Hertel E1032921 Square End Mill 1-1/4 in 6 Flute Hss

Product Description

The HERTEL E1032921 is a 6-flute square end mill designed for material removal and finishing cuts in ferrous and non-ferrous metals. Manufactured from M7 high speed steel with no coating applied, it measures 1.25 inches in diameter with a 2-inch length of cut and a 0.875-inch shank diameter. The 30-degree spiral flute geometry promotes chip evacuation and reduces heat buildup during extended cuts. At 4.5 inches overall length and 0.86 pounds, it fits standard vertical milling machines and machining centers used in job shop and production environments. Licensed machinists and tool-and-die professionals are the primary users.

This end mill is suited for peripheral milling, slotting, and profiling operations on steel, cast iron, and similar materials. The right-hand cut with right-hand flute orientation is the standard configuration for conventional and climb milling on manual mills and CNC machining centers. The non-center-cutting geometry means it is not designed for plunge cuts and should be entered into the workpiece from the side or through a pre-drilled hole. It fits applications where a large-diameter, multi-flute tool is needed for a smooth finish at lower feed rates.

Key Features

• 1.25-inch mill diameter with 2-inch length of cut for substantial axial engagement
• 6 flutes for improved surface finish and higher feed capability compared to 4-flute tools
• M7 high speed steel construction for toughness and resistance to chipping
• 30-degree helix angle spiral flute for efficient chip flow
• Right-hand cut, right-hand flute — standard orientation for most milling setups
• Uncoated — suitable for re-sharpening and use with cutting fluids

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines and machining centers accepting a 0.875-inch shank diameter end mill holder or collet chuck.

Installation Notes

Installation requires a properly sized end mill holder, collet chuck, or Weldon-style holder rated for 0.875-inch shanks. Ensure the spindle is fully powered down and locked before seating or removing the tool. Apply appropriate cutting fluid for the workpiece material to extend tool life. This tool is not center-cutting — do not use for direct plunge entry into solid material.
