Take away the guesswork. Every machinist knows alignment is half the craft.

These centering jigs are built for the 4th-axis accessory—featured on the Carvera, Carvera Air, and the new Makera Z1. Designed to slide directly over the rotary pivot, each jig holds your round stock perfectly centered for repeatable accuracy.

Ideal for precision machining of watch screws, dop sticks, gears, and other tolerance-based components, as well as jewelry applications such as rings.

Comes in a 3 pack.
