Description
Widin's carbide roughing end mill is optimized for aggressive material removal in aluminium and non-ferrous alloys. Built to deliver fast metal removal without sacrificing control, this tool is ideal for roughing pockets, slots, and large features. With dimensions of 20 mm x 55 mm, it fits standard toolholders and compact milling setups for quick changeovers.
The 38° helix angle minimizes vibration and enhances chip evacuation, helping you maintain steady cuts and reduce built-up edge. Crafted from carbide, the end mill offers exceptional hardness and wear resistance, delivering long tool life and reliable performance even in demanding machining conditions.
- 38° Helix for Smooth Cutting: The 38-degree helix reduces chatter and promotes efficient chip evacuation, supporting consistent material removal and longer tool life.
- Carbide Construction for Durability: High-hardness carbide delivers superior wear resistance, ensuring reliable performance and extended tool life in tough aluminium and non-ferrous work.
- Optimized Roughing for Aluminium & Non-Ferrous: Designed for high material removal rates, enabling aggressive roughing with fewer passes and easier setup.
With these design features, this end mill helps you accelerate your milling workflow, reduce downtime, and achieve consistent, ready-for-finishing surfaces. You gain dependable performance in challenging alloys, longer tool life under heavy use, and the flexibility to tackle larger, roughing operations with confidence.
