Description

The OSG Carbide 4-Flute End Mill Square, Regular Length, Center-Cutting, 1.5 mm diameter, is a versatile carbide tool designed for general machining tasks. With its four-flute configuration, it delivers efficient material removal and precise corners for milling, slotting, and profiling across a wide range of materials.

This end mill is built for reliable everyday shop use. Its regular-length body provides solid rigidity for general applications, while the square cutting geometry supports accurate pockets and clean external contours—even during higher-feed passes or tougher materials.

  • Four-flute design for efficient material removal: Four cutting edges share the chip load, enabling faster material removal while maintaining a smooth edge and clean finishes for milling, slotting, and profiling.
  • Regular-length, center-cutting versatility: The balanced body length offers dependable rigidity for general tasks, and center-cutting capability allows plunging and pocket milling without changing tools.
  • Carbide construction for durability and consistency: Hardened carbide resists wear, maintains sharpness over repeated use, and delivers reliable, consistent performance across jobs and materials.

Designed to support a smooth, confident workflow, this end mill helps you achieve precise results with fewer reworks and tool changes. Its durable carbide construction and robust 4-flute geometry work together to deliver dependable performance from first pass to finish, making it a trusted choice for engineers, machinists, and hobbyists alike.
