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