I'm looking for a 1 inch, 2-flute,straight-flute carbide endmill source...preferably an off-the-shelf grind as opposed to a custom. My shop mainly runs plastic jobs in sheet form that run from @ .060" to .250" max (depending on the job), and the tool will be milling the finish profile on the edges so it must have a good plastic-relief profile. We usually use 1.00" Putnam HSS tools that work just fine, but they don['t hold an edge very long so we wind up pulling the tool out several times a run for resharpening. This is a pain in the neck and a waste of time that we'd like to eliminate if possible.
What I need: Either a solid or a carbide-tipped version with @ 1/2" minimum flute length. A stainless shank brazed-on tip version would be cheaper, obviously, but beggars can't be choosy and since I've mostly struck out in my attempts to find such a critter I'll take what I can get.
What I don't need: Insert-style tooling (not sharp enough), 1.00" Garr endmills (far too much regrinding necessary to be useful), and spiral grinds. Most of our jobs use vacuum fixtures to hold the parts down which works great but vacuum can fail with tooling profiles that "lift" the parts so that is why I need straight flutes.
We can do some regrinding to suit our needs, but not too much because we don't want to spend more time on the grinder than at the machine. As far as price goes it's not much of a problem at this point because most of our jobs don't use tools this large; this one's only for a couple of jobs that we do that only run @ 6-10 times a year so we could justify spending a bit more on a given tool as long as it lasts longer than the Putnams that we have been using for years.
Thanks in advance.
Rob.
