ER Collet Set for Milling Machines and Lathes

ER collets have a wide gripping range (about .040 inch) and provide a fast, easy and accurate way of holding end mills, fly cutters, saw mandrels and drill bits in milling machine spindles. When used in a lathe, they hold stock more accurately and have a better grip than chucks, and thin-wall tubes can be gripped without distortion. They're quick to set up and can be used at high speed. Our ER25 collet set includes a precision ground shank and 'snap-in' collets with compression nut and spanner for easy tightening, plus custom molded case.

R8 shank fits MicroLux #84630 Mini Milling Machine, and other mini lathes and mills. (Check tool holder capacity and shank size before ordering.)

Harper U. ★★★★★

Picked up a set for my milling projects, and the .040-inch gripping range is a lifesaver for swapping between end mills and drills without constant re-tooling. I've run it through several aluminum and steel cuts, and the accuracy is noticeably better than my old collets.

Leo W. ★★★★★

The grip range on these collets is impressive; I can switch between different end mill sizes without swapping holders. It took less than a minute to seat my first tool and run a test pass.

Harper ★★★★★

Swapped out my old solid holders for these and the .040-inch gripping range makes a real difference when I need to switch between different shank sizes mid-job. They seat quickly and hold end mills firmly without any wobble during cuts.
