Product Introduction

This high-performance carbide step chamfer reamer combines 6-flute precision, AlTiN coating, and internal coolant channels to deliver superior hole finishing in hardened steels (HRC 45+), stainless steel, and exotic alloys. Designed for CNC machining centers, it performs chamfering and reaming in a single pass, reducing cycle times while maintaining H6-H7 tolerances (±0.01mm).

Key Features
  • AlTiN Coated Carbide Construction
    Advanced AlTiN coating (4-5µm) withstands 900°C for extended tool life
    Micro-grain carbide substrate (K10 grade) for wear resistance in hardened materials
  • 6-Flute Spiral Design
    30°-45° helix angle for optimal chip evacuation
    Balanced cutting edges reduce vibration in high-speed machining
  • Internal Coolant System
    2-4 precision coolant holes (Ø1.2mm) for direct cutting-edge lubrication
    Supports high-pressure coolant (70+ bar) for deep-hole applications
  • Integrated Step Chamfer Geometry
    Chamfer angle: 45°-90° (customizable)
    Eliminates secondary operations (drilling + chamfering in one tool)
  • High-Precision Ground Edges
    H6-H7 tolerance compliance (ISO 286)
    Mirror-like finishes (Ra ≤0.4µm)
Performance Advantages
50% Longer Tool Life vs. TiN-coated reamers in hardened steel
30% Faster Cycle Times - Combines chamfering + reaming
Chip-Free Machining - Spiral flutes + coolant prevent clogging
Deep-Hole Ready - Stable up to 5xD depth
Industrial Applications
  • Aerospace
    Turbine disk bolt holes (Inconel 718)
    Landing gear bearing bores
  • Automotive
    Transmission gear shafts (HRC 50+)
    High-pressure fuel injectors
  • Medical
    Surgical implant threading (Ti-6Al-4V)
    Bone screw pilot holes
  • Mold & Die
    Core/cavity finishing (H13/P20 steel)
    Ejector pin chamfering
