Hertel E1035116 Square End Mill 1-1/4 in 6 Flute Hss

Product Description

The HERTEL E1035116 is a 6-flute square end mill designed for general-purpose milling operations in ferrous and non-ferrous metals. Ground from M7 high speed steel with a bright, uncoated finish, this tool delivers consistent chip evacuation and edge retention in production machining environments. The 1-1/4 inch diameter matches a 1-1/4 inch straight shank, making it compatible with standard ER and shell mill holders of that bore size. With a 4 inch length of cut and 6.5 inch overall length, this end mill handles deep-slot and peripheral milling passes where extended reach into the workpiece is required. It is a non-center-cutting tool with right-hand cut and right-hand flute direction.

This end mill is suited for horizontal and vertical milling machine applications including slotting, profiling, and face milling on steel, alloy steel, cast iron, and similar materials. The M7 HSS grade provides good toughness and wear resistance for interrupted cuts and moderate-speed operations. It is appropriate for job shops, tool rooms, and production floor environments where HSS tooling is preferred over carbide for interrupted or variable-load conditions. A machinist or CNC operator installs this tool in a standard end mill holder or collet chuck sized for a 1-1/4 inch shank.

Key Features

• 1-1/4 inch (1.2500 inch) diameter with matching 1-1/4 inch shank for direct holder fitment
• 6 flutes for improved surface finish and higher feed rates compared to fewer-flute designs
• 4 inch length of cut supports deep slotting and extended peripheral milling passes
• M7 high speed steel grade for toughness and resistance to shock loading
• Bright, uncoated finish — suitable for use with or without cutting fluid
• Right-hand cut, right-hand helix; non-center-cutting design

Compatibility

Designed as an OEM-style replacement or direct-fitment end mill for standard end mill holders, collet chucks, and milling arbors with a 1-1/4 inch bore. Confirm holder bore and projection length before installation.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Seat the shank fully into the holder and torque the retention fasteners per the holder manufacturer specifications. Verify runout with a dial indicator before engaging a cut, particularly given the extended overall length of 6.5 inches.
