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

【Precise Positioning】: Compared with the traditional glass hole saw, our hole saw has a positioning aid. A pilot bit in the center helps you position accurately, ensures the bit does not slip or get stuck, and helps you drill precise holes.

【Cutting effect】: The surface coating diamond 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 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-elimination design】: Our drill bit Diamond adopts notch design with side clearance holes, which is convenient for cooling water and ensures 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, tile, limestone, slate, marble, pumice and fiberglass.
