I have an application where I want to do some milling at the bottom of a pocket. I need a 1/4" diameter cutter that can reach >3/4" into a 1/4" slot, but I don't need more than about .100" for the length of cut and I'd like something that is both ridged and durable.
What I'd really like is a 1/4" HSS end mill on a 1/4" shank with only about 1/2" of cut, which would result in most of the stick out being full cross section which should help strength and rigidity. But for some reason all the mills I find with those dimensions (other than the cheap 1 star chinesium on Amazon) are carbide.
Is there some reason what I'm looking for isn't made? Is what I'm looking for know by some other name?
