Hertel E1030911 Square End Mill 1-1/4 in 2 Flute Hss

Product Description

The HERTEL E1030911 is a square end mill designed for general-purpose milling operations in ferrous and non-ferrous metals. Manufactured from M7 high speed steel, this tool features a 1-1/4 inch cutting diameter with a 1-5/8 inch length of cut and a 1 inch shank diameter for rigid toolholder engagement. The 30-degree helix spiral flute geometry promotes smooth chip evacuation and reduces cutting forces. With 2 flutes and a centercutting design, this end mill handles slotting, profiling, and plunge cutting. It is uncoated and runs in a right-hand cut, right-hand flute configuration. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual knee mills.

This end mill fits standard applications in job shops, maintenance machining, and production environments where a regular-length, large-diameter HSS tool is required. The 1 inch shank diameter suits common end mill holders and collet chucks sized for that bore. The 4-1/8 inch overall length keeps the tool compact enough for stable setups while providing sufficient reach for most workpiece features. It is well suited to slotting and peripheral milling in mild steel, aluminum, and similar materials at moderate cutting speeds.

Key Features

• 1-1/4 inch cutting diameter with 1-5/8 inch length of cut for substantial material removal
• M7 high speed steel construction provides toughness and resistance to chipping
• 30-degree helix spiral flute promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry into workpiece
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• Uncoated finish suitable for use with cutting fluids on a wide range of materials

Compatibility

Designed as an OEM-style replacement or standard tooling option for end mill holders and collet chucks with a 1 inch bore, used in conventional and CNC milling machines accepting regular-length square end mills.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the shank in a properly sized end mill holder or collet chuck, torquing the retention hardware to the toolholder manufacturer specification. Verify tool runout with a dial indicator before beginning the cut, and confirm cutting fluid supply is directed at the flutes during operation.
