I mostly cut acrylic. I like and use a single flute, 3/16" diameter HSS end milll (Amana 15621). I tend to get around 2000 inches of cutting out of it. New bits start out cutting clean & quiet, then cut quality gradually decreases until it starts struggling… chattering and melting material. This might not be simple to answer, but could a change to a carbide end mill significantly increase life expectancy? The HSS mills are around $8 each so it’s no big deal to burn through them, but I’d pay more if I could hold the cut quality for longer and get more use out of it.
Has anybody been through this - any opinions to share?
PS - I’ve been thinking a lot about adding the Beaver HDZ. I don’t do much aluminum but I do some & it’ll help there, but i also fell like the rigidity will help a lot with acrylic too, and maybe this will also help with tool life no matter what I use. Yes? Talk me into it
