Collet Chuck, ER-11, Straight Shank, Professional Grade

This ER-11 collet chuck straight shank tool holder is a great tool for supporting small end mills and engravers. It is made of 20CrMnTi alloy steel and is balanced to 18,000 RPM. The maximum runout is 0.0003" (0.0076 mm).

ER-11 collets have a range of 1/32" to 1/4" (0.5 to 7.0 mm). The overall length is 3.457" (88 mm) and the width at the nut is 0.748" (19 mm).

*Collet must be assembled into a collet chuck nut before inserting into the collet chuck.

Chris 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.
