Description
The OSG Carbide 4 Flute End Mill Square is a long-length, center-cutting milling tool designed for general machining tasks. With a 10 mm diameter and four flutes, it delivers efficient material removal and reliable performance across a wide range of applications, including milling, slotting, and profiling in deep or hard-to-reach areas.
Designed for extended reach and versatility, this end mill lets you access recessed features and deep pockets without sacrificing cutting stability or efficiency. The carbide construction provides strong wear resistance and consistent performance through repeated use, making it a dependable choice for everyday milling work.
- Extended reach for deep pockets: Long length design allows access to hard-to-reach areas while maintaining rigidity and cutting efficiency, reducing the need for multiple tools or setups.
- Four-flute geometry for efficient material removal: Four flutes increase chip evacuation and support higher feed rates, enabling faster cycles and smoother finishes in general machining tasks.
- Center-cutting square end for versatile milling: Square-profile end with center-cutting capability enables plunging and contouring in a single operation, ideal for milling, slotting, and profiling.
This end mill helps streamline workflows by reducing tool changes and delivering repeatable, reliable results across a wide range of projects. The combination of extended reach, productive cutting geometry, and center-cutting capability supports faster setups, cleaner cuts, and improved overall productivity in both shop floors and job sites.
