مشبك مخرطة - 4"، 4 فكين، ذاتي التمركز

Setting up square stock on this 4-jaw chuck is surprisingly quick, and the self-centering action locks it in place with no wobble. I've been using it for octagonal workpieces and the grip feels solid even at higher speeds.

The 20mm through bore is a real plus for my longer stock, and it centers square stock dead-on without any wobble. I've only had it a week, but the grip on 3-inch pieces feels rock solid so far.

Swapped out the old 3-jaw for this 4-jaw and square stock sits dead true now, no shimming needed. The jaws grip an 80 mm octagonal piece without any wobble, and runout stayed under a thou right out of the box.
