Company Overview
Kedel Tools, a leading Chinese carbide manufacturer, produces carbide rotary burrs—critical tools for precision shaping, deburring, and finishing across industries. These burrs leverage advanced materials and design for superior performance.
1. Materials of Carbide Rotary Burrs
| Component | Properties |
|---|---|
| Tungsten Carbide (WC) | – Near-diamond hardness (Mohs scale), enabling cutting of tough materials (steel, cast iron). – High wear resistance for prolonged tool life. |
| Cobalt (Co, Binder) | – Enhances toughness, bonding WC particles for durability. – Improves resistance to chipping under high-stress machining. |
Key Benefit: WC-Co alloy ensures exceptional hardness + durability, outperforming HSS (high-speed steel) in harsh environments.
2. Structure of Carbide Rotary Burrs
| Structural Element | Function & Design |
|---|---|
| Cutting Edges | – Precision-ground for aggressive material removal (e.g., shaping metal surfaces). – Available in diverse geometries (cylindrical, ball-nosed, tree-shaped) for specific tasks (deburring, finishing). |
| Shank | – Cylindrical design for compatibility with drills, grinders, or CNC machines. – Ensures stable rotation and minimal vibration during operation. |
| Body Geometry | – Optimized for versatility: – Cylindrical: Flat surface machining. – Ball-nosed: Contoured surface finishing. – Tree-shaped: Heavy material removal (e.g., casting cleanup). |
3. Advantages of Tungsten Carbide Rotary Burrs
Core Strengths (Bullet List)
- Hardness & Durability
- Withstand high-speed machining of steel, stainless steel, and non-ferrous metals without rapid wear.
- Ideal for high-volume production (e.g., automotive manufacturing).
- Versatility
- Perform shaping, deburring, grinding, and finishing on both flat and contoured surfaces.
- Compatible with materials like aluminum, brass, and even composites.
- Efficiency
- High material removal rate (faster stock removal than HSS tools) reduces machining time.
- Maintain tight dimensional tolerances (±0.01mm) for precision parts.
- Cost-Effectiveness
- Longer tool life (2–3x vs. HSS) lowers replacement costs and downtime.
- Superior surface finish (Ra ≤ 0.8 μm) reduces post-machining polishing needs.
Comparison with Alternatives (Table)
| Feature | Carbide Rotary Burrs | HSS Burrs |
|---|---|---|
| Hardness | Near-diamond (Mohs ~9) | Mohs ~6 (softer, faster wear) |
| Wear Resistance | Excellent (WC-Co alloy) | Moderate (prone to chipping) |
| Material Removal Rate | High (aggressive cutting) | Low (slower stock removal) |
| Tool Life | 2–3x longer | Shorter (frequent replacement) |
4. Application Examples
- Automotive: Deburring engine blocks, shaping transmission components.
- Aerospace: Finishing turbine blades, precision hole machining.
- Metal Fabrication: Edge rounding, weld bead removal.
Conclusion
Kedel Tools’ carbide rotary burrs, with their WC-Co material composition and precision-engineered structure, deliver unmatched performance in hardness, versatility, and cost-efficiency. Their design caters to diverse industrial needs, making them a top choice for precision machining tasks.
