4 Cutting Edge Carbide Reamer Without Coating Finishing Tool for
Perfect Holes in Metal Components
Product introduction:
Our 4-Flute Solid Carbide Reamer represents the pinnacle of hole finishing technology, delivering
unmatched precision for your most demanding machining applications.
Manufactured from premium micro-grain tungsten carbide and offered
without coatings, this reamer produces exceptionally smooth, accurately sized holes with tight tolerances. The four-flute design provides optimal balance between cutting efficiency and surface
finish quality, making it ideal for high-precision CNC machining, aerospace components, and automotive
part manufacturing.
Features:
✔ 4-Flute Uncoated Design - Delivers superior surface finishes (Ra 0.2-0.4μm typical)
✔ Precision Ground Carbide - Japanese-grade substrate ensures consistent performance
✔ Multiple Tolerance Classes - Available in H6, H7, H8 for different precision requirements
✔ Optimized Geometry - Special relief angles prevent work hardening in stainless steels
✔ Straight/Spiral Flute Options - Choose based on material and application needs
✔ Through-Coolant Capable - Optional internal coolant channels for heat-sensitive operations
Advantages:
✅ Unmatched Hole Accuracy - Maintains ±0.005mm diameter tolerance
✅ Extended Tool Life - Carbide construction provides 3-5× longer life vs HSS reamers
✅ Burr-Free Results - Precision ground edges produce clean hole exits
✅ Reduced Chatter - 4-flute design ensures exceptional stability
✅ Material-Specific Performance - Geometry optimized for different metal types
Applications:
✓ Aluminum & Non-Ferrous Alloys (6061, 7075, brass, bronze)
✓ Stainless Steels (303, 304, 316, 17-4PH)
✓ Tool & Die Steels (pre-hardened up to HRC 40)
✓ Cast Iron & Powdered Metals
