DIAMOND HOLE SAW 35mm, Tile Hole Saw with Diamond Surface Coating for Cutting Glass, Tiles, Ceramics, Marble, Limestone

[Precise positioning]: Compared with the traditional glass hole saw, our hole saw has positioning assistance. A pilot drill bit in the center helps you position accurately, ensures that the drill bit does not slip or get stuck, and helps you drill precise holes.[Cutting Effect]: The diamond surface coating adopts sintering treatment. The cutting edge contains diamond particles from the inside out, which ensures that the cutting edge is always sharp. Low cutting resistance and stable drilling enable smooth, high-precision cutting without edge breakage for optimal cutting results. [High-quality material]: The diamond hole saw is made of industrial-grade high-strength carbon steel with nickel-plated surface, which effectively prevents corrosion and rust.The diamond surface coating of the drill bit is thick and uniform, which improves the wear resistance and service life of the hole saw.[Chip Removal Design]: Our diamond drill bit adopts a notch design with side clearance holes, which is convenient for cooling the water and ensures that chips and other particles escape from the hole during operation for drilling. The process is more convenient and efficient.[Wide application]: The diamond drill bit is suitable for cordless drills, lithium drills and bench drills. Widely used for cutting precise holes in glass, ceramic, porcelain, tile, limestone, slate, marble, pumice and fiberglass.
