【Vacuum Brazed Diamond Technology】High-density diamonds are brazed more firmly to the matrix and provide longer service life. #35/50 diamond is sharp to drill holes in the ceramic and porelain tiles.Diamond grit:#35/40
【Easy to use】There is wax inside the drill bit. No need for additional water cooling and increases drilling speed.
【Application】Suitable for all tiles, marble, artificial stone, granite, stoneware and quartz.Hex Shank,used on hand drill, bench drill, etc. Recommended RPM: 2000-5000RPM.Please do not use hammer drill model.
【Attention】Hold the drill bit at a 45 degree angle until the bit begins to penetrate the material, then raise the bit to the vertical position and continue.Applying too much pressure won't make the drill faster, but it will generate too much heat, reducing efficiency and longevity.
