Hertel E1080116 Square End Mill 1-1/4 in 2 Flute Hss

Product Description

The HERTEL E1080116 is a single-end, square-profile end mill designed for milling operations in ferrous and non-ferrous materials. Manufactured from M7 high speed steel with a bright, uncoated finish, it measures 1.25 inches in diameter with a 3-inch length of cut and a 5.5-inch overall length. The 30-degree helix angle and two-flute spiral geometry promote chip evacuation and reduce cutting forces in slotting, profiling, and peripheral milling applications. This tool is center-cutting, allowing direct plunge entry. It is intended for use by machinists and tool-and-die professionals working on manual mills or CNC machining centers.

This end mill suits general-purpose material removal in job shop and production environments. The 1.25-inch shank diameter matches standard R8, CAT, BT, and other common toolholder bores at that size. The 3-inch length of cut accommodates deep-pocket and stepped-surface work where shorter flute lengths fall short. The bright, uncoated finish is appropriate for aluminum, mild steel, and similar materials where coating is not required and re-sharpening ease is valued. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling on most vertical and horizontal machining platforms.

Key Features

• M7 high speed steel construction for toughness and re-sharpenability
• 1.25-inch mill diameter with matching 1.25-inch shank for rigid, straight-shank toolholder fitment
• 3-inch length of cut handles deep-pocket and stepped-surface applications
• 30-degree helix angle with two spiral flutes promotes efficient chip flow
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Bright, uncoated finish suited to aluminum, mild steel, and dry or flood-coolant cutting

Compatibility

Designed for use in straight-shank toolholders accepting a 1.25-inch shank diameter, compatible with R8 collet chucks, end mill holders, and similar tooling systems on vertical knee mills, bed mills, and CNC machining centers.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully powered down and at a complete stop. The shank should be inserted to the full recommended engagement depth in the toolholder and secured per the toolholder manufacturer's torque guidance. Verify runout with a dial indicator before cutting operations begin. Handle HSS end mills with care to avoid edge chipping during storage and setup.
