Izar 6644 — HSS-Co Fine-Pitch Roughing Endmill (Multi-Flute, 30° Helix, DIN 844 N-RF)

The Izar 6644 is an industrial-grade high-speed steel roughing endmill, crafted for versatile, high-efficiency metal removal. Featuring multi-flute geometry, a 30° helix, and optimized chip-breaking edges, this rougher is built to handle demanding roughing tasks in steel, stainless steel, titanium, and other hard alloys—delivering high feed rates and reduced tool wear.

Geometry & Benefits

• Cobalt-alloyed powder HSS (HSS-Co): Combines toughness and heat resistance for durability in heavy-duty roughing applications.

• Fine-pitch, multi-flute design: Maximizes material removal while maintaining tool stability and reducing vibration.

• 30° helix angle: Balances effective shearing action and steadiness during high-feed operations.

• Chip-breaking edges: Break up long chips into manageable segments, improving evacuation and reducing side forces.

• DIN 844 N-RF standard: Ensures industry-standard geometry and compatibility with tooling systems.

Typical Uses & Applications

• Rough milling in challenging materials like carbon steel, alloy steel, stainless steel, titanium alloys, and nickel-based alloys.

• Ideal for high-feed, high-material-removal operations in both general machining and heavy material removal.

• Suitable for both CNC and manual operations, especially where chip control, tool life, and throughput are critical.

• Available in both PMX and TiAlN-TOP coatings for additional wear resistance during aggressive roughing.
