ER-16 collets are 17 mm (0.67") maximum diameter and 27.5 mm (1.08") long. They have a clamping range of 0.5—7 mm (0.020—0.276").

ER collets are made from high grade tool steel, hardened and ground to close tolerance. Kerf cuts allow the collet to expand and contract as needed within the specific clamping range to securely hold the tool or workpiece.

Chris' Tips

Chris Chris' Tips
This shows the sizes of all the ER collets we carry.

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.
