Hertel E1031052 Square End Mill 13/16 in 4 Flute Hss

Product Description

The HERTEL E1031052 is a single-end, square-profile end mill designed for milling operations in ferrous and non-ferrous metals. It is manufactured from M7 high speed steel and is supplied uncoated. The cutter features a 13/16 inch (0.8125 inch) diameter, a 1-7/8 inch length of cut, and a 3/4 inch shank diameter, giving it a 4-1/8 inch overall length. Four spiral flutes at a 30-degree helix angle promote efficient chip evacuation and stable cutting action. Right-hand cut and right-hand flute geometry follows standard milling convention. This tool is intended for use by machinists and tool-and-die professionals operating manual knee mills or CNC machining centers.

The E1031052 is suited for peripheral milling, slotting, and profiling cuts in general-purpose shop environments. Its uncoated M7 HSS construction makes it a practical choice for conventional milling of mild steel, alloy steel, aluminum, and similar materials where carbide tooling is not required. The 30-degree helix provides a balance of cutting edge strength and shear action appropriate for a wide range of depth-of-cut and feed combinations. This end mill is not center-cutting, so it is not intended for direct plunge operations into solid material.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the holder. The shank should be fully seated in the toolholder to the recommended engagement depth per the holder manufacturer. Confirm runout with an indicator before commencing cuts, especially in tight-tolerance applications.
