Hertel 750448 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The HERTEL 750448 is a 4-flute solid carbide square end mill designed for precision milling in metal, composite, and hard material applications. The cutter measures 0.125 inches in diameter with a 0.75-inch length of cut and a 2.25-inch overall length. It features an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life at elevated cutting speeds. The micrograin carbide substrate provides edge retention and rigidity suited to high-feed operations. This tool is installed and operated by machinists and toolroom professionals in CNC and manual milling environments.

This end mill is well suited for slotting, profiling, and plunge-cutting operations in ferrous and non-ferrous workpieces. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. The spiral flute configuration and right-hand cut with right-hand flute pattern make it compatible with standard spindle rotation on conventional and CNC milling machines. It is classified as a long-length tool, giving additional reach for deeper-pocket applications.

Key Features

• 4-flute spiral geometry for improved surface finish and material removal rate
• AlTiN coating for elevated heat resistance and extended tool life in ferrous materials
• Centercutting design allows direct plunge milling without a starter hole
• Micrograin solid carbide substrate for rigidity and edge retention
• 30-degree helix angle promotes efficient chip evacuation
• Right-hand cut and right-hand flute for standard spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling machines accepting a 0.125-inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully in the collet or tool holder to the recommended grip depth before torquing the drawbar or collet nut. Verify spindle speed and feed rate against published cutting data for the workpiece material and coating type before engaging the cut. Inspect the cutting edges for chips or wear before each use and replace the tool if edge integrity is compromised.
