_ OCTAGON CUTTER
Walter Xtra·tec® octagon cutter F 4080 –
high flexibility for universal use.
The tool
–– octagon cutter with 8-edge indexable
insert
–– extremely soft cutting action due
to double positive geometry
–– integral balanced to ensure improved
running on the spindle
–– Ø 40–160 mm
–– approach angle 43°
–– hard-nickel plated surface provides
protection from corrosion and wear,
and ensures a better swarf flow
The application
Design balanced
–– for all steel and cast iron materials,
including stainless and difficult to cut
materials as well as non-ferrous metals
–– diverse machining possibilities: surface
milling, ramping, circular interpolation
milling, pocketing, chamfering
–– mainly for all mould and die manufacturers
as well as for general engineering
YOUR ADVANTAGES
–– can also be used with low-performance
machines due to positive, soft cutting
action
–– reductions in inventory costs: ideal
adaptation of the tool to various
materials from the variety of
geometries and cutting materials
–– high process reliability and efficiency
due to Tiger·tec® cutting tool materials
