Hertel 750025 Square End Mill 3/8in 2-flute Solid Carbide

Product Description

The HERTEL 750025 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineered materials. It features a 3/8 inch cutting diameter, a 5/8 inch length of cut, and a 2-inch overall length with a 3/8 inch shank diameter. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Built from micrograin solid carbide, this tool delivers consistent edge integrity across demanding applications. It ships in a bright, uncoated finish and is configured as a single-end tool. Installation and use require standard collet or end mill holder setups appropriate for the 3/8 inch shank.

This end mill is suited for slotting, profiling, and peripheral milling operations in job shop, production, and maintenance-repair environments. Its 2-flute configuration provides maximum chip clearance, making it well suited for softer metals, aluminum, and applications requiring aggressive material removal. The right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling machines. The centercutting geometry allows plunge entry as well as ramp and contour paths without a pre-drilled pilot hole.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• 2-flute design maximizes chip clearance for high material removal rates
• 30-degree helix angle promotes smooth cutting and efficient chip evacuation
• Centercutting geometry enables direct plunge, ramp, and contour entry
• Right-hand cut and right-hand spiral for standard CNC and manual mill compatibility
• Bright uncoated finish suitable for a wide range of general-purpose applications

Compatibility

Designed as a general-purpose square end mill compatible with standard 3/8 inch collets and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with end mill holder selection and runout tolerances. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Use a proper collet or end mill holder rated for the 3/8 inch shank diameter and verify adequate tool stick-out for the intended cut depth. Follow machine manufacturer guidelines and applicable shop safety standards when setting speeds and feeds.
