Product Features：The diamond hole cutter is made from high-hardness industrial-grade carbon steel. A high-quality diamond coating improves sharpness and cutting speed, while a center-positioning drill bit enhances cutting accuracy. The combination of these features results in smooth, fast, and precise cuts
Precision and Efficiency: This diamond core drill bit comes with a denser diamond coating and more acute fluted edges. It has the ability to bore out precise flat-bottomed holes on smooth materials like tiles, ceramics, glass, marble, and granite, and it does so without causing any chipping or damage
User - Friendly: Start by using the tile hole saw that has a positioning drill bit attached for the purpose of positioning the hole. Once the positioning is done, take out the positioning drill bit. During the drilling process, it is necessary to continuously add water. Then, use the tile hole saw directly to cut the hole
Package: Each hole saw has two removable pilot drills (1 diamond-tipped pilot drill, 1 center pilot drill) and a hex wrench
【Note】After each cut, it is essential to promptly remove the debris inside the hole saw before proceeding to the next use
