Description
Meet the OSG Variable Lead Optimal Flute Shape Endmill with a Weldon shank—a precision cutting tool designed to keep chips moving and your workpiece intact. With a 20 mm diameter and a 4 mm corner radius, this endmill supports reliable radii and consistent results across a wide range of materials, while the Weldon shank delivers a secure, repeatable fit in standard toolholders.
- Variable Lead Geometry: Smooths chip formation and reduces intermittent engagement, helping chips evacuate more steadily and maintain stable cutting conditions.
- Optimized Flute Shape for Evacuation: Flutes are designed to clear chips quickly, lowering heat buildup and minimizing the risk of chip jams that can stall your workflow.
- Weldon Shank with R4 Corner Radius: Provides rigid, dependable tool seating and a precise corner radius for consistent finishes, even under demanding milling operations.
This endmill is a practical choice for machinists seeking dependable, high-performance results with efficient chip management. Its thoughtful geometry and robust shank design work together to improve throughput, reduce downtime, and deliver smooth, repeatable finishes across diverse machining tasks.
