I need to bore a hole 2.5" deep in some 6061 the hole will be centered in a piece of 2.5" square stock hole diameter is 1.91" depth 2.5". I am wondering what type EM to use that would evacuate the chips the best. I have flood coolant. I have never bored anything that deep so I am not sure what to expect. Rougher or just a high helix 2 flute EM? I plan to do a helical tool path. The only thing I have on hand that will go that deep is a 2 flute insert EM but I don't think it will do well getting the chips out so I will buy something else.
Thanks Mike
