Product Overview

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.

Key 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)
Performance 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: Lightweight structural components (7075-T6), cooling channel hole patterns
  • Automotive Production: EV battery housing drilling, aluminum casting machining
  • Electronics Cooling: Heat sink array drilling, server chassis ventilation holes
  • General Metalworking: Jig/fixture plate hole drilling, multi-diameter fastener holes
