110mm Diamond Hole Saw with Central Guide Drill Bit for Tiles, Glass, Ceramics and Marble – Precise and Fast Cutting

Superior Quality: Our glass hole saw with positioning pilot drill is made of high-quality diamond, a solid hardened steel body, and the surface is nickel-plated, ensuring high hardness, rust protection, corrosion protection, and long-lasting robustness and strength. 【Precise Positioning Pilot Drill Design】 Each tile hole saw is equipped with a removable positioning pilot drill. The pilot drill bit's cutting head is also diamond-coated, making it sharper and more durable, and effectively securing the hole saw's position for quick hole cutting. [Size] Cutting diameter: 110 mm, cutting depth: 35 mm, overall length: 70 mm, triangular shank diameter: 10 mm. [Sharp and Clean Holes] These diamond drill bits with a thicker diamond coating create a cleaner groove edge and can cut precise, flat-bottomed holes without chipping on smooth surfaces such as ceramic tiles, glass, marble, granite, terrazzo, etc. Cutting depth up to 30 mm. [Easy to Use] Operation is simple and requires no special guide tools. Use the tile hole saw with the pilot drill bit to position the hole, remove the pilot drill bit after positioning, and then cut the hole directly with the tile hole saw. Note: Remember to add water or coolant during the cutting process to prolong the life of the diamond hole saw.
