Hertel E1031909 Square End Mill 0.75 in 4 Flute Hss

Product Description

The HERTEL E1031909 is a 4-flute square end mill manufactured from M7 high speed steel. It is designed for milling operations including slotting, profiling, and peripheral cutting on a wide range of ferrous and non-ferrous materials. The cutter features a 0.75 inch mill diameter, a 1.625 inch length of cut, and a 5/8 inch shank diameter with an overall length of 3.75 inches. The 30-degree right-hand spiral flute geometry promotes chip evacuation and provides smooth cutting action. Machinists and tool-and-die professionals install this tool in manual mills and CNC machining centers where standard uncoated HSS tooling is specified.

This end mill suits general-purpose material removal in job shop, maintenance, and production environments. The uncoated M7 HSS construction performs well in lower-speed applications and is well-suited to re-sharpening. The single-end configuration and right-hand cut and flute direction make it a standard choice for conventional milling setups. It is appropriate for use on mild steels, aluminum alloys, plastics, and similar workpiece materials in both manual and CNC applications.

Key Features

• 0.75 inch mill diameter with 1.625 inch length of cut for solid material engagement
• 4 spiral flutes at a 30-degree helix angle for efficient chip removal
• M7 high speed steel construction — resharpenable and suited to lower-speed cutting
• Right-hand cut and right-hand flute direction for conventional milling
• Uncoated finish — compatible with standard cutting fluids and lubricants
• Single-end design with 5/8 inch straight shank for secure collet or chuck retention

Compatibility

Designed as a standard-shank square end mill fitting any milling machine spindle or CNC machining center that accepts a 5/8 inch straight shank via collet, end mill holder, or milling chuck.

Installation Notes

This tool is installed by machinists in milling machine spindles using an appropriate 5/8 inch collet, end mill holder, or set-screw style holder. Ensure the machine spindle is fully powered down and locked out before tool changes. Verify shank seating depth and holder clamping torque per the holder manufacturer specifications before cutting. Do not exceed the recommended cutting parameters for M7 HSS tooling in the material being machined.
