Hertel 750677 Square End Mill 13/64 in 2 Flute Carbide Tin

Product Description

The HERTEL 750677 is a single-end square end mill designed for precision milling operations in metalworking and machining applications. It features a solid carbide micrograin construction with a Titanium Nitride (TiN) coating, delivering extended tool life and resistance to wear at elevated cutting temperatures. The 13/64 inch (0.2031 inch) cutting diameter pairs with a 5/8 inch length of cut and a 30-degree helix angle for efficient chip evacuation. Two right-hand spiral flutes provide a balance of cutting edge strength and chip clearance. This tool is centercutting, allowing it to plunge directly into the workpiece. It is installed and operated by machinists, toolroom technicians, and CNC operators in production and job-shop environments.

This end mill is suited for milling slots, pockets, profiles, and contours in ferrous and non-ferrous metals. The TiN coating improves surface hardness and reduces friction during cuts in materials such as alloy steels, cast iron, and hardened materials. The 1/4 inch shank diameter fits standard collets and tool holders commonly found on vertical machining centers, CNC mills, and manual knee mills. It is appropriate for light to moderate material removal in tight-tolerance work requiring a small-diameter tool.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• Titanium Nitride (TiN) coating extends tool life and reduces heat buildup
• Centercutting design allows direct plunge entry into the workpiece
• 30-degree right-hand helix promotes smooth chip flow and stable cutting action
• Two flutes provide adequate chip clearance for small-diameter milling
• Single-end configuration with a standard 1/4 inch shank for broad toolholder compatibility

Compatibility

Designed as a standard single-end square end mill for use in collet chucks and end mill holders accepting a 1/4 inch shank diameter on CNC and manual milling machines.

Installation Notes

A licensed machinist or CNC operator should install this tool in a properly rated collet or end mill holder torqued to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cut. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Follow applicable shop safety procedures and machine guarding requirements during setup and operation.
