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:

• Aerospace component finishing (landing gear, turbine disks)

• Automotive transmission systems (gear housings, valve bodies)

• Hydraulic/pneumatic components (manifolds, cylinder blocks)

• Medical device manufacturing (implant connection points)

• Mold/die maintenance (ejector systems, guide bushings)

• Energy sector components (valve seats, pump housings)
