H20 STUPR 3W Interchangeable Head for CNC Turning

H20 STUPR 3W — interchangeable head, 1-1/4" head diameter. Made in the USA by RMC Tooling.

Interchangeable boring head from RMC Tooling, machined in the United States. The head mounts on a matching RMC bar, so one bar covers a whole family of geometries and you only buy the cutting end.

The retention system is not interchangeable between families: heads with a W suffix use SM-series seats with LP-series pins, and heads without it use ICSN/IDSN seats with NL-series pins. The exact parts for this head are listed below.
