Size: Drilling diameter: 75 mm; Shank diameter: 10 mm; Total length: 75.7 mm; Package contents: 1 diamond drill bit (comes with a packaging box). Material: The head of this glass drill bit is made of diamond, which has very high hardness and can easily cut various materials; its excellent wear resistance gives the diamond hole saw a long service life; at the same time, the diamond exhibits good stability during the cutting process, providing a smooth and precise cut, resulting in better cutting quality and accuracy; the drill bit body is forged from carbon steel and is not easily deformed, helping you to open holes easily. Features: Our diamond core drill bits have a thicker diamond coating that makes the groove edges sharper, allowing you to easily make high-precision cuts on smooth surfaces without cracking. The side of the drill bit is designed with a large chip removal hole to ensure the drilling tool can efficiently remove debris during cutting and guarantee smooth, continuous operation. Application: This universal hole saw is suitable for most electric drills on the market, so you can use it to drill holes in glass, tile, marble, ceramic, porcelain, fiberglass, slate, or light stone, meeting most drilling needs in your work or daily life. Note: Depending on the material being cut and the work requirements, please choose the appropriate rotation speed, maintain a stable grip and smooth cutting force, and avoid excessive pressure to prevent damage or jamming of the tool. Additionally, for some continuous drilling operations that require extended work time, please use a suitable coolant or lubricant to help reduce temperatures and prolong the tool's lifespan.
