Elizabeth Q. ★★★★★

Finally got this ER-25 chuck for my micro mill and the 2 Morse taper fits perfectly with no wobble. The 1/16" to 5/8" collet range covers everything I need for small parts.

Adam O. ★★★★★

I’ve been swapping collets in and out for a few weeks now, and the ER-25 range from 1/16" to 5/8" covers all my micro mill bits. The draw thread engages smoothly and holds the collet tightly without any wobble.

George ★★★★★

The 2MT shank seated perfectly in my micro mill spindle with no wobble at all, and the ER-25 collets grip evenly across the full 1/16 to 5/8 range. Runout is noticeably tighter than the chuck I was using before, which cleaned up my finish on small end mill work.
