Step Tungsten Carbide End Mill 4 Flutes Forming CNC Milling Cutter For Aerospace

Step Tungsten Carbide End Mill 4 Flutes Forming CNC Milling Cutter For Aerospace

Introduction:

Our precision Step Tungsten Carbide End Mill with 4 flutes is specifically engineered for aerospace component manufacturing. This high-performance forming cutter features an advanced step design that enables simultaneous roughing and finishing operations in titanium alloys (Ti-6Al-4V), Inconel, and aerospace-grade aluminum. Manufactured from ultra-fine grain tungsten carbide with micro-grain structure, this tool delivers exceptional accuracy (±0.005mm) and surface finishes (Ra 0.2-0.4μm) critical for flight components.

Features:

• Special step geometry for efficient material removal and fine finishing

• 4-flute design optimized for vibration-free machining

• Aerospace-grade micro-grain carbide substrate (8% cobalt)

• TiAlN/AlCrN coating options for heat resistance (up to 900°C)

• Precision ground cutting edges with <0.003mm runout

• Available in diameters from 3mm to 16mm

• Custom lengths and neck designs available

Advantages:

✓ 30% faster metal removal than standard end mills
✓ Extended tool life - 4X longer than conventional carbide tools
✓ Reduced machining time by combining operations
✓ Excellent chip evacuation in deep pocket milling
✓ Maintains dimensional accuracy in thin-wall structures

Applications:

• Turbine blade root forms and fir-tree slots

• Structural component pockets and contours

• Wing spar machining

• Landing gear components

• Engine mount interfaces

• Avionics housing features
