Luomorgo 75mm/3 inch Diamond Hole Saw, 1.1 inch Cutting Depth Diamond Diamond Drill Bits for Glass Ceramic Marble Porcelain Tile Granite Quartz Gemstone

A fraction the price of big box stores name brands and in my opinion work just as well for DIY. For professional repeated use probably not, but I've used mine a few times and still does the job even thru porcelain and ceramic.You can use the tilt technique, or I prefer to make a jig in a piece of 3/4 plywood with a same sized wood hole saw first, then carefully clamp it to my work. If you can't clamp it, have someone hold it while you get it started. A jig can slide a bit on glossy tile, but with practice it's pretty easy to master. You could probably stick on some rubber cement between the two or a self stick rubber pad to keep it from sliding around. You only need the jig to get the full circular cut started, then it's easy to hold in place without the jig in your way. More accurate than tilt method.I use higher speed on tilt method to get cut going. Seems to move around less than on slow speed. Use a little water to cut easier and save the diamond edge.With both methods, I slightly tilt saw from side to side and in circular motion as I'm cutting to keep it cutting thru. Makes a nice clean hole. Be careful of sharp cut edges.

I bought this drill to cut holes in an office desk I bought at a furniture warehouse, so that I could thread my computer wires in from down below the desk, where my outlets are. It's a good product for the price. Worked as well as expected. I'd recommend this product.

Good coating!!! DurableWhy did you pick this product vs others?:Looked ok

Great drill bits for drilling holes in glass for a craft project. They worked very well and held up through quite a bit of use.

This is a quality drill bit for the money . I couldn’t believe how expensive these bits are in the big box store and I refused to pay $80 when i only needed to drill 1 hole through tiles. The speed and drill accuracy of this bit blew my mind ! It cut through the 2x4 tile like it was butter !

Good value cuts fast.

This is not 3 inches. This is 75mm. They are NOT equivalent and you should not sell them as such. I took the listing at face value when I ordered it, and the hole is just barely too small for the project intended. Thankfully I didn't cut into the final material with it first.Sell metric, or sell imperial, don't market as both.
