<p> 【Precise Positioning】: Compared to traditional glass hole saws, our hole saw features a positioning aid. A pilot drill bit in the center helps you position accurately, ensuring the drill bit doesn't slip or jam, and helping you drill precise holes. 【Cutting Effect】: The diamond surface coating undergoes a sintering process. The cutting edge contains diamond particles from the inside out, guaranteeing it remains sharp. Low cutting resistance and stable drilling allow for smooth, high-precision cutting without edge breakage, ensuring optimal cutting results. 【High-Quality Material】: The diamond hole saw is made of industrial-grade, high-strength carbon steel with a nickel-plated surface, effectively preventing corrosion and rust. The drill bit's diamond surface coating is thick and uniform, enhancing wear resistance and extending the hole saw's lifespan. 【Chip Removal Design】: Our diamond drill bit features a notched design with side clearance holes, which facilitates water cooling and ensures that chips and other particles are expelled from the hole during drilling. The process is more convenient and efficient. 【Wide Application】: The diamond drill bit is suitable for cordless drills, lithium-ion drills, and bench drills. It is widely used for cutting precise holes in glass, ceramics, porcelain, tile, limestone, slate, marble, pumice stone, and fiberglass.</p>
