Hertel 750415 Square End Mill 1/16 in 4 Flute Altin Carbide

Product Description

The HERTEL 750415 is a single-end square end mill engineered for precision milling in ferrous and non-ferrous materials. Built from micrograin solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, this tool delivers extended wear resistance and thermal stability at elevated cutting speeds. It carries a 1/16 inch mill diameter, a 1/8 inch length of cut, and a 30-degree right-hand helix with four flutes. The stub-length configuration provides rigidity in tight setups. This tool is installed and operated by machinists, tool-and-die makers, and CNC technicians working on mills and machining centers.

This end mill is suited for slot milling, profiling, and contouring operations in ferrous alloys, hardened steels, stainless steels, and high-temperature alloys where the AlTiN coating provides a thermal barrier that extends tool life. The stub length and small diameter make it effective in confined cavities and fine-detail work common in mold, die, and precision component machining. It is a single-end tool, so the full length is available for setup reach within the 1-1/2 inch overall length. Center-cutting capability allows plunge entry without a pre-drilled pilot hole.

Key Features

• AlTiN coating improves heat resistance and extends tool life in hard and abrasive materials
• Micrograin solid carbide substrate provides rigidity and edge retention at small diameters
• Four-flute spiral design with 30-degree right-hand helix balances chip evacuation and finish quality
• Center-cutting geometry allows direct plunge milling without a pre-drilled hole
• Stub length classification reduces deflection risk on small-diameter tools
• 1/8 inch shank diameter fits standard collets and end mill holders on most CNC and manual mills

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for machining centers and manual mills accepting a 1/8 inch shank diameter collet or end mill holder.

Installation Notes

This tool is installed by machinists and CNC operators using a compatible collet or end mill holder sized for a 1/8 inch shank. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Confirm runout with a dial indicator after seating to avoid premature edge failure at this diameter. Follow machine manufacturer feed and speed recommendations for the work material and coating type; do not exceed the rated depth of cut for the 1/8 inch length of cut.
