This is not what I was hoping for as I wanted to mill with a flat bottom. This creates a hump in the middle. Maybe I misread the description. just know Nevertheless it worked well.
Used with Alu 6061 and 7075 for a while, noticed a slight deterioration in the cutting quality, then within a few passes. The takeaway from this is stick with softer metals and materials and for the price they're fine, but you won't be happy with harder materials.
5/8 and 3/4 are correct but my 7/8 shank diameter was 20mm. I have an R8 20mm collet? of course not! So I ended up wasting time setting it up on the lathe to get it down to 3/4". I'm giving it 2 stars because the router ended up doing a great job on the aluminum I put it on should use, but wasted hour modifying I didn't plan the end mill so be careful.
