Bought this milling cutter for milling. In the week I've had it, it's cut sheets from 1/2" CDX plywood, curved jigs cut from 1/2" birch plywood, grooves for hidden joist hangers cut from 4x6 old-growth cedar and is still just about as it is sharp as unpacked. All cuts were very clean, full depth on plywood cuts and 1/8 inch deep on solid. I will definitely buy it again.
