HRC55 2-Flute Long Neck Ball Nose End Mill
Le présent HRC55 2-flute solid carbide long-neck ball nose end mill for steel est conçu pour 3D contouring and deep-cavity mold finishing. Reduced-neck geometry provides sidewall clearance for recessed curves, fine details and hard-to-reach surfaces.
Caractéristiques principales
01
Ball-nose geometry for precision 3D contouring and mold finishing.
02
Reduced-neck clearance for deep cavities and recessed surfaces.
03
Two-flute design supports chip evacuation in small-diameter milling.

04
HRC55 series for suitable steel and pre-hardened mold-steel applications.
05
Multiple ball radii and neck lengths, with custom options available.
