At Toolman Special Steels, high-speed steel has been part of our story since the beginning. What started as a trading division for HSS cutting tools in 1957 has evolved into a global manufacturing operation supplying premium HSS grades to customers across India, USA, Europe, Japan, Turkey and Southeast Asia. 

The Evolution of High-Speed Steel

The development of HSS fundamentally changed machining history.

Before high-speed steel, cutting tools lost hardness rapidly at elevated temperatures, limiting cutting speeds and productivity. Early breakthroughs in alloyed tool steels around the beginning of the 20th century allowed machining speeds to increase dramatically, reshaping industrial manufacturing worldwide. 

Today, high-speed steels are broadly classified into:

Types of High-Speed Steel

HSS Category	Characteristics	Common Grades
Molybdenum-based HSS	Balanced toughness, wear resistance, cost efficiency	M2, M3, M7
Cobalt HSS	Improved red hardness and heat resistance	M35, M42
Tungsten-based HSS	Excellent hot hardness and edge retention	T1, T4, T15, T42

Values and classifications are based on Toolman’s HSS product range. 

Toolman’s High-Speed Steel Portfolio

Toolman manufactures and supplies a wide range of HSS grades for global tooling applications.

Toolman High-Speed Steel Grades

Grade Family	Grades Available
M-Series HSS	M2, M3, M7, M35, M42
Tungsten HSS	T1, T4, T15, T42
Specialty Grades	ABC III

These grades are supplied for applications involving:

• Cutting tools 
• Metalworking tools 
• Woodworking tools 
• Gear cutting 
• Broaching 
• Precision machining

HSS Grade Selector

Choosing the right HSS grade depends on the application, cutting conditions, material being machined, and performance priority.

Requirement	Recommended Grade
General-purpose cutting tools	M2
Better wear resistance than M2	M3
Toughness for shock-prone tools	M7
Better red hardness and wear resistance	M35
High-performance machining of hard materials	M42
Tungsten-based edge retention	T1
Extreme hot hardness and wear resistance	T15
Advanced high-performance machining	T42
High-load or custom tooling applications	ABC III

Why High-Speed Steel Still Matters

There’s a common misconception that carbide has replaced HSS entirely. In reality, modern manufacturing still relies heavily on HSS because it offers something carbide struggles with: balanced toughness.

Carbide delivers exceptional hardness, but it can also be brittle. HSS, on the other hand, offers:

• Better shock resistance 
• Easier regrinding and reshaping 
• Lower tooling cost 
• Greater versatility across varied cutting environments 

That’s why HSS remains widely used for:

• Drill bits 
• End mills 
• Reamers 
• Taps and dies 
• Gear cutters 
• Broaches 
• Saw blades 

In many real-world machining environments – especially where interrupted cuts or variable loading exist – HSS still delivers outstanding value.

Common Applications of High-Speed Steel

• Hand tools 
• Precision knives 
• Rolling mill rolls 
• Industrial tooling systems 
• Precision drill bits made from HSS 
• Machined HSS bars 
• CNC machining environment 
• Industrial cutting tools

Manufacturing High-Speed Steel: Why Process Matters

Producing high-speed steel is not just about alloy chemistry – it’s equally about metallurgical control.

• Uniform carbide distribution 
• Structural cleanliness 
• Consistent hardness 
• Reliable machinability 

Our infrastructure supports the production of high-speed steels for demanding industrial environments worldwide. 

High-Speed Steel vs Carbide

Choosing between HSS and carbide depends on application priorities.

Property	High-Speed Steel	Carbide
Toughness	Higher	Lower
Brittleness	Lower	Higher
Regrindability	Easier	More difficult
Cost	Lower	Higher
High-Speed Cutting	Good	Excellent
Shock Resistance	Better	Limited

For many manufacturers, the ideal tooling strategy often combines both materials depending on cutting conditions and cost priorities.

Why Global Buyers Choose Toolman as a High-Speed Steel Manufacturer

Over the years, Toolman has built long-term relationships with tooling manufacturers and OEMs who value consistency as much as chemistry.

Global buyers choose Toolman because we provide:

• A broad portfolio of HSS grades 
• Export-ready supply formats 
• Consistent metallurgy 
• Technical guidance for tooling applications 
• Reliable logistics and documentation 

Our experience in high-speed steels spans more than six decades – and that metallurgical legacy continues to shape our manufacturing approach today.

Closing Note

Machining technology may continue to evolve, but the fundamentals remain the same: cutting tools still require strength, heat resistance, wear resistance and reliability. High-speed steel continues to deliver that balance better than almost any other tooling material.

At Toolman Special Steels, we remain committed to manufacturing HSS grades that meet the demands of modern machining – from conventional workshops to advanced CNC production environments worldwide.
