Hertel E1051034 Square End Mill 17/32 in 4 Flute Hss

Product Description

The HERTEL E1051034 is a double-end square end mill manufactured from M7 high speed steel. It carries a 17/32 inch (0.5313 inch) cutting diameter with a 1-3/8 inch length of cut and a 5/8 inch shank diameter, giving an overall length of 5 inches. The tool runs a 4-flute, spiral flute geometry at a 30-degree helix angle with right-hand cut and right-hand flute orientation. It arrives uncoated and is suited for general-purpose milling operations on ferrous and non-ferrous workpiece materials. Licensed machinists, tool-and-die makers, and CNC setup technicians are the primary installers of this tooling.

This end mill is configured for use in vertical machining centers, knee mills, and manual milling machines where a regular-length, double-end tool is appropriate. The double-end design extends tool life by providing two usable cutting ends before the tool is retired. The 30-degree helix promotes efficient chip evacuation in slotting, profiling, and peripheral milling applications. The M7 HSS grade offers good toughness for interrupted cuts and general shop work where carbide is not required.

Key Features

• Double-end design provides two cutting ends for extended tool service life
• M7 high speed steel construction offers toughness for interrupted cuts
• 4-flute spiral geometry with 30-degree helix for efficient chip evacuation
• Right-hand cut and right-hand flute orientation for standard spindle use
• Uncoated finish suitable for re-sharpening and reconditioning
• Regular length classification for rigid setups and general milling work

Compatibility

Designed as an OEM-style replacement or direct-use tool for milling machines and machining centers accepting a 5/8 inch straight shank end mill holder, collet chuck, or Weldon-style holder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the shank fully in a collet or end mill holder and torque the retention hardware per the toolholder manufacturer specification before spindle engagement. Confirm spindle rotation direction matches the right-hand cut geometry before initiating a cut. Inspect the cutting edges for chips or wear at regular intervals and do not exceed the rated depth-of-cut envelope for the workpiece material.
