Milling tools monoblock \ Solid carbide mills for machining stainless steel
Solid carbide HPC end mill ( Milling cutter design standard Company
standard )
4 fl utes, ULTRA MS-coated

ULTRA Typ Z HB HA
VHM VA HPC
MS 4 35°/38° 45°
Application:  high-performance ULTRA MS layer Ident. No. 320–327
HPC end mill with uneven helical and uneven pitch  with edge protection chamfer
for rough machining and fi nish machining of stain-  defi ned cutting edge rounding
less steel, titanium alloy, nickel and copper alloys.  centre cutting
The uneven helical pitch means that vibrations on
the tool are reduced, which results in outstanding  Ident. No. 320–327: HB straight shank Ident. No. 330–337
fi nished surfaces, while, at the same time, feed rates  Ident. No. 330–337: HA straight shank
and cutting depths can be increased.
Advantage:
Execution:  rough machining and fi nishing with just one tool
 ultra-fi ne grain cemented carbide  optimum suitability for trochoidal milling
 with uneven helical and cutter distribution  HPC geometry for maximum feed rates and running
(35/38°) smoothness
 with clearance  suitable for large cutting depths
