ER-16 collets have a major diameter of 0.67" (17.0 mm) and a length of 1.08" (27.5 mm). They have a clamping range of 1/32" to 3/8" (0.5 mm to 10.0 mm).

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

Customer Reviews (4.6 / 5 · 5 reviews)

Violet T. ★★★★★

The tool steel finish feels solid in the hand, and the 0.67-inch diameter seats perfectly in my holder without any wobble. Just used the 1/8" size for a light milling pass and the grip held firm all the way through.

Leo ★★★★★

The gripping range is spot on for my smaller end mills, and the tool steel feels solid in the hand. These collets run true with barely any runout on my mill.

Riley ★★★★★

Swapped my old set for these ER-16s and the 1/32" to 3/8" range covers everything I chuck up. The tool steel feels dense and the 0.67" body seats squarely every time, runout is basically nil.
