Hertel 750383 Square End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The HERTEL 750383 is a solid carbide square end mill designed for high-performance milling in metal, alloy, and composite workpiece materials. Built with a 3/8-inch diameter and 4 spiral flutes, this end mill delivers clean, accurate cuts in a wide range of CNC and manual milling applications. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. A micrograin carbide construction provides the hardness and wear resistance needed for demanding production environments. Machinists and toolroom professionals rely on this geometry for slotting, profiling, and peripheral milling operations.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills where a 3/8-inch shank is required. The 1-1/2-inch length of cut and 6-inch overall length allow access to moderate-depth features without sacrificing rigidity. Right-hand cutting and right-hand flute direction are standard for conventional spindle rotation. The centercutting capability allows direct plunge entry into the workpiece, eliminating the need for a pre-drilled pilot hole in many applications. This tool ships individually and is appropriate for job shops, production floors, and maintenance machining.

Key Features

• Solid micrograin carbide construction for hardness and long tool life
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge milling
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Bright/uncoated finish suitable for a broad range of workpiece materials
• No chipbreaker, variable helix, or variable index for predictable, consistent performance

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 3/8-inch collets, chucks, and tool holders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully within a properly sized collet or end mill holder before operation, and verify runout with a dial indicator before cutting. Power down and lock out the machine spindle before changing or adjusting tooling. Consult the machine tool manufacturer guidelines for maximum spindle speed and feed rate recommendations appropriate to the workpiece material.
