Description
The OSG Variable Lead Optimal Flute Shape Endmill with a square-edge design and a Weldon shank is a high-performance cutting tool engineered to keep chips moving smoothly during milling. Featuring variable lead geometry and an optimized flute profile, it promotes uninterrupted chip evacuation, reducing the risk of clogging and heat buildup for more efficient machining. Sized at 16 mm, this endmill is built for reliable performance across a wide range of materials and applications.
- Variable lead for smooth chip flow: Staggered flute spacing along the tool length enhances continuous chip evacuation, lowers cutting resistance, and helps maintain steady cutting action for improved cycle times.
- Optimized flute geometry with square edge: The carefully tuned flute shape combined with a square edge delivers crisp engagement, strong cutting action, and consistent finishes with reduced burr formation across various materials.
- Weldon shank for secure, repeatable mounting: Provides rigid clamping and minimal runout in standard toolholders, enabling quick changes, reliable retention, and repeatable results session after session.
This endmill is designed to help you maximize uptime and deliver dependable results. The combination of efficient chip management, robust cutting geometry, and a secure Weldon shank supports smoother workflows, fewer interruptions, and consistent performance from roughing through finishing tasks.
