Cemented carbide tools

Cemented carbides are composite materials made by sintering hard-phase carbides of refractory metals (such as WC, TiC, and TaC) with metallic binders (such as Co, Ni, and Fe) using powder metallurgy techniques. They represent the most widely used and versatile classic substrate in the cutting tool industry, combining high hardness, high strength, and excellent impact resistance. Cemented carbides can cover the entire range of machining operations—from roughing to semi-finishing—and form a core complementary system alongside metal ceramics as the primary substrate for high-end cutting tools. They also serve as an important supporting substrate strategy for ceramic cutting tool manufacturers.

Cemented carbides are composite materials made by sintering hard-phase carbides of refractory metals (such as WC, TiC, and TaC) with metallic binders (such as Co, Ni, and Fe) using powder metallurgy techniques. They represent the most widely used and versatile classic substrate in the cutting tool industry, combining high hardness, high strength, and excellent impact resistance. Cemented carbides can handle a full range of machining operations—from roughing to semi-finishing—and form a core complementary system alongside metal ceramics as the primary substrate for high-end cutting tools. They also serve as an important supporting substrate strategy for ceramic cutting tool manufacturers.

Relying on their advantages of high toughness, impact resistance, and mature processing technology, cemented carbide cutting tools are the “universal cutting tools” for mechanical manufacturing. Their applications span across all industries and all machining processes, with the following key scenarios:

1. Rough machining / Heavy cutting: Turning, milling, and drilling of carbon steel, alloy steel, cast iron, and non-ferrous metals—such as rough machining of machine tool beds, large shaft components, and mold blanks.

2. Intermittent Cutting: For machining workpieces with grooves and steps—such as gears, splined shafts, and flanges—this method offers impact resistance, thereby preventing chipping or cracking of the cutting edge.

3. General Semi-Finishing: Batch processing of common mechanical parts, balancing efficiency and precision, suitable for small-to-medium batch production with diverse product varieties.

4. Rough machining of difficult-to-machine materials: Rough machining of titanium alloys, high-temperature alloys, and stainless steels (with coatings), leaving sufficient stock for subsequent finish machining.

5. Non-standard tool manufacturing: Due to their excellent machinability (suitable for grinding and welding), these tools are widely used in the production of customized, non-standard cutting tools tailored to specific workpiece machining requirements.
