Description

The OSG Variable Lead Optimal Flute Shape Endmill with a corner radius and a Weldon shank is engineered to improve chip evacuation during machining operations. With a 10 mm cutting diameter and a corner radius of R1.5, this tool balances aggressive material removal with smooth finishes. The Weldon shank provides secure clamping and repeatable alignment, making it a dependable choice for a wide range of materials and applications.

Designed for machinists across experience levels, the variable lead and optimized flute geometry promote smooth chip flow, reduce chip jams, and improve overall machining efficiency. Whether you're pocketing, profiling, or finishing, this endmill delivers reliable performance and consistent results.

  • Variable Lead for Smooth Chip Flow: Guides chips away from the cut, reducing packing and downtime and helping maintain steady feeds for faster cycle times.
  • Optimal Flute Shape with Corner Radius R1.5: Flute geometry and the corner radius provide a balanced cutting action, cleaner finishes on corners and pockets, and longer edge life across a range of materials.
  • Weldon Shank for Secure Mounting: Rigid, repeatable alignment in collets and holders reduces runout and simplifies tool changes for consistent, reliable results.

This endmill delivers dependable performance across a wide range of applications, improving workflow, reducing interruptions, and helping you achieve repeatable, high-quality finishes. Its combination of efficient chip evacuation, reinforced corner geometry, and secure mounting makes it a practical choice for production runs, prototyping, and demanding machining tasks alike.
