Rubberflex collet question

darxtar · Nov 29, 2012

I have a piece of steel that I have to turn down. It is 0.772" in diameter. It will slip, with very little effort into a J15 (5/8" - 3/4") Rubberflex collet. The question is, is that OK to, do or should I be scrunching down the J16 (3/4" - 7/8") collet ? Thanks.

Personally, I would use the 5/8-3/4--if no pressure is needed to insert your metal. Either will do and ain't Jacobs Rubber Flex collets great!

No use the next size up the rubber has to squish some or a lot, not none, helps keep the metal fingers in line

Just don't take too heavy a cut. The blades in the collet will tip with too heavy a torque. Ask me how I know. Peter

You can't be afraid to really crank down on the hand wheel of the chuck. I've taken some borderline stoopid-heavy cuts with no issues.
