Hertel 750179 Square End Mill 7/16 in 4 Flute Carbide

Product Description

The HERTEL 750179 is a solid carbide square end mill designed for precision milling in metal, alloy, and hard material applications. With a 7/16 inch (0.4375 inch) mill diameter, a 1 inch length of cut, and a 4-flute spiral configuration, this tool delivers clean, accurate profiles in general-purpose and finish milling operations. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Micrograin carbide construction provides hardness and edge retention well beyond standard high-speed steel tooling. This end mill is centercutting, allowing plunge entry as well as standard peripheral and slot milling. It is sold individually and suited for use on CNC machining centers and manual mills.

This end mill is intended for trade machinists, toolroom technicians, and shop floor CNC operators working in job shop, production, and maintenance machining environments. The uncoated micrograin carbide substrate makes it a solid choice for dry cutting or applications where coating compatibility with the workpiece material is a consideration. The right-hand cut and right-hand flute geometry follow standard spindle rotation conventions on vertical and horizontal milling machines. Its regular-length profile fits standard tool holders for quick changeover in production settings.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows both plunge and peripheral milling operations
• Uncoated finish suitable for dry cutting and coating-sensitive applications
• Right-hand cut and right-hand flute for compatibility with standard CNC and manual mills
• Regular length profile fits conventional end mill holders without special tooling

Compatibility

Designed as a standard-shank replacement or spare for vertical and horizontal milling machines accepting a 7/16 inch shank end mill in a collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before loading or removing the end mill. Seat the shank fully in the collet or holder to the recommended engagement depth and torque the retention hardware per the tool holder manufacturer specifications. Inspect the cutting edges for chipping before each use and confirm runout with a dial indicator when surface finish or dimensional tolerance is critical.
