Solid Carbide Reamers

Key Features：
1. Full Carbide Construction：
– Substrate: High-density tungsten carbide with optimized cobalt content (6–10%) for exceptional hardness (1,800–2,200 HV) and fracture resistance.
– Micro-Grain Structure: Ultra-fine carbide grains (0.4–0.8 µm) ensure sharp cutting edges and prolonged tool life.

2. Advanced Geometry
– Flute Design: 4–8 flutes (straight or helical) for balanced chip evacuation and reduced vibration.
– Cutting Edges: Precision-ground edges with minimal runout (±0.003 mm) for uniform material removal.
– Lead Angles: 1°–5° chamfered leads for smooth entry and exit, minimizing burrs.

3. Coating Technology
– PVD Coatings: TiAlN, AlCrN, or DLC (Diamond-Like Carbon) coatings (2–4 µm) for reduced friction, heat resistance (up to 1,000°C), and anti-adhesion properties.
– Specialized Options: Custom coatings for abrasive composites or corrosive environments.

4. Coolant Integration
– Through-Tool Coolant: Internal coolant channels ensure efficient lubrication and chip flushing in deep-hole applications (up to 10× diameter).

5. Versatile Applications
– Materials: Steel, stainless steel, aluminum, titanium, Inconel, hardened steels (up to 65 HRC), and composites.
– Operations: Finish reaming, semi-finishing, and high-precision hole sizing (IT6–IT8 tolerances).

Benefits：
– Ultra-Precise Holes: Achieve tight tolerances (H7/H8) and superior surface finishes (Ra ≤ 0.8 µm).
– Extended Tool Life: Carbide substrate and coatings resist wear, reducing tool changes by 3–8x vs. HSS reamers.
– High Productivity: Optimized for high-speed machining (up to 120 m/min in aluminum) and stable feed rates.
– Reduced Deflection: Solid carbide construction minimizes tool flex for consistent hole geometry in deep or small-diameter applications.
– Cost Efficiency: Lower per-hole machining costs through extended lifespan and reduced scrap rates.

Available Configurations:
– Diameter Range: Ø1–30 mm (standard) or custom sizes (down to Ø0.5 mm for micro-reaming).
– Shank Types: Straight, Weldon, or HSK/BT-compatible shanks with coolant-through options.
– Specialized Designs:
– Helical Flute: For improved chip evacuation in blind holes.
– Adjustable Reamers: Micrometer-adjustable heads for fine tolerance compensation.
– Carbide-Tipped:*Hybrid designs for cost-sensitive applications.

Quality Assurance:
– Precision Grinding: CNC-ground edges ensure concentricity ≤ 0.005 mm and diameter tolerance ±0.002 mm.
– Dynamic Balancing: G1.0 or better for vibration-free operation at high RPM.
– Certifications: ISO 9001 compliant, with full material traceability and batch testing reports.

Packaging & Logistics:
– Protective Packaging: Individually wrapped in anti-corrosion foam or rigid plastic cases.
– Bulk Orders: Custom kits with labeled compartments for easy inventory management.
– Lead Time: Standard sizes in stock; custom tools delivered in 3–5 weeks.

Industry Applications:
– Aerospace: Fuel system components, turbine blade cooling holes, and CFRP composite structures.
– Medical: Implant bores, surgical instrument pivot holes, and micro-fluidic channels.
– Automotive: Engine cylinder honing, transmission shaft bores, and EV motor housings.
– Mold & Die: EDM electrode guide holes and precision mold cavities.

Solid Carbide Reamers are the ultimate solution for high-accuracy hole finishing, combining cutting-edge materials, coatings, and geometries to meet the strictest industrial standards. Whether machining exotic alloys, hardened steels, or delicate composites, these tools deliver unmatched performance and reliability.
