Tungsten Carbide End Mills: Precision, Durability, and Performance in Modern Machining

Technical Specifications of Tungsten Carbide End Mills

Shanghai Easydrill’s end mills are designed for maximum performance in demanding environments. Key features include:

• Material:

• Carbide Grade: Ultra-fine grain tungsten carbide (WC) with 6–10% cobalt binder for optimal hardness (92–94 HRA) and fracture resistance.

• Coatings:

• TiAlN (Titanium Aluminum Nitride): Enhances heat resistance (up to 900°C) for high-speed machining.

• AlCrN (Aluminum Chromium Nitride): Ideal for non-ferrous materials and dry machining.

• DLC (Diamond-Like Carbon): Reduces friction in abrasive composites and plastics.

• Flute Types:

• 2–3 Flutes: High chip evacuation for aluminum, plastics, and soft metals.

• 4–6 Flutes: Superior finish and stability in steel, titanium, and hardened alloys.

• Variable Helix: Minimizes vibration and chatter in challenging materials.

• Diameter Range: 0.5mm to 25mm, supporting micro-machining to heavy-duty operations.

• Helix Angles:

• 30°–35°: For hard metals (e.g., stainless steel, Inconel).

• 45°–55°: For soft materials and aggressive material removal.

• Shank Types: Straight, Weldon, or HSK/BT shanks for CNC machine compatibility.

• Speed Recommendations:

• Aluminum: 800–2,500 RPM

• Steel: 300–600 RPM

• Titanium/Inconel: 100–250 RPM

• Compatible Materials: Metals (hardened steel, aluminum, titanium), composites, plastics, and ceramics.

Applications of Tungsten Carbide End Mills

These tools excel in industries requiring precision and endurance:

1. Aerospace: Machine turbine blades, engine components, and lightweight alloys like Inconel and titanium.

2. Automotive: Produce high-tolerance parts such as gearboxes, pistons, and EV battery housings.

3. Medical Devices: Craft intricate surgical instruments, implants, and prosthetics from biocompatible materials.

4. Mold & Die Making: Create detailed cavities and cores in hardened tool steel with ball-nose and corner-radius end mills.

5. Electronics: Mill micro-components for circuit boards and connectors with ultra-fine carbide end mills.

6. Energy Sector: Machine components for wind turbines, oil rigs, and nuclear reactors under extreme conditions.

Advantages of End Mills

Tungsten carbide end mills deliver unmatched benefits:

• Extended Tool Life: 5–10x longer lifespan than HSS, reducing downtime and tooling costs.

• Higher Cutting Speeds: Achieve faster machining cycles without sacrificing precision.

• Superior Hardness: Withstand abrasive materials and high-temperature environments.

• Enhanced Surface Finish: Minimize post-processing with smooth, burr-free results.

• Versatility: Available in square, ball-nose, corner-radius, and roughing designs for diverse tasks.

• Cost Efficiency: Lower long-term costs despite a higher initial investment.
