SHDIATOOL 4 - Inch Diamond Grinding Wheel for Granite Marble Iron Steel Masonry Cup Grinding Disc 30/40 Grit, Dry/Wet Use, Fits 7/8 Inch Arbor

Hollowed out stones for pots and a large boulder for a birdbath. Chews through hard sandstone and even worked well on rhyolite (harder than granite.) Method involved parallel cutting with diamond wheel, knocking out remaining stone fins, and then finishing by shaping and smoothing with this disc. You can actually carve stone with this "flying saucer" profile. Highly recommended.

Was hesitant for price but works great. Use this on carbide teeth for a forestry mulcher cutter head on my excavator. Regular grinding disc's wouldn't touch them. This takes mere seconds on each one. After a few uses its still holding up well. Highly recommended.

works great for grinding cracks

Used for various stone shaping jobs while building summer kitchen. Everything from pre-shaping bluestone before using a bull nosing bit, to smoothing a curved brick wall before pargeing. Would buy again!

Bought this to grind out some ceramic tile to fit a propane fire pit insert. Didn’t chip or crack the tile! Used with a corded Makita angle grinder. Match made in heaven.

The diamond blade cut off embedded hardened tapcons like butter! Made a very tough job easy. My regular grinder blades were taking forever to cut these tapcons so I switched to the diamond blade. Done 30 bolts in 15 minutes. Barely any wear on blade. Great quality for price!
