ER16 Collets

ER16 collets in 20 metric sizes from 0.5 to 10.5 mm and 12 inch sizes from 1/16" to 13/32", plus 27 DNA 16 collets and two ER16 collet sets (10-piece inch, 10-piece metric). An ER16 collet is 27.5 mm (1.08") long with a 17 mm (.67") outside diameter.

Metric collets are named by the shank range they hold, for example ER16 5-6mm, 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.

DNA 16 collets are DNA (Dead Nuts Accurate) collets for small tools. They hold the shank with more rigidity and accuracy than a standard ER collet, with 0.0002" runout, and they fit your ER16 holders. They run from 0.2 mm up to 10 mm, including exact-size collets for 1/8", 3/16", 1/4" and 3/8" shanks.

ER16 collets fit the ER16 holders on BT Collet Chucks (BT30, BT40), HSK Collet Chucks (HSK63F, HSK40E, HSK50E), ISO Collet Chucks (ISO20) and Straight Shank Collet Chucks & Extensions. ER16 slotted, mini and dust seal nuts are on Collet Nuts, and ER16 internal dust seals on Dust Seals & Covers. All ER sizes and collet sets: Collets.
