Hertel 750719 Square End Mill 7/64 in 2 Flute Solid Carbide

Product Description

The HERTEL 750719 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard-material applications. It features a 7/64 inch (0.1094 inch) cutting diameter with a 3/8 inch length of cut and a 1/8 inch shank diameter, making it well suited for tight-clearance slotting, profiling, and contouring work. The 30-degree spiral helix and two-flute geometry promote efficient chip evacuation at smaller diameters. A titanium nitride (TiN) coating adds surface hardness and reduces friction at the cutting edge. Overall length is 1-1/2 inches. This tool is installed and operated by machinists, tool-and-die makers, and CNC technicians.

This end mill is appropriate for use in vertical machining centers, CNC mills, and manual knee mills where small-diameter, high-precision cuts are required. The centercutting design allows direct plunge entry into the workpiece without a pre-drilled pilot hole, supporting both slot milling and ramping operations. The right-hand cutting direction conforms to standard spindle rotation on conventional machine tools. It is commonly used in job shops, toolrooms, and production environments handling ferrous and non-ferrous materials.

Key Features

• Solid carbide construction provides rigidity and wear resistance at small diameters
• TiN coating reduces cutting friction and extends tool life on ferrous materials
• 30-degree helix spiral flute promotes smooth chip flow in shallow-to-moderate depth cuts
• Centercutting geometry enables direct plunge milling without a pilot hole
• Two-flute design balances chip clearance and edge strength at 7/64 inch diameter
• Right-hand cut matches standard machine spindle rotation

Compatibility

Designed as a standard 1/8 inch shank square end mill suitable for use in collet chucks, end mill holders, and drill chucks sized for 1/8 inch shank tooling on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the collet or holder and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges for chips or wear before each use, as carbide tools are brittle and can fracture if run in a damaged state.
