Description
The OSG Carbide 4 Flute End Mill Square is a center-cutting, regular-length end mill with a 1 mm diameter.
Its four flutes and TiAlN coating make it well suited to general milling, slotting, and profiling across a range of materials, delivering reliable, precise results.
- Four-flute design for efficient material removal: The extra cutting edges enable faster chip removal and smoother finishes, helping you maintain productivity and consistent results across milling, slotting, and profiling tasks.
- TiAlN coating for longer tool life and wear resistance: The coating boosts heat resistance and reduces wear, extending tool life in demanding materials and reducing downtime from tool changes.
- Center-cutting geometry for versatile operations: This square-end, center-cutting design allows plunge cuts and flexible use in both vertical and horizontal milling, improving workflow and job flexibility.
Designed for reliability in everyday shop, production, and hobbyist environments, this end mill balances precision with durability. The carbide construction paired with TiAlN coating supports consistent cuts, clean finishes, and longer intervals between tool changes, helping you complete precision work with confidence and efficiency.
