This tool excels at creating precise contour details and smooth transitions with reliable rigidity in shallow to deep pockets. The 2‑flute design facilitates efficient chip evacuation in softer metals, helping maintain a clean cut and steady finishes. The Weldon 16 mm shank provides secure seating in collets and holders, while the long reach and neck relief enable access to features deep within parts without sacrificing rigidity. With a 30° helix and a 12° rake, it delivers consistent cutting action, good surface finish, and predictable performance during copy milling tasks.
