Hertel E1050011 Square End Mill 11/64 in 2 Flute Hss

Product Description

The HERTEL E1050011 is a double-end, square-profile end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Manufactured from M7 high speed steel with a bright, uncoated finish, it features a 0.1719-inch (11/64-inch) cutting diameter and a 7/16-inch length of cut. The two-flute, right-hand spiral design promotes efficient chip evacuation in slotting, profiling, and peripheral milling applications. With a 3/8-inch shank diameter and 3-1/8-inch overall length, this tool is well suited for use in standard milling machine and CNC machining center collets. The double-end configuration extends tool life by providing two usable cutting ends.

This end mill is intended for use in machine shops, tool rooms, and maintenance environments where tight-tolerance milling work is performed. The 30-degree helix angle delivers a balance of cutting efficiency and edge strength suitable for a broad range of milling tasks. The centercutting geometry allows plunge entry, giving the operator flexibility for pocket and slot operations. It is typically installed by machinists and CNC operators working with manual mills, knee mills, or vertical machining centers.

Key Features

• M7 high speed steel construction for toughness and wear resistance in general milling applications
• Double-end design provides two cutting ends, maximizing tool value and service life
• 30-degree helix angle balances chip flow with cutting edge stability
• Centercutting geometry enables direct plunge entry into workpiece material
• Right-hand cut and right-hand flute spiral for standard spindle rotation compatibility
• Bright, uncoated finish suitable for use with cutting fluids on a wide range of materials

Compatibility

Designed as an OEM-style replacement and standard tooling option for milling machines and CNC machining centers accepting a 3/8-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine power isolated. The shank should be cleaned and inspected before seating in the collet or end mill holder to ensure concentricity and prevent runout. Follow machine manufacturer torque specifications for the collet nut. Verify correct spindle rotation direction before engaging the cut, as this tool is ground for right-hand rotation only.
