ER50 Collets

ER50 collets in 17 metric sizes from 5 to 34 mm (1 mm ranges up to 10 mm, 2 mm ranges above) and 6 inch sizes from 1/2" to 1-1/4", plus the 17-piece ER50 metric collet set. An ER50 collet is 60 mm (2.36") long with a 52 mm (2.05") outside diameter.

Metric collets are named by the shank range they hold, for example ER50 16-18mm, and inch collets by the shank size. Our ER collets are made from high-carbon bearing steel, ground and heat treated, and hand inspected, with runout (T.I.R.) averaging 0.0002". Use them with a PowerCOAT nut for the best holding power and cutting tool life.

All ER sizes and collet sets: Collets.
