Frequently Asked Questions
Q: Is it safe to leave a tool clamped in the collet overnight? A: No, leaving a collet under drawbar tension for extended periods can cause it to stick in the spindle taper, making it difficult to remove.
Q: What size drawbar thread does this use? A: All standard R-8 collets utilize a 7/16-20 internal thread to mate with the machine’s drawbar.
