160mm diamond hole saw, drill bit for glass, porcelain, granite and marble, accessory for electric drill, drill bit for ceramics, cutting diameter

Quality: This 160 mm diamond hole saw is made of high-strength 45# steel, offering superior wear resistance and durability compared to standard steel. Cutting diameter: 28 mm; cutting depth: less than 20 mm; shank diameter: 10 mm. Cutting Edge Thickness: The diamond grit layer on the cutting edge of this glass drill bit is approximately 2 mm thick—twice that of ordinary diamond hole saws (which are typically only 1 mm thick). The diamond grit and cutting head are bonded using Laiwei's proprietary brazing technology. The result is a stronger, more durable, and sharper drill bit. This ensures smoother cuts and produces holes with a cleaner finish. Wide range of applications: These porcelain drill bits are widely used for drilling holes in glass, ceramics, tiles, granite, limestone, marble, and various other materials. Heat dissipation holes: The body of this ceramic drill bit features strategically placed holes designed to accelerate heat dissipation. It is essential to note that using water to keep the work area wet during drilling is imperative to ensure a perfectly finished hole. This precaution also helps extend the life of the drill bit.
