Hertel E8053044 Square End Mill 11/16 in 4 Flute Hss Tin

Product Description

The HERTEL E8053044 is a double-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Manufactured from M7 high speed steel with a titanium nitride (TiN) finish, it delivers solid wear resistance and edge retention across a broad range of machining applications. The tool features a 30-degree helix angle with spiral flutes and a centercutting geometry, allowing it to plunge directly into a workpiece. With an 11/16-inch cutting diameter and 1-5/8-inch length of cut, it handles slot milling, profile milling, and facing on manual mills and CNC machining centers alike. Total weight is 0.51 pounds.

This end mill is suited for job shops, tool rooms, and production environments running conventional or CNC vertical milling machines. The double-end configuration extends tool life by providing two usable cutting ends before the tool is retired. Right-hand cut and right-hand flute geometry align with standard spindle rotation. Typical applications include steel, alloy steel, cast iron, and aluminum workpieces where a general-purpose HSS tool is appropriate over carbide. The 3/4-inch shank diameter fits standard ER, Weldon, and collet-style toolholders in that bore size.

Key Features

• Double-end design provides two cutting ends for extended tool life
• M7 high speed steel construction with TiN coating for improved wear resistance
• Centercutting geometry allows direct plunge entry into workpiece
• 30-degree helix spiral flutes promote efficient chip evacuation
• Right-hand cut and right-hand flute for standard spindle compatibility
• 4-flute configuration balances chip load and surface finish

Compatibility

Designed as an OEM-style replacement or direct-use end mill for vertical milling machines and machining centers accepting a 3/4-inch shank diameter toolholder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool from the holder. Seat the shank to the full recommended insertion depth in the toolholder and torque set screws per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
