Review on Milling Cutter Rotary 3 175Mm 3 17512Mm by Mark Loebis

You get what you pay for! Terrible sanding geometry (Fine sanding was clean and shiny but geometry was far away) 1 and 1.5mm are unsuitable when you need to endure tolerances or finishes. If you have a steady hand, a diamond circle with a 10x loupe can get a flute going. The first cut I received was negative. If the primary grinding cut the material, the secondary grinding would undoubtedly erase/smudge/abrade the cut surface. The radii of virtually all of them were not symmetrical and did not match their respective diameters. They're great for engraving, but don't expect a clean finish that doesn't require extra work.
