Solid-Carbide Substrate, OK Hard Coating
OK Hard coating is standard — no uncoated option — across all 12 catalogue sizes, matched to hardened-steel machining.
4-Flute Vibration-Proof Geometry
A fixed 4-flute square-end geometry under the catalogue's own vibration-proof designation, for chatter suppression in hardened-steel milling.
Hardened-Steel Specialist
Rated for ISO H (hardened steel) material class only — the "High Hardness" (HP) line name signals this end mill is not intended for general soft-steel work.
