Precision CNC Collets
ER collets - by far the most widely used clamping system worldwide - are available here in a wide range of sizes, both individually or in sets, and at deeply discounted prices.

Our CNC collets and extension category is broken down into easy to navigate subcategories. Straight shanks are available in either metric or standard sizes. Individual ER precision collets come in the following sizes: ER16, ER20, ER25, ER32, ER40. We also offer high precision milling machine collets in sets that extend from an 8-piece ER11 set all the way up to a 15-piece ER40 collet set.

The spring-style collets sold here all have a runout of 0.0003149" (0.008mm) TIR. Our basic DZ Brand, ER11 8-piece set comes with a durable aluminum storage/carrying case and contains the following sizes: 1/4", 7/32", 3/16", 5/32", 1/8", 3/32", 1/16", 1/32". The 15-peice ER40 set contains collets ranging in size from 1/8" up to one inch.
