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)
