Hertel 750322 Square End Mill 1in 4 Flute Solid Carbide

Product Description

The HERTEL 750322 is a solid carbide square end mill designed for high-performance milling operations in ferrous and non-ferrous materials. With a 1-inch mill diameter, 3-inch length of cut, and 4 flutes ground from micrograin carbide, this tool delivers rigidity and wear resistance in demanding applications. A titanium nitride (TiN) coating reduces friction and extends tool life at the cutting edge. The 30-degree helix angle promotes efficient chip evacuation, and the right-hand cutting and flute direction are standard for conventional CNC and manual milling setups. Licensed machinists and tool-and-die professionals are the primary users of this end mill.

This end mill is suited for profiling, slotting, and peripheral milling in production and job-shop environments. The 1-inch shank diameter mates with standard ER, side-lock, and shrink-fit toolholders common on vertical machining centers and knee mills. The 6-inch overall length provides clearance for deeper setups without requiring extended-reach tooling. The centercutting geometry allows plunge entry where application requirements permit. This tool is packaged as a single unit.

Key Features

• Micrograin solid carbide substrate for superior hardness and edge retention
• TiN coating reduces built-up edge and extends tool life in steel and cast iron
• 4-flute, right-hand spiral geometry for efficient chip evacuation and surface finish
• 30-degree helix angle balances cutting force and chip flow in medium-to-hard materials
• Centercutting design permits plunge milling entry
• Single-end configuration for standard toolholder mounting

Compatibility

Designed as an OEM-style replacement or direct tooling option for 1-inch shank milling applications on vertical machining centers, CNC mills, and manual knee mills using standard ER collet, side-lock, or shrink-fit toolholders.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before mounting or removing the end mill. Confirm the toolholder is clean and the shank seats fully before tightening to the holder manufacturer's specified torque. Verify runout with a dial indicator before initiating a cut to protect both the tool and the workpiece.
