65 mm diamond hole saw with centering guide, tile hole saw with diamond coating, diamond core drill for glass, tiles, ceramics, marble, granite

【Superior Quality】 Our glass hole saw with positioning drill bit is made of high-quality diamond and a robust, hardened steel body. The nickel plating on the surface ensures high hardness, rust and corrosion resistance, robustness, and durability.

【Precise Positioning Drill Bit Design】 Each hole saw is equipped with a removable positioning drill bit. The drill bit's cutting head is also diamond-coated, making it sharper and more durable. This effectively fixes the hole saw's drilling position for fast drilling. [Size] Cutting diameter: 65 mm, cutting depth: 30 mm, overall length: 70 mm, triangular shank diameter: 9.5 mm. [Sharp and clean holes] These diamond drill bits with a thicker diamond coating create a sharper groove edge, allowing for precise, shallow holes without chipping in smooth surfaces such as ceramic tiles, glass, marble, granite, etc. (including terrazzo). Cutting depth up to 30 mm. [Easy to use] Operation is simple and requires no special guide tools. Position the hole using the hole saw and pilot drill, remove the pilot drill after positioning, and drill the hole directly with the hole saw. Note: Remember to add water or coolant during the cutting process to extend the life of the diamond hole saw. 【Package Contents】 Includes 1 diamond hole saw, 1 pilot drill, and 1 wrench. Each diamond hole saw set is individually packaged in a plastic box, and each drill bit is also oiled (to prevent rust).
