Description
The OSG Variable Lead Optimal Flute Shape Endmill with a corner radius and a Weldon shank is designed to improve chip evacuation during milling operations.
Its variable lead and optimized flute geometry promote smooth chip flow, reducing the risk of chip jams and boosting overall efficiency.
- Variable Lead for Smooth Chip Evacuation: The alternating lead geometry reduces burr buildup and helps chips clear quickly, cutting downtime and improving surface quality on continuous milling operations.
- Corner Radius (R0.25) on 8 mm Diameter: The precise corner radius strengthens cutting edges and minimizes edge chipping, while the 8 mm diameter suits pocketing and contouring tasks for cleaner, more consistent finishes.
- Weldon Shank for Secure Toolholding: The Weldon shank provides reliable, repeatable grip in standard holders, minimizing runout and ensuring consistent performance across jobs.
This endmill helps you streamline workflows by maintaining steady chip flow, reducing downtime, and delivering consistent finishes across materials. The combination of variable lead, precise corner radius, and a robust Weldon shank translates to reliable production milling performance, enabling faster completion of tasks with fewer reworks.
