I purchased this Speed Tiger IAUE for a finishing mill and it did not disappoint !! It leaves the best edge finish on aluminum our of all mills that I have tried to date (and that's a lot). This thing leaves a mirror-like finish. These are results that you would usually only expect out of high-end CNC milling machines. I did this with a CNC router !! Now granted, it's a higher end and rigid router (ShopSabre), but still nowhere near as rigid as a mill. The Speed Tiger IAUE will perform as advertised, but I am personally using a LakeShore Carbide TAS as my rougher and the ST IAUE as a finishing mill. I originally purchased the 3/8 but I now own the entire set with backups. Highly recommend this mill for aluminum work !!
