China Tungsten Carbide Bar Peeling Insert Hard Alloy Cutting for Centerless Lathe Steel Rod Manufacturer, Suppliers
Product Description
Product Overview
Our Tungsten Carbide Bar Peeling Inserts are precision-engineered cutting tools designed specifically for centerless lathe operations in steel rod processing. Manufactured from premium-grade tungsten carbide (WC-Co) raw materials, these inserts deliver exceptional hardness, wear resistance, and toughness — ensuring consistent high-quality surface finishes and extended tool life even under the most demanding production conditions.
Whether you are processing carbon steel, alloy steel, stainless steel, or non-ferrous metal rods, our bar peeling inserts provide the reliability and performance you need to maximize productivity and reduce per-unit production costs.
Key Features & Advantages
1Premium Material
- Manufactured from 100% virgin tungsten carbide powder with controlled grain size
- Cobalt binder content optimized for balance of hardness and toughness
- Hardness: HRA 89-92 (depending on grade)
- Transverse Rupture Strength: ≥ 2200 N/mm²
2Precision Manufacturing
- CNC ground to tight tolerances (±0.005mm on critical dimensions)
- Mirror-polished cutting edges for reduced friction and improved surface finish
- Consistent geometry across every insert for predictable machining performance
- 100% dimensional inspection before shipment
3Exceptional Wear Resistance
- Advanced sintering process ensures uniform microstructure
- Resists abrasive wear, adhesive wear, and crater wear
- Maintains sharp cutting edges 3-5 times longer than high-speed steel (HSS) tools
- Reduces tool change frequency and machine downtime
4Versatile Application
- Suitable for peeling, turning, and sizing operations on centerless lathes
- Compatible with various steel grades: carbon steel, alloy steel, tool steel, stainless steel
- Works effectively on non-ferrous metals: copper, aluminum, brass, bronze
- Ideal for both wet and dry machining conditions
5Cost-Effective Solution
- Longer tool life reduces tooling costs per piece
- Higher cutting speeds increase machine productivity
- Consistent quality reduces scrap rates and rework
- Lower total cost of ownership compared to imported premium brands
