35mm Diamond Hole Saw - Diamond Drill Bit with Center Drill Bit - Diamond Hole Saw for Tiles, Glass, Ceramics, Marble and Limestone - RTGPT

(Precise Positioning): Unlike traditional glass hole saws, our hole saw features a positioning system. A central pilot drill bit facilitates precise positioning, ensures the drill bit doesn't slip or jam, and makes drilling accurate holes easier.
(Cutting Effect): The surface diamond coating is sintered. The cutting edge contains diamond particles from the inside out, guaranteeing a consistent cutting edge. Its low cutting resistance and stable drilling allow for smooth and precise cutting without edge breakage, for optimal results.
(High-Quality Material): The diamond hole saw is made of industrial-grade, high-strength carbon steel with a nickel-plated surface, which effectively prevents corrosion and rust. The diamond coating on the drill bit is thick and uniform, improving its wear resistance and lifespan.
(Anti-chip design): Our diamond drill bit features a side groove design, facilitating water cooling and ensuring the removal of chips and other particles during drilling. The process is more convenient and efficient.
(Wide application): This diamond drill bit is compatible with cordless drills, lithium-ion drills, and bench drills. It is widely used for drilling precise holes in glass, ceramics, porcelain, tiles, limestone, slate, marble, pumice stone, and fiberglass.
