MTVNR 16-4D Indexable Tool Holder for CNC Turning

MTVNR 16-4D — toolholder, 1" square shank, 6.0" overall length. Made in the USA by RMC Tooling.

Indexable turning toolholder from RMC Tooling, machined in the United States. The shank is ground to a qualified reference surface, so the tool goes back into the turret at the same cutting-point location every time it is swapped — no re-touching off, no lost setup.

Built for production lathes and CNC turning centers. The insert pocket, seat and clamping hardware are all standard RMC service parts, listed below, so the holder stays in service for years instead of being scrapped when a clamp screw strips.
