Heres a good question for all you machinests ..Where do you buy your endmills ?...I am looking for a good site that sells new inexpensive fair to good quality endmills..I have been cutting mostly aluminum and been using Niagra HSS Double end for the 3/16 and smaller cutters ..these are costing me over $20 a peice and i know my local supplyer isnt marking them up that much ..Is it recommended that I use 2 0r 4 flute and should i use carbide ... will that give much more extended Life ?..Lately I have been cutting thicker aluminum .37 thick and like to use a 1/8 toolbit on acount of radiaus..i am hoping to find longer shanks as well ..Should I add another 1/2 toolbit thickness for releif in my CAM programing when cutting out thicker parts ?
What Brands do you guys like to use ?
