Mgtgbao 1 Inch (25Mm) Dry Diamond Core Drill Bits, Vacuum Brazed Diamond Hole Saw Kit For Porcelain Ceramic Tile Granite Marble Stone Brick Glass With 5/8-11 Thread Review

First thing to keep in mind with this 1-1/8 diamond tipped hole saw is that it’s NOT a drill bit. It has a threaded shank for a 5/8-inch hub like you’d find on an angle grinder. See my video for details. The Mgtgbao hole saw is adequately crusted with industrial diamonds and is rated for quartz, marble, tile and brick. It would most likely be used by most consumers to install soap dispensers and water or electrical lines through counter tops or shower valve holes through tile. As you can see in

Having been talked into replacing three countertops in the kitchen and bathroom with granite I have been gathering all the tools needed for such a job. This is but one of many.These diamond coated bits and hole saws are just the thing for making clean holes in granite. They are well made and one heck of a good value for what you are getting. These will fit on most angle grinders (including mine) but sometimes a drill is needed and you need an arbor to convert the 5/8-11 threads into something…

Model: 3/8 Inch (10mm) Dry Diamond Core Drill BitsPerfect for creating drainage holes in ceramic and concrete planters. The bore was completely filled with wax including part of the threaded section. This didn't allow the threads of my grinder to engage all the way. But after removing all the wax the bit performs exactly as expected.

I used this bit to scratch small marks at the bottom of some beer glasses (on the inside) to give the carbonation nucleation sites, to make a bigger head and get good foam propogation. This bit worked great! Beer in these glasses now have a more persistent head that aids in the enjoyment of the beverage, creating a better nose and aroma.

Nicely made, fits standard angle grinder shaft, wide wrench fitting, heavy diamond coating, nice storage case. Fast shipping! Great value.
