H24 DCLNR 5W — interchangeable head, 1.500" head diameter, 1.760" minimum bore. Made in the USA by RMC Tooling.
H-DCLNR/L Heads.
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.
These are the service parts RMC lists for this exact model — not a generic cross-reference. Availability of replacement parts varies by item.
