An engineered carbide end mill designed for machinists tackling deep cavities and tight corners. The 4-flute, corner-radius cutter with an extended neck delivers durable performance and smooth, high-precision finishes in demanding materials.

• Diameter: 4 mm
• Corner Radius: R1
• Overall Length: 20 mm
• Neck Type: Extended neck for access to deep pockets and complex geometries
• Flutes: 4-flute design enhances chip evacuation and surface finish
• Coating: Pulsar DMX coating enables optimized dry cutting and reduced wear
• Material: Solid carbide for rigidity and long tool life
• Recommended Machining: High-speed machining of pre-hardened steels up to HRc55

This end mill is ideal for applications where precision matters in confined spaces—think intricate pockets, undercuts, and tight radii. The corner radius reinforces the cutting edge, helping to minimize chipping and deliver consistent radii and smoother surfaces. The extended neck design reaches deep features without sacrificing rigidity, while the Pulsar DMX coating lowers friction during dry cutting, enabling higher feed rates and cooler operation. Built for reliability in demanding environments, it’s a strong choice for production runs involving pre-hardened steels and high-speed workflows.
