Description

The OSG Carbide 2 Flute End Mill with Ball Nose is a versatile, general‑purpose cutting tool designed for contouring, profiling, and 3D machining. Built around a 12 mm diameter carbide body with a ball nose tip, it delivers smooth radii and precise finishes on complex shapes.

Ideal for engineers, machinists, and hobbyists alike, this end mill combines reliability with broad applicability across industries such as aerospace, automotive, and general manufacturing. The regular length and center-cutting capability provide confident plunging and consistent depth cuts for a wide range of workpieces.

  • Ball Nose Geometry for Smooth Contours: The rounded tip creates precise radii and smooth surface finishes on complex 3D profiles, reducing finishing passes and improving part quality.
  • Two Flute Design for Efficient Material Removal: A lightweight, rigid flute arrangement enables steady cuts, fast chip evacuation, and improved surface finish during profiling and contouring tasks.
  • Regular Length Centre Cutting for Versatility: Balanced tool length with center-cut capability allows plunging and versatile operation across many workpiece thicknesses.

This end mill helps you streamline production by delivering consistent, accurate results from the first pass. The carbide construction offers excellent wear resistance and long tool life, while the ball nose geometry and two-flute design help you achieve smooth surfaces with fewer passes. Its reliability and versatile capability make it a dependable choice for demanding general machining tasks, improving workflow and reducing downtime across your shop floor.
