Hertel E1031921 Square End Mill 15/32 in 4 Flute Hss

Product Description

The HERTEL E1031921 is a 4-flute square end mill designed for general-purpose milling operations in metal fabrication and machining environments. It measures 15/32 inch (0.4688 inches) in cutting diameter with a 1 inch length of cut and a 3/8 inch shank diameter. Overall length is 2-11/16 inches. Constructed from M7 grade high speed steel, this end mill features a 30-degree right-hand spiral flute configuration suited for slotting, peripheral milling, and shoulder milling in a variety of workpiece materials. It is installed and operated by machinists and tool-and-die professionals on manual and CNC milling machines.

This end mill is appropriate for use in job shops, production machining cells, and maintenance environments where consistent stock removal is required. The regular-length geometry makes it well suited for standard-reach applications in ferrous and non-ferrous materials. With a right-hand cut and right-hand flute direction, it operates in conventional and climb milling setups. The uncoated HSS construction makes it a cost-effective choice for general steel, aluminum, and soft alloy operations where regrinding is an acceptable part of the tooling program.

Key Features

• 15/32 inch (0.4688 inches) cutting diameter with 1 inch length of cut
• M7 high speed steel construction for toughness and regrindability
• 4-flute, 30-degree helix spiral flute for efficient chip evacuation
• Right-hand cut and right-hand flute direction for standard milling setups
• Regular length geometry for standard-reach slotting and peripheral milling
• Uncoated finish suitable for general-purpose ferrous and non-ferrous machining

Compatibility

Designed as a general-purpose square end mill for use in standard milling machine spindles and CNC machining centers accepting a 3/8 inch straight shank.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully in a collet or end mill holder rated for the shank diameter before operation. Confirm spindle speed and feed rate are appropriate for the workpiece material and cutting diameter before engaging the cut. Inspect the cutting edges for wear or chipping before each use and replace or regrind as needed to maintain dimensional accuracy.
