After about 8, maybe 9 or so 3/4" plunge cuts in 7075 aluminum, the end mill was gone. Classic rounding of intersections with non-standard material. The price will have you thinking otherwise, but don't be fooled. This one Purchase was very disappointing and I only found out after the return window closed 3 weeks ago.$30 price with $8 performance and claims to be made in the US I don't think so.Lazy online shopping finally got me !
