Hertel E1031916 Square End Mill 1 in 4 Flute Hss 30 Helix

Product Description

The HERTEL E1031916 is a 4-flute square end mill designed for general-purpose milling operations in high speed steel (HSS) grade M7. It carries a 1 inch cutting diameter, a 1-7/8 inch length of cut, and a 4-1/8 inch overall length with a 7/8 inch shank diameter. The 30-degree right-hand helix promotes efficient chip evacuation during peripheral and slot milling cuts. The bright, uncoated finish is suited to applications where additional coating is not required or where regrinding is anticipated. This tool is installed and operated by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill fits standard vertical milling setups and is well suited to ferrous and non-ferrous workpiece materials commonly encountered in job shop, maintenance, and production environments. The regular-length configuration and 7/8 inch straight shank allow direct mounting in standard end mill holders, collet chucks, and Weldon-style holders without extended reach. The non-centercutting geometry means this tool is intended for peripheral and side milling rather than direct plunging. Typical applications include profiling, slotting, and shoulder milling on steel and aluminum stock.

Key Features

• 1 inch cutting diameter with 4 flutes for balanced material removal and surface finish
• Grade M7 high speed steel construction provides toughness and wear resistance in general milling applications
• 30-degree right-hand spiral helix promotes chip flow away from the cut zone
• 7/8 inch shank diameter fits standard end mill holders and collet systems
• Bright, uncoated finish allows economical regrinding when worn
• Regular length profile keeps tool deflection low in standard depth-of-cut applications

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for vertical mills and CNC machining centers accepting a 7/8 inch straight-shank end mill holder or collet.

Installation Notes

A licensed machinist or qualified machine operator should install this tool. Ensure the machine spindle is fully de-energized and at a complete stop before changing tooling. The shank must be clean and fully seated to the minimum engagement depth specified by the holder manufacturer before tightening. Do not use this non-centercutting end mill for direct axial plunge cuts, as it is not designed for that operation.
