Left Hand Spiral End Mill 3 Flute CNC Milling Bits High Speed For Smooth Finishing

Left-Spiral Right-Cutting CNC End Mill For Smooth Finishing 3 Flutes For Aluminum

Introduction:

The Left-Spiral Right-Cutting CNC End Mill is a high-performance milling tool designed for precision machining, especially optimized for aluminum and other non-ferrous materials. Its unique left-hand helix with right-cutting direction ensures smooth chip evacuation, reduced vibration, and superior surface finishes. With 3 flutes for balanced material removal and efficiency, this end mill is ideal for CNC machining, aerospace, automotive, and mold-making applications.

Features:

✔ Left-Helix Right-Cut Design – Enhances chip evacuation, minimizes edge buildup, and improves cutting stability.
✔ 3-Flute Geometry – Optimized for aluminum, offering faster feed rates while maintaining precision.
✔ High-Speed Performance – Made from high-grade carbide for durability and heat resistance.
✔ Smooth Finishing – Produces low roughness (Ra) surfaces, reducing the need for secondary finishing.
✔ Anti-Vibration & Reduced Tool Wear – The left-spiral design decreases harmonics, extending tool life.

Advantages Over Competitors

✅ Efficient Chip Removal – Prevents clogging in deep pockets and high-speed operations.
✅ Superior Surface Quality – Ideal for fine detailing and high-tolerance machining.
✅ Versatile Application – Works excellently on aluminum, brass, plastics, and composites.
✅ CNC & Manual Compatibility – Suitable for both CNC mills and manual milling machines.
