Description

The OSG Carbide Centre Cutting End Mill is a square-edge, center-cutting tool designed specifically for aluminum workpieces. Its long-length geometry provides deep reach into challenging features while preserving efficient material removal and stable cutting performance. The 12 mm diameter makes it a versatile choice for a wide range of aluminum applications, from pockets to contours.

With a 12 mm diameter, this end mill is a reliable choice for machinists and hobbyists working on aluminum parts, delivering consistent performance across a variety of tasks—from profiling to complex contouring.

  • Center-Cutting Design: Enables plunging into aluminum and slotting without retracting the tool, boosting versatility and reducing cycle times.
  • Square-Edge Geometry: Delivers clean, flat-bottom cuts and consistent edge quality in aluminum, minimizing the need for extensive secondary finishing.
  • Long-Length, Stable Reach: Provides access to deep cavities and complex features while maintaining rigidity and reducing deflection for reliable, repeatable results.

This tool helps you streamline manufacturing workflows by enabling deeper access, reducing tool changes, and delivering stable, repeatable finishes on aluminum parts. The carbide construction offers wear resistance for dependable performance across projects, while the center-cutting capability and square-edge geometry support precise, high-quality components and parts. Choose this end mill to improve productivity, finish quality, and confidence in your aluminum milling work.
