TERMS
 M1- "HSS" is used for making drills
that will be used in a wide variety of applications.
M1 has some of the increased red-hardness properties
of M2, is less susceptible to shock, and has
"flex" capabilities generally favored
for general purpose work.
- M2
- "HSS" is the standard material used
for all ICS HSS cutting tools. M2 has good red-hardness
and retains its cutting edge longer than other
general purpose high speed steels, not as shock
resistant or as flexible as other HSS grades
with less tungsten. Generally favored for high
production machine work.
- M7
- "HSS" is used for making heavier
construction drills that can be used for portable
drilling of hard sheet metal alloys. Generally
favored for work in Aircraft plants where flexibility
and extended drill life are equally important.
- M50
- "HSS" is used for making drills
that will be used for portable drilling and
where breakage is a problem due to flexing the
drill. Does not have the red-headness of other
grades of HSS with tungsten. Generally favored
for Hardware and Contractor use, although they
are also sold for industrial uses.
- M35
- "5% COBALT" is only used by ICS
for making tool bits. It has some of the increased
red-hardness properties of M42, and is not quite
so susceptible to shock.
- M42
- "SUPER COBALT" is the standard cobalt
material used for all ICS cobalt cutting tools.
It has excellent resistance to abrasion and
very good red-hardness for working difficult
materials.
TOOL DATA: Reference
and Documentation
- Tungsten
Note
- Generally speaking, a cutting tool made of
high speed steel containing the element tungsten
will possess the very desirable property of
"red-hardness". This enables tools
to cut at a dull red heat (up to 1000° F) without
loss of hardness or rapid dulling of cutting
edge. Cobalt high speed steel will exhibit even
greater red-hardness and wear resistance.
- Super
HSS Note
- The term "SUPER HSS" is not definitive
and can mean almost anything that one wants
it to mean from ordinary M50 to High Cobalt
material.
