OK guys, I'm looking for good long lasting endmills to cut keyways in a 4020 Fadal VMC. I've tried 3 flute, 4flute, HSS and carbide. I think the carbide 4 flutes worked the best. I'm cutting 1045 and 1144, no tool steels. Plenty of coolant, I've set the cutters to take a chip load of between .001 and .002, but the problem is I want endmills that will last. I'm not sure what brand to use, I do know pretty much all tool sales reps are worthless as far as customer support. They come and go without suppling soulutions just very high tooling bills. I think it would be cheaper to buy good quality endmills that last veses cheaper endmills with more tool changes. Do you guys have any recomendations on endmill brands and styles for longer tool life? Of course we would like to buy American, but it seems like the market is flooded with import junk. Any information will be greatly appreciated.-Thanks
