Hertel E1030903 Square End Mill 11/16 in 2 Flute Hss

Product Description

The HERTEL E1030903 is a 2-flute square end mill manufactured from M7 high speed steel. It features an 11/16 inch (0.6875 inch) cutting diameter, a 1-5/16 inch length of cut, and a 1/2 inch shank diameter. The overall length is 3-5/16 inches. The uncoated spiral flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute orientation. Center-cutting capability allows this tool to plunge directly into workpiece material. It is suited for milling operations in job shops, maintenance environments, and production settings where HSS tooling is specified.

This end mill is intended for use in manual mills and CNC machining centers running ferrous and non-ferrous materials at moderate cutting speeds. The regular-length profile and 1/2 inch shank make it compatible with standard end mill holders, collet chucks, and Weldon-style tool holders. The 2-flute design provides good chip clearance in slotting applications and when cutting softer workpiece materials such as aluminum and mild steel. A licensed machinist or tooling technician typically selects and installs this tooling.

Key Features

• 11/16 inch cutting diameter with 1-5/16 inch length of cut for regular-depth milling
• M7 high speed steel construction provides toughness and edge retention without a coating
• 30-degree helix angle spiral flute promotes smooth cutting action and chip evacuation
• Center-cutting design allows direct plunge entry into solid material
• Right-hand cut and right-hand flute configuration matches standard spindle rotation
• 2-flute geometry maximizes chip clearance in slotting and full-width cuts

Compatibility

Designed as a standard replacement or production end mill for use with 1/2 inch end mill holders, collet chucks, and Weldon-style adapters in manual and CNC milling equipment.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Confirm the shank is inserted to the recommended minimum engagement depth for the holder type in use. Follow applicable machine tool safety standards and shop procedures when setting tool offsets and securing the holder.
