Diamond Glass Hole Opener for Ultimate Solution of Glass Drilling Needs
The Diamond Glass Hole Opener is designed to be used with a hand drill or cordless drill. It does not have a center drill, so you need to tilt the hole opener at 45°, slow down the drill speed, and slowly touch the glass to create a crescent groove. The crescent groove serves as a positioning function. After that, you can start the vertical drill. Circular swinging cuts faster to speed up the hole opening process.
One of the best things about the Diamond Glass Hole Opener is that it is easy to use. Simply follow the instructions provided above, and you'll be able to create perfectly round holes in glass and other materials in no time. It is important to remember to not cut too fast during the hole opening process and to continue to add water to cool the hole opener. This will ensure that it lasts longer and produces better results.
