10mm 6 Flute AlTiN Coated Step Chamfer Reamer Internal Coolant for Steel Hard Alloys

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).

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)

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

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
