Hertel E8032901 Square End Mill 1-1/4 in 6 Flute Hss Tin

Product Description

The HERTEL E8032901 is a 6-flute, single-end square end mill designed for material removal in milling operations on ferrous and non-ferrous metals. Built from M7 high speed steel with a TiN (titanium nitride) finish, it offers improved wear resistance and surface hardness over uncoated HSS tooling. The mill measures 1.25 inches in diameter with a 1-inch shank diameter and an overall length of 4.5 inches. A 30-degree helix angle and spiral flute geometry promote efficient chip evacuation during full-slot and peripheral milling cuts. This tool is installed and operated by machinists and tool-and-die professionals on manual and CNC milling equipment.

The E8032901 is suited for general-purpose milling applications in job shop and production environments. Its 2-inch length of cut accommodates moderate-depth passes in steel, alloy steel, and similar materials. The right-hand cut and right-hand flute configuration is standard for conventional vertical milling setups. The regular-length profile makes it a practical choice for face milling, shoulder milling, and contouring operations where extended reach is not required.

Key Features

• 6-flute spiral design improves surface finish and feed rate capability compared to lower-flute-count end mills
• M7 high speed steel substrate provides toughness and resistance to chipping in interrupted cuts
• TiN coating increases surface hardness and reduces friction at the cutting edge
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Right-hand cut and right-hand flute for standard milling machine compatibility
• Non-centercutting geometry — not intended for direct plunge entry

Compatibility

Designed as a standard-shank square end mill for use in milling machines and machining centers accepting a 1-inch diameter straight shank via collet, end mill holder, or Weldon-style toolholder.

Installation Notes

This end mill is installed by machinists using an appropriate end mill holder or collet rated for the 1-inch shank diameter. Ensure the machine spindle is fully stopped and the tool is securely clamped before beginning any cut. Because this tool is non-centercutting, avoid direct axial plunge cuts — use a ramping or helical entry path instead. Always verify spindle speed and feed rate against published HSS cutting data for the workpiece material before operation.
