D3-D20mm 6 Flute Left Hand Spiral Reamer AlTiCrN Coated Carbide H5-H7 Tolerance

Product introduction:

This 6-flute left-hand spiral carbide reamer features an advanced AlTiCrN coating and precision-ground geometry for superior hole finishing in hardened steels (HRC 45+), stainless steel, and high-temperature alloys. Designed for CNC machining centers and lathes, it delivers mirror finishes (Ra ≤0.2µm) and tight H5-H7 tolerances in a single pass.

Features:

AlTiCrN Coated Carbide

  • Withstands 1,000°C for high-speed machining

  • 30% longer tool life vs. TiN/TiAlN coatings in abrasive materials

  • Low friction coefficient reduces built-up edge

6-Flute Left-Hand Spiral Design

  • Left-hand helix (20°-30°) pulls chips upward, preventing workpiece scratching

  • Balanced 6-flute geometry ensures vibration-free operation at high RPM

Ultra-Precise Tolerance (H5-H7)

  • Ground cutting edges (±0.005mm runout)

  • Ideal for precision bores (e.g., hydraulic valves, bearing seats)

Coolant Compatibility

  • Through-tool coolant holes (2-4 channels, Ø1.0mm)

  • Supports MQL and high-pressure coolant (up to 70 bar)

Robust Shank Options

  • Cylindrical/Weldon flat shank (DIN 6535)

  • HSK/BT interfaces available for CNC automation

  • Hybrid Taper/Straight Sections

  • Laser-Marked Depth Indicators

  • Special Shanks (ER, HSK, CAT, BT)

Applications:

Aerospace

  • Turbine blade root holes (Inconel 718)

  • Landing gear bearing bores

Automotive

  • Transmission gear shafts (HRC 50+)

  • Fuel injection nozzles

Medical & Energy

  • Surgical implant bores (Ti-6Al-4V)

  • Valve bodies in oil/gas equipment
