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-hardness 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.
