Description
The OSG Variable Lead Optimal Flute Shape Endmill with a corner radius and a Weldon shank is a high-performance milling tool designed to improve chip evacuation and cutting efficiency across a wide range of materials. With a 16 mm diameter and a 3 mm corner radius (R3), this endmill is well-suited for pockets, contours, and finishing passes where precise geometry and reliable chip control matter.
Its unique combination of variable lead and an optimized flute profile promotes smooth chip flow, minimizes chip jams, and reduces heat buildup during operation. The Weldon shank delivers secure seating in standard toolholders for repeatable performance across jobs.
- Variable Lead Geometry: Encourages steady chip flow and reduces rubbing at the cutting edge, helping to prevent clogging and improve material removal rates.
- Corner Radius with Optimized Flutes: The corner radius strengthens cutting edges and improves finish on inside corners, while the flute geometry balances chip evacuation and cutting efficiency.
- Weldon Shank for Secure Fit: Provides rigid clamping, minimizes runout, and enables quick, repeatable tool changes across compatible machines.
This endmill helps you streamline your milling workflow by delivering reliable, consistent results with fewer interruptions. Efficient chip evacuation reduces downtime, while the robust Weldon shank and durable construction support longer tool life and repeatable performance across roughing and finishing tasks. Designed for engineers, machinists, and shops seeking predictable tool life and high-quality surfaces, it enables you to complete jobs faster with confidence.
