Description

2-flute carbide design: Efficient cutting with stable core and smooth chip clearance for small-diameter work.
2 mm cutting diameter: Ideal for tight radii, precise slots, and fine detail work.
20 mm reach (overall length): Enhanced access to deep cavities and recessed features.
Corner radius R0.3: Precisely defined corners for smoother transitions and accurate edge geometry.
Tapered neck design: Reduces vibration and chatter to improve surface finish and dimensional stability.
Solid carbide construction: Durable, wear-resistant material built for long life and consistent performance.

This end mill excels at delivering clean, accurate cuts in challenging materials and intricate geometries. The tapered neck minimizes tool deflection during long reach passes, while the corner radius reinforcement helps resist chipping at sharp corners. Use it for precision groove finishing, contouring sloped surfaces, and creating reliable radii on internal corners, all while maintaining tight tolerances and a smooth surface finish.
