Product Info

Cemented carbide is the go-to material for high-performance cutting tools, offering unmatched hardness, heat resistance, and wear durability—helping industries extend tool life, improve precision, and reduce costs.

■ What Is Cemented Carbide and What Makes It Special?
Cemented carbide is made by combining ultra-hard tungsten carbide (WC) particles with cobalt (Co) as a binder. This mixture is sintered at high temperatures, resulting in a material that is both hard and tough—ideal for demanding machining applications.

Key features include:
・ Hardness approaching that of diamond
・ Excellent toughness to withstand impact and cutting force
・ Maintains hardness at high temperatures
・ Long tool life even under high-speed machining
・ Capable of cutting hardened steel, titanium, and exotic metals

■ Core Advantages That Directly Impact Tool Life
Extreme Hardness (HRA > 90)
Its super-high hardness allows cutting of hard materials without damaging the cutting edge. This leads to:
・ Fewer tool changes
・ Less machine downtime
・ Lower labor costs

■ Outstanding Wear Resistance
Cemented carbide maintains edge sharpness even under high-speed cutting conditions.
・ Prolongs tool usability
・ Reduces dimensional deviation

■ Thermal Stability at High Speeds
Cemented carbide retains hardness even under intense heat from milling or turning at high RPMs.
・ Prevents tool deformation
・ Ensures process reliability

■ Impact and Crack Resistance
When machining with unpredictable cutting forces, such as rough turning or interrupted cuts, its toughness helps prevent chipping and cracking.
・ Higher productivity
・ Reduced risk of sudden tool failure

■ Real Industrial Benefits
Cemented carbide isn’t just reliable—it delivers measurable advantages:
・ 3–10x longer tool life than high-speed steel (HSS)
・ Lower cost per part due to durability and longer cutting cycles
・ Better dimensional accuracy and reduced surface defects
・ Versatility: Suitable for soft aluminum, hardened steel, titanium, and heat-resistant alloys
・ Coolant reduction possible in dry cutting operations

■ Further Improvement Through Materials Technology
Modern advancements enhance cemented carbide’s already excellent performance:
・ Ultrafine WC grains: Sharper, longer-lasting edges
・ Additives (TiC, TaC): Boost crack and fatigue resistance
・ Advanced coatings (e.g., TiAlN, AlCrN): Improve heat and wear resistance dramatically
