Workshop and Drilling holes with an ER collet chuck
Hi all. Sort of a question, do you use your ER collet chuck in the mill to drill holes or do you put a drill chuck in? Been doing a few bits with the new mill, mainly brackets and motor mounts for the powerfeed and I am finding it easier and quicker to use the ER collet chuck to hold the drill bits rather that change to the drill chuck, one reason is the R8 arbour on the drill chuck is very tight in the spindle, it goes in easy but is a bugger to remove, so much quicker to swap collet (I have all sizes from 1mm to 20mm)
