حامل أداة التجويف، 3/8" عمود، خارجي MGEHR06-2

The 3/8" shank fits perfectly in my tool post, and the insert indexing is spot-on — no fiddling to get the groove depth consistent. I've been using it for parting off stainless steel, and it holds up without any chatter.

The precision clamping on this holder is spot on—my inserts seat firmly with zero wiggle, and the 3/8" shank fits my toolpost perfectly. Parting off and grooving have been smooth and chatter-free right out of the box.

Clamped my first workpiece with it and the finish on the grooving pass came out cleaner than I expected—no chatter at all. The 3/8 shank fits my toolpost perfectly without any wobble. Definitely getting consistent results now for external grooves.
