SHDIATOOL 1/2 Inch Shank Round-Over Router Bits 12MM Radius Corner Rounding Edge-Forming Marble Granite Quartz Stone

This went through quartz without any issue. For more context, I have a Skil router that's 14 amp and 2.5 horsepower. provided a great roundover for my edges

I used this to round the corners of my sinder block pillars under my house so my vapor barrier won't tear on the edges. It needs to be installed on an angle grinder with a collet adapter though.

Good quality for the price, worked as it should profiling my granite countertops.

thought it was cheap but seems to have a lot of life left in it. grits 60. 80 120 220 and some tormek blade polish and there it is. 1hrs worth and I have a nice outside table.

Long lasting and easy to use! I used one bit to roundover two sides on over 200 cut pavers for my fire pit. I used a little water while cutting to keep the dust down. Highly recommend these bits.

Working good!

It works great for the first 6 linear feet of tile, after that chips the tile.

I had some issues edging my concrete circle. Came back in with this and it cut a very nice rounded edge where there was none before. Honestly, it surprised me how nicely it came out. You almost can't tell that I didn't edge it wet.

Big caveat, I bought specifically for machining travertine which is a very soft stone. It makes short work of this and for the price it's a real bargain. Fits in medium duty router and I found best at a medium speed of around 5000rpm. Will need some polishing to get super smooth but that's almost always the case with this style of tool. Not surprisingly on travertine, the tool has no signs of wear whatsoever.

I needed to finish a rough cut granite edge. The router bit made a nice even rounded edge that I was then able to polish.

Worked as advertised Did a very nice job on the marble

Why 2 stars it looks real good. I will not get to use it until July . Then we will see it’s value.
