Hertel E1050022 Square End Mill 11/32 in 2 Flute Hss

Product Description

The HERTEL E1050022 is a double-end, square-profile end mill designed for milling operations on ferrous and non-ferrous metals in machine shop and production environments. Manufactured from M7 high speed steel with an uncoated finish, it features a 30-degree spiral flute geometry that promotes chip evacuation and reduces heat buildup during cutting. The 11/32-inch (0.3438-inch) cutting diameter pairs with a 9/16-inch length of cut, making it well suited to slotting, profiling, and peripheral milling at moderate depths. Installation and use is performed by machinists operating manual or CNC milling machines.

This end mill is a general-purpose tool intended for light-to-moderate material removal in job shop, toolroom, and production machining settings. Its double-end configuration provides two usable cutting ends, extending service life before replacement is required. The centercutting design allows plunge entry into workpiece material without a pre-drilled pilot hole. Right-hand cut and right-hand flute orientation are standard for conventional milling machine spindle rotation. The 3/8-inch shank diameter fits standard R8, ER, and similar collet systems commonly found on knee mills and CNC machining centers.

Key Features

• Double-end design provides two cutting ends per tool, reducing per-operation tooling cost
• M7 high speed steel construction offers good toughness and wear resistance for general milling applications
• 30-degree helix angle spiral flute promotes smooth cutting action and efficient chip removal
• Centercutting geometry allows direct plunge milling without a pilot hole
• Uncoated finish maintains sharp edge geometry and is suitable for re-sharpening
• Right-hand cut, right-hand flute — compatible with standard milling spindle rotation

Compatibility

Designed as an OEM-style replacement or standard toolroom end mill for use in any milling machine or machining center accepting a 3/8-inch shank diameter via R8, ER, or equivalent collet-style toolholding systems.

Installation Notes

Installation is performed by a qualified machinist. Power down and lock out the milling machine spindle before inserting or removing the end mill from the collet or toolholder. Confirm collet bore matches the 3/8-inch shank diameter and torque the drawbar or collet nut according to the machine manufacturer's specifications. Inspect the cutting edges for chipping or wear before each use and replace or resharpen as needed to maintain cut quality and dimensional accuracy.
