S12 SVUCL 2 — boring bar, 0.750" bar diameter, 1.125" minimum bore, 10.0" overall length. Made in the USA by RMC Tooling.
-3° End Cutting Edge Angle for 7° Positive 35° Diamond VC_T Inserts.
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.
These are the service parts RMC lists for this exact model — not a generic cross-reference. Every one is stocked.
