Hertel 750379 Square End Mill 5/16 in 4 Flute Solid Carbide

Product Description

The HERTEL 750379 is a solid carbide square end mill designed for precision milling operations across a range of ferrous and non-ferrous materials. It measures 5/16 inches in diameter with a 13/16-inch length of cut and a 2-1/2-inch overall length. The 4-flute, spiral design with a 30-degree helix angle promotes efficient chip evacuation and surface finish quality. A TiCN (titanium carbonitride) coating improves wear resistance and extends tool life in harder materials. Micrograin carbide construction provides the rigidity and edge retention expected in production and toolroom environments. This is a center-cutting tool capable of plunge and peripheral milling.

This end mill suits vertical milling machines, CNC machining centers, and manual knee mills in job shop, production, and maintenance applications. The 5/16-inch shank matches standard collets and end mill holders. Right-hand cut and right-hand flute geometry make it compatible with conventional spindle rotation. The regular-length configuration is well suited to shoulder milling, slotting, profiling, and contouring where a compact tool-to-holder stack is preferred over extended-reach versions.

Key Features

• 5/16-inch diameter with matching 5/16-inch shank for direct collet mounting
• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating for improved wear resistance in harder workpiece materials
• 4-flute spiral design with 30-degree helix angle for efficient chip flow
• Center-cutting geometry allows direct plunge entry into workpiece
• Right-hand cut, right-hand flute — compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 5/16-inch collets and end mill holders on vertical milling machines and CNC machining centers.

Installation Notes

Installation and tool changes must be performed with the machine powered off and spindle fully stopped. Use a calibrated torque wrench and the collet manufacturer's recommended procedure when seating and tightening the collet nut — do not overtighten. Inspect the shank and collet bore for chips or contamination before mounting. Follow applicable shop safety standards and machine tool manufacturer guidelines for tool overhang and maximum depth-of-cut parameters.
