35mm Diamond Hole Saw, Diamond Drill Bit with Center Guide, Diamond Coated Tile Hole Saw for Cutting Glass, Tile, Ceramic, Marble and Limestone

【PRECISE POSITIONING】: Compared to traditional glass hole saws, our hole saws are equipped with positioning aids. The centering tip allows for precise positioning, prevents the bit from slipping or jamming, and ensures accurate drilling results. 【CUTTING EFFECT】: The diamond coating is produced using a sintering process. The cutting edge contains diamond particles from the inside out, ensuring permanent sharpness. Low cutting resistance and stable drilling allow for smooth, high-precision cuts without chipping, for optimal results. 【HIGH-QUALITY MATERIAL】: Diamond hole saws are made of high-strength industrial-grade carbon steel with a nickel-plated surface, which effectively protects against corrosion and rust. The thick, uniform diamond coating of the tip improves wear resistance and extends the life of the hole saw. 【OPTIMAL ANTI-BLOWOUT DESIGN】: The cutting head of our diamond drill bit is equipped with a cavity with side vents. This facilitates the flow of cooling water and ensures the removal of chips and other particles from the hole during operation. This makes drilling more convenient and efficient.【VERSATILE APPLICATION】: The diamond drill bit is suitable for cordless drills, lithium-ion drills, and benchtop drills. It is widely used for drilling precise holes in glass, ceramic, porcelain, tile, limestone, slate, marble, pumice, and fiberglass.
