【High Quality】 This diamond drill bit is made of high-quality steel with a diamond powder coating for corrosion resistance. The thickened diamond coating on top provides excellent cutting resistance for smooth, high-precision cuts without the need for hemming, ensuring optimal drilling results.

【11 Size Diamond Hole Saw】 This diamond hole saw set includes 11 different bits to meet your various needs. It includes the following diameters: 5mm, 6mm, 8mm, 10mm, 12mm, 20mm, 25mm, 30mm, 35mm, 40mm, and 50mm. Made of high-strength 45 steel, the integrated steel frame makes these diamond bits more durable.

【Adjustable Hole Saw Drill Guide】 Mounting guide with suction cup base. The maximum opening length of the plates is 4 to 83 mm, large enough to fit all saw sizes. The removable ball bearings come in two models (fixed bearings 3 or 4) – simply flip the board over. 【Ergonomic Design】 The large safety hole on the drill bit allows cooling water to enter, preventing chips and other particles from entering the drill hole, ensuring even drilling and facilitating the drilling process. A small hole allows debris to be removed with a screwdriver when it becomes trapped in the hole saw, providing a perfect experience. 【Wide Application】 This diamond hole saw can be used to remove rings from glass, marble, tile, ceramic, PVC, or other materials. When the diamond drill bit is running, continue adding water and reduce the speed. Hole Saw Guide Specification: 11 Size Diamond Drill Bits Material: High-quality steel, diamond dust coating
