Product Description
4 Flutes Left Spiral Tungsten Solid Carbide Reamer With Blue Nano Coating
Core Advantages:
- Left-Spiral Flute Design (40° helix) - Forces chips forward for optimal blind-hole performance
- Blue Nano Titanium Coating - 30% harder than conventional TiN with superior heat resistance (1,100°C)
- 4-Flute Balanced Geometry - Delivers IT6 tolerance (Ra 0.2μm) with vibration-dampening stability
- Ultra-Fine Carbide Substrate - 0.5μm grain structure for edge durability in hardened materials
Features:
Blind Hole Optimization
- Chip-Drag Prevention: Left spiral actively pulls chips out of deep cavities
- 15° Primary Relief: Eliminates workpiece rubbing at hole bottom
Coating Advantages
- Low Friction Coefficient (μ=0.3) reduces cutting forces by 20%
- Oxidation Resistance outperforms standard TiN in stainless steels
Precision Features
- Laser-Measured Runout <0.003mm
- Dual Margin Design enhances hole straightness (>5×D depth)
Special Applications:
- Medical - Bone screw holes with <0.005mm deviation
- Aerospace - Turbine disk cooling holes (anti-galling edge prep)
- Automotive - Fuel injector bodies requiring µ-level finishes
