I had a heck of a time finding a drill bit in this diameter that was deep enough for our 3cm granite slab. We needed this size for a vessel sink. We cut a guide in wood and clamped it to the granite to make a straight cut. It worked perfectly and only took a few minutes. Well worth the price. The shop where we got our slab wanted $120 to make this cut!

Needed this for body spray heads. Also found it was the perfect size for delta diverter valves.The diamonds/grit is quite rough. It cut fast through thick, full body porcelain. But, with the speed and rough diamonds it chipped a lot. I cut 9 holes wet, and it barely slowed downWill definitely buy again

Worked excellent

works best in a grinder. cuts fast and clean

Attached to my angle grinder perfectly. Drilled a hole in 1” marble. I used a spray bottle to keep blade wet. And keep the dust low. Drilled a hole in about 2 min. Great bit and will definitely buy again when needed.

I used this to cut drain holes through solid surface countertop - maybe 3/5" thick? mounted it to my angle grinder, sprayed water as a lubricant and started at an angle before leveling. Still a fair amount of dust, but it moved through the material quickly.

One of the best Diamond bits I’ve ever used - it was absolutely effortless cutting through an exterior stucco wall.
