While I don't have multiple thread designations on my collets and other holders (all are 7/16-20UNF), I really need to cut down the long hex on my drawbar. It's one of those extra long ones made so you can change tools without retracting the quill. What a waste. I have never needed to do that and even if I did the R8 shanks combined with whatever tool is on the "business end" is usually so long that if I didn't retract the quill I'd have to lower the knee.
The shortening will get done the next time I need to tilt the head because I do not have enough ceiling height above the spindle to pull the drawbar out if the head is in the normal orientation.
