Collet Chuck, ER-25, 2MT

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.

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.

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.
