Have had some large (3/4") old carbide endmills for 40 yrs, used them only occasionally. I'm wondering if it's worth the $ to have them re-sharpened, or has the quality of carbide improved so much over the years that I'd be better off just scrapping them and buying new stuff?
I mostly mill aluminum w/ hss,but have used one recently to modify an Armstrong heavy service clamp, probably 1040 steel, 30-ish rc hardness. Was a bit of a slog!
