Hertel 750753 Square End Mill 5/16 in 2 Flute Solid Carbide

Product Description

The HERTEL 750753 is a solid carbide square end mill designed for precision milling operations across a wide range of metalworking applications. With a 5/16-inch mill diameter and a 1-5/8-inch length of cut, this tool delivers sharp, consistent performance in slotting, profiling, and peripheral milling. The 30-degree spiral helix and right-hand cutting direction promote efficient chip evacuation and reduce cutting forces. A titanium nitride (TiN) finish increases surface hardness and extends tool life. This end mill is installed and operated by machinists and CNC programmers working in job shops, production environments, and toolroom settings.

This end mill suits general-purpose milling in ferrous and non-ferrous materials where a compact diameter and moderate length of cut are required. The 5/16-inch shank diameter matches the mill diameter, making it compatible with standard collet chucks and end mill holders of that bore size. The centercutting design allows plunge milling directly into a workpiece without a pre-drilled entry point, expanding its usefulness in both roughing and finishing operations. Its 4-inch overall length provides sufficient reach for most standard setups without sacrificing rigidity.

Key Features

• Solid carbide construction for hardness, wear resistance, and dimensional stability
• TiN coating increases surface hardness and reduces friction at the cutting edge
• 30-degree helix angle promotes smooth chip flow and reduced heat buildup
• Centercutting geometry enables direct plunge entry into the workpiece
• Two-flute configuration provides larger chip gullets for improved chip clearance
• Right-hand spiral flute design for use in standard CNC and manual milling setups

Compatibility

Designed for use in standard collet chucks, shrink-fit holders, or end mill holders with a 5/16-inch bore. Suitable for CNC machining centers and manual knee mills configured for that shank size.

Installation Notes

This tool should be installed by a qualified machinist or CNC operator following safe toolholding practices. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Secure the shank to the full recommended engagement depth in the toolholder to prevent pullout under cutting loads. Verify runout with a dial indicator before beginning production cuts, as excessive runout accelerates edge wear and reduces surface finish quality.
