(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: Cut through stucco wall - Worked surprisingly well. I used it to cut through stucco/concrete exterior wall. I wanted to install a round 4-1/8 receptacle for a security light and this cut the perfect size hole. Not deep enough to cut through completely, but got me most of the way there. I just used a 1/8 masonry drill bit to drill around and finally, a couple taps with a hammer to break through. Had this been about 1/4 deeper inside, it definitely would’ve cut through completely. Go slow and use a spray bottle to keep it wet. I cut two holes in a wall about 1-1/4 deep, still plenty of life left. Review: Helped me remove a headless screw - I used this to remove a screw on which the head had rusted and crumbled. It was used to mount a shower slide bar and we didn't have more replacement tile, so I needed to get the screw out. I measured the broken screw's mate's diameter and determined that these 6mm hole saws would work. Using the hole saw, I drilled through the cement backerboard around the screw. I went pretty slow as I wasn't able to use any water to cool or lubricate the saw. Probably took about 10-15 minutes. The screw came loose just as the hole saw broke, and lodged in the hole. After removing the problem screw, I just used a larger-diameter screw to bite into the inside of the broken hole saw and pulled it out. I was pretty hard on the saw, putting a good amount of force on the drill, and for the price I would consider this a consumable and a good tradeoff for getting the job done. I can't speak for other use cases but for mine, it worked very well and the price meant my DIY repair was a good value. ## 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.
