(Rotate and cut faster) Open a crescent socket on one side of the hole (the crescent socket plays a role in positioning), and the electric drill starts to work correctly. Do not drill too fast during the drilling process, you need to continue to add water to cool the hole opener Note Light shooting and different displays may cause the color of the items in the picture to be slightly different from the real object. Due to manual measurement, please allow error of 1-3 mm. Excellent & Sincere Service Jamiikury wants our customers to be happy and satisfied.

Review: Etremely recomended. Cuts through tile like butter. Very easy to use, high speed at the start since it does not come with a pilot hole drill bit. Buy with confidence and guranteed. Review: This hole saw works well. I needed to cut a shower valve hole in a 12 x 12 tile and it did it nicely. I ended up cutting a guide block out of wood, then clamping it to the tile. I submerged the tile and guide block in a concrete mixing pan and filled it with water and had no trouble cutting the hole. It took about 5 minutes to cut at slow speed on a cordless drill. Recommended. ## Features - SMALL DRILL BIT: Hole diameter: 100mm(4"),total length: 56mm(2.2").Package includes 1 pcs 100mm diamond hole saw drill. - HIGH QUALITY: Diamond ceramic hole saw are made of industrial grade carbon steel and have a nickel-plated coating to resist corrosion. - LARGE CLEARANCE HOLE: These glass hole saw set along the drill bit facilitate the entrance of cooling water and escape of chips and other particles from drilling.
