Custom 2 Flute Straight Flute Carbide Step Drill for Aluminum Multi
Diameter Hole Cutting High Speed CNC Machining OEM ODM Support
Introduction:
Our custom 2-flute straight flute carbide step drill is engineered specifically for high-efficiency aluminum machining, combining precision-ground tungsten carbide with an optimized straight flute design for superior chip evacuation. This specialized tool eliminates the need for multiple drill bit changes by creating multiple hole diameters in a single operation, significantly reducing cycle times in CNC machining centers and high-volume production environments.
Features:
✔ Premium Carbide Construction
YG6X micro-grain tungsten carbide (0.5-0.8μm, 10% cobalt) for extended tool life
No coating required – maximizes sharpness for aluminum and soft metals
✔ Optimized Straight Flute Design
2-flute geometry reduces cutting forces and prevents material adhesion
High helix angle (30°-35°) for efficient chip ejection
Polished flutes minimize friction and heat buildup
✔ Multi-Diameter Step Geometry
Custom step configurations (e.g., 4mm → 6mm → 8mm in one tool)
Precision-ground edges (±0.01mm diameter tolerance)
Center-cutting capable for plunge drilling
✔ High-Speed Performance
Stable at 15,000-30,000 RPM (diameter-dependent)
Dry machining compatible (air blast recommended)
Advantages:
▶ 50% Faster Drilling vs conventional twist drills in 6061-T6 aluminum
▶ Burr-Free Hole Edges reduce secondary finishing
▶ 100K+ Hole Life in continuous production
▶ OEM/ODM Flexibility – fully customizable step profiles
Applications:
Aerospace Manufacturing
Automotive Production
