Description
Conventional high
speed steel Standard tool material for most
common applications Used for the manufacturing of cutting tools such as twist drills,
end mills and taps.
5% cobalt grade of
high speed steel High-heat resistance, especially
suited for roughing or when coolant
insufficient Cobalt alloyed, tungsten-molybdenum high speed steel possessing
high hardness, excellent cutting properties, high-red hardness and
good toughness.
8% cobalt grade of
high speed steel Increased heat resistance and
hardness, suitable for
difficult-to-machine materials Available for applications that require a strong resistance to softening at
elevated cutting temperatures. The ability of the steel to maintain its “red-
hot hardness” is provided by the addition of cobalt. The high hot hardness
is required for machining difficult materials such as nickel-base, titanium
and highly alloyed steel.
HSSE Premium grade of
high speed steel Wide range of machine taps Vanadium grade gives high wear resistance and toughness for most
tapping applications.
PM-HSSE V3 Powdered
metallurgy -
vanadium grade of
high speed steel Materials with hardness
up to 40 HRC
Difficult-to-machine materials
eg. stainless steels PM-HSS V3 for higher performance tools, incorporates very fine
and uniform grain structure allowing a high hardness to be achieved,
whilst maintaining good toughness.
Powdered
metallurgy - 8%
Cobalt grade of high
speed steel Materials with hardness
up to 45 HRC The addition of cobalt provides this material with the ability to maintain
its strength and hardness level when exposed to extremely high cutting
temperatures. This makes PM-HSS Co suitable for heavy duty tapping,
in materials such as high alloyed steels to non-ferrous metals like
Ni-base alloys & Ti-alloys.
Powdered
metallurgy - 11%
Cobalt grade of high
speed steel Special applications, requiring very
high edge hardness.
Cutting tools with the appropriate
geometry can be applied to
workpiece materials with hardness
up to 55 HRC An excellent bridge material between high speed steel and carbide.
SPM offers very high red hardness, wear resistance and the highest
compressive strength of any high speed steel.
VHM Sub-micron grade of
solid Carbide
(ISO K15-K30) Tapping hardened steel Ultra fine grain type (0.8µm) with maximum toughness &
high hardness, therefore especially recommended for rotating
tools to machine hardened parts.
VHM Sub-micron grade of
solid Carbide
(ISO K40) Sutton standard grade for endmills
& drills Ultra fine grain type (0.6µm) offers the ideal combination of hardness &
toughness for high performance drilling & general milling applications
VHM-ULTRA Sub-micron grade of
solid Carbide
(ISO K40-K50) High performance grade for endmills Ultra fine grain type (0.5µm) offers the best wear resistance for high
performance milling applications.
