The collet block is 1.75" across the flats and the body is 2.7" long.

Chris' Tips

Chris' Tips
With all ER collet chucks, the collet must be snapped into the nut before placing it into the chuck. There is an eccentric ring inside the nut that engages the groove in the collet. That is what makes them self-ejecting. Tilt the collet again to remove it from the nut.
