What is M42 High Speed Steel?
M42 High Speed Steel is a cobalt-bearing high-speed tool steel that contains about 8% cobalt, which gives it excellent red hardness and cutting ability. This steel belongs to the HSS (High Speed Steel) family and is an upgrade over standard grades like M2 High Speed Steel.
You’ll find M42 used in precision cutting tools, drills, milling cutters, and saw blades, where maintaining sharpness at high operating temperatures is critical.
In simple terms: M42 HSS stays sharp longer, cuts harder materials, and resists heat better than conventional steels.
Key Features & Properties of M42 High Speed Steel
When you use M42 Tool Steel, you benefit from:
- High Red Hardness – retains cutting edge at temperatures up to 600°C.
- Excellent Wear Resistance – extends tool life under heavy cutting.
- Superior Toughness – reduces chipping and breakage in high-stress applications.
- Cobalt Enrichment – enhances heat resistance and hardness.
- Consistent Performance – reliable results in high-speed cutting and forming.
These properties make M42 the go-to choice for industrial tooling and precision machining.
M42 High Speed Steel vs Other Grades
- Compared to M2 Steel, M42 provides higher hardness and better hot strength, making it ideal for extreme cutting operations.
- When compared with T42 or T15, M42 offers a cost-effective alternative while maintaining superior cutting edge retention.
