting edge. Provide high efficiency, fast and smooth cutting, but also ensure longer working life. Metal surface painting provides oxidation and corrosion resistance.
Features - The serrated diamond drill bit increases the sharpness and opening speed. Sharper and more durable than ordinary diamond hole saws. Universal Tri-flat (triangular) shank provide tighter clamping and precise drilling and is more stable than round shank.
Applications - Widely used for cutting accurate holes on glass, ceramic, porcelain, tile, limestone, slate, marble, light stone and fiberglass. Not suitable for drilling tempered glass, plastic and wood.
Notice - Use wet or dry, use with coolant (water) for better cuts and longer life. Not suited for use on concrete or for depths beyond about 1/2". Start your hole diagonally, make a round trace and then hold drill straight. Use at low drill speeds and drill pressure.
