1/2" VARIABLE FLUTE CARBIDE ROUGHING ENDMILL

I bought one of these to give it a shot at some point down the road. When I finally got around to trying it, I was in a bit of a pinch trying to get a hot job out for a local customer that was a few pieces of 304SS. I had a VERY non-rigid set-up due to the shape of the part and the amount of time I had. I ended up at 900 RPM, 0.375” DOC (per the part), 0.010” FPT and .025” radial-engagement. This thing just kept taking more and more feed, I would have tried more radial-engagement but I only had one cutter and just enough stock to finish the job. It left a nice finish for a roughing endmill considering 304SS and the less than rigid set-up I had going on. I got the few parts out and was very happy. Then my customer came back and said they want 45 more pcs. and 25 more pcs. of the same part in a different length, all in the next day or two. I immediately ordered some more tooling, but to my very pleasant surprise the 1 cutter I put in the machine finished all three of those jobs. I ended up using one of Lakeshores variable 5-flute cutters to do the rest of the clean-up (14MTMX5S). Evidently, this is some SERIOUS carbide.
