Hertel E8050056 Square End Mill 7/8 in 2 Flute Hss Tin

Product Description

The HERTEL E8050056 is a square end mill designed for general-purpose milling in a wide range of metalworking and machining applications. The cutter measures 7/8 inches in diameter with a matching 7/8-inch shank diameter and delivers a 1-9/16-inch length of cut (1.5625 inches). The tool is constructed from M7 high speed steel and features a titanium nitride (TiN) coating to extend tool life and improve wear resistance. A 30-degree helix angle promotes efficient chip evacuation, and the centercutting geometry allows for direct plunge entry into workpiece material. At 5-1/2 inches overall length, this mill suits a range of standard milling setups.

This end mill is suited for use in vertical mills, knee mills, and CNC machining centers performing slotting, profiling, and peripheral milling operations on steel, cast iron, aluminum, and other machinable metals. The two-flute configuration provides generous flute volume for chip clearance, making it a reliable choice in slotting passes and applications where chip packing is a concern. It is typically installed and operated by machinists and tool-and-die professionals in production and job-shop environments.

Key Features

• 7/8-inch mill diameter and matching shank diameter for direct collet or end mill holder mounting
• M7 high speed steel construction offers toughness and re-grindability
• TiN coating increases surface hardness and reduces friction at the cutting edge
• 30-degree right-hand spiral helix promotes chip flow and reduces cutting forces
• Centercutting design enables plunge milling without a pre-drilled entry hole
• Two-flute geometry maximizes chip clearance in slotting and full-width cuts

Compatibility

Designed as a standard 7/8-inch shank end mill compatible with collet chucks, end mill holders, and milling machine spindles accepting 7/8-inch round shank tooling in ANSI-standard configurations.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder rated for the 7/8-inch shank diameter. The machine spindle should be fully stopped and the drawbar or retention mechanism secured before mounting or removing the tool. Verify runout with a dial indicator after seating to confirm proper tool engagement. Follow the machine manufacturer and tooling manufacturer guidelines for speed and feed parameters based on workpiece material.
