Steel-shank indexable boring bar from RMC Tooling, machined in the United States. Ground shank, standard indexable geometry, and a rigid clamping system sized to the bar diameter — the combination that keeps chatter down at the depths where boring bars usually give up.

Sized by minimum bore, so start there: pick the largest bar diameter your bore will clear. Every clamp, lock pin, seat and screw in this bar is a stocked RMC service part, listed below.
