We primarily machine Stainless steel on our BT40 machines, and in the effort of improving tool life, we primarily use short-length toolholders. Our ER collet holders are all the shortest ones we can find, and we even have some of the "superigid" ones where the collet is recessed into the taper section.
I think this has helped tool life a bit, but we are struggling with chip evacuation because it is so difficult to get coolant to spray on the tools when they barely protrude from the spindle nose. And these coolant delivery issues are causing tool breakages when we can't flush the chips away well enough. All of which is eliminating the intended benefits of short gage length holders.
I see videos on youtube with people using very long toolholders and they seem to be fine... Am I making things more difficult for myself than necessary with using these stubby toolholders?
