Description
The OSG Carbide 4 Flute Variable Lead End Mill is a high-performance cutting tool designed for titanium and a broad range of general materials. With a 12 mm diameter and an R0.25 corner radius, this regular-length end mill delivers precise profiles and clean finishes, even in demanding workpieces. The TiAlN coating boosts wear resistance, helping you get more life out of each tool and maintain consistent results across jobs.
- Variable lead geometry: Reduces vibration and chatter for smoother cuts, stable tool engagement, and improved surface finish on titanium and other tough materials.
- TiAlN coating for extended tool life: Enhances wear and heat resistance, helping the cutter stay sharp longer in high-temperature cuts and demanding applications.
- 12 mm diameter with R0.25 corner radius (regular length): Delivers precise external profiles and reliable corner definition, enabling repeatable geometry and efficient setup in both titanium and general materials.
Designed for reliability and consistent performance, this end mill supports faster cycle times, fewer reworks, and smoother finishes across a range of projects—from precision titanium components to everyday metalworking tasks. Its robust carbide core, together with the TiAlN coating and optimized geometry, helps you achieve predictable results with confidence, every time you set up a cut.
