High Speed Steel versus Carbide in Metal Cutting - Why HSS
HSS – High Speed Steels – Still Playing a Very Significant Role in Metal Cutting. High Speed Steel is a high carbon tool steel, containing a large dose of tungsten. A typical HSS composition is18% tungsten, 4% Chromium, 1% Vanadium, 0.7% carbon and the rest, Iron. HSS tools have a harness of 62-64 Rc.
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.

• Speed equals 80 surface feet per minute in 100 Brinell hardness material and the speed should be reduced 10 surface feet per minute for each additional 50 points Brinell hardness. • Feed and speed rates should be reduced up to 45-50‰ when drilling holes deeper than 4 drill diameters.

M42 is a cobalt-molybdenum super high speed steel that is known for its superior red-hardness in comparison to M2 steel. The addition of cobalt to the composition of M42 provides a good balance of toughness and hardness. M42 high speed steel may be heat treated to (68 – 70 HRC).

However, the end user still needs to be cautious to not exceed the limitations of the high-speed steel. Coating hardness is measured in HV (hardness in Vickers). Heat — treat M2 as the base drills before coating would measure 880 HV (65RC).

Feb 18, 2020 · High-speed steel (HSS) drill bits are a type of tough, durable drill bit traditionally used for high-volume production drilling. Production drilling involves fast, repetitive drilling with few — if any — breaks between tasks. Many manufacturers exclusively produce drill bits that employ HSS construction because they are so versatile.
