4 Flute TiAlN Coated Carbide Step Reamer Multi Level Hole Sizing Tool for Steel Aluminum Alloys
Product introduction:
Our 4-Flute TiAlN Coated Carbide Step Reamer revolutionizes precision hole finishing with its innovative multi-diameter design. This advanced cutting tool combines multiple reaming diameters in a single operation, delivering unmatched efficiency for complex machining applications. The TiAlN (Titanium Aluminum Nitride) coating provides extreme heat resistance (up to 900°C/1652°F) and reduced friction, making it ideal for high-performance CNC machining of steels, aluminum alloys, and exotic materials.
Features:
✔ 4-Flute Precision Geometry - Optimized balance between material removal rate and surface finish quality
✔ TiAlN Coated Carbide - Provides 3-5× longer tool life versus uncoated tools in hard materials
✔ Multi-Diameter Steps - Single tool performs multiple hole sizing operations simultaneously
✔ Precision Ground Cutting Edges - Maintains ±0.005mm diameter tolerance across all steps
✔ Through-Coolant Ready - Optional internal coolant channels for heat-intensive applications
✔ Special Edge Preparation - Prevents work hardening in stainless steels and nickel alloys
Advantages:
✅ Process Consolidation - Combines multiple finishing operations in one tool path
✅ Exceptional Surface Finish - Achieves Ra 0.1-0.3μm surface quality
✅ Reduced Cycle Times - Eliminates multiple tool changes and setups
✅ Extended Tool Life - TiAlN coating withstands abrasive and high-temp applications
✅ Improved Dimensional Accuracy - Maintains tight tolerances across all step levels
Applications:
- Automotive transmission systems (gear housings, valve bodies)
