Bekken, buiten voor 3-klem 5" boorkop

Snug fit on my 5" 3-jaw chuck with barely any runout once I seated them. Took me a minute to confirm I needed outside rather than inside jaws, so definitely check your old ones first. Gripping stock for boring operations feels way more solid now.

Ordered these outside jaws to replace the worn set on my mini lathe and they bolted right on with no shimming needed. The gripping surface grabs stock cleanly, way less slipping than my old jaws. Just double-check you actually need outside versus inside before ordering, like the listing says.

Snug fit on my 5" 3-jaw chuck with barely any runout once I seated them. Turning the outside of a small aluminum cylinder finally came out concentric instead of tapered. Just double-check which jaw style you need before ordering, the inside versus outside thing tripped me up at first.
