Description

2‑Flute Stub Cut Length: Short, rigid geometry optimized for precise milling with reduced deflection and reliable chip evacuation in shallow to mid-depth pockets.
Diameter: 4 mm
Overall Length: 20 mm
Corner Radius: R0.2 for controlled fillets and smoother corner finishes
Carbide Construction: Hard-wearing material that maintains sharpness and extends tool life when cutting hard materials
Corner Radius & Length Options: Available in a range of corner radii and effective lengths to fit diverse machining scenarios
Designed for High-Hardness Materials: Optimized cutting geometry to efficiently machine hardened steels and other tough workpieces

The end mill delivers tangible benefits in precision machining: longer tool life, cleaner corners, and steadier performance under high cutting forces. The combination of a compact stub length and a purpose-built corner radius helps reduce chatter, improve surface finish, and enable reliable finishing passes on hard materials. Whether you’re pocketing, profiling, or finishing intricate features, this Widin end mill is built to deliver consistent results and repeatable accuracy across jobs.
