I was wondering how far you typically like to have your end mills stick out beyond the collet face.
I typically set the tools in as far as possible, with the flutes starting just outside of the collet, so I have the shortest stickout possible. I do this because I am looking for the most rigid setup possible. I mill stainless almost exclusively, so I am always looking for greater rigidity.
But, the short stickout often creates challenges with getting coolant to the tool since the collet nut acts as an "umbrella" to block coolant.
I often see pictures online of endmills sticking out quite a bit from their collet or toolholder. For example, on a 3/8" endmill, I'll often see the tool sticking out 3/8" to 1/2" beyond the minimum location that I usually use. That extra stickout probably would help with coolant delivery.
In your experience, does the extra stickout make much of a difference?
