Hertel 750223 Square End Mill 3/4 Inch 4 Flute Solid Carbide

Product Description

The HERTEL 750223 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 3/4 inch cutting diameter and a 2-1/4 inch length of cut, it handles slotting, profiling, and peripheral milling in a wide range of ferrous and non-ferrous materials. The 4-flute configuration with a 30-degree spiral helix provides a balance of chip evacuation and surface finish quality. A titanium nitride (TiN) coating extends tool life by reducing friction and wear at the cutting edge. This tool is installed and operated by machinists and CNC programmers working in job shop, production, and tool-and-die settings.

This end mill suits vertical and horizontal milling machines as well as CNC machining centers requiring a standard 3/4 inch shank. The 5 inch overall length accommodates setups where moderate reach is needed without sacrificing rigidity. The centercutting geometry allows plunge entry directly into the workpiece, enabling ramping and helical interpolation toolpaths in addition to standard side milling. Right-hand cut orientation is compatible with conventional spindle rotation on the vast majority of machining equipment in use today.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiN finish reduces cutting friction and extends tool service life
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Centercutting design supports plunge entry, ramping, and helical interpolation
• 4-flute spiral geometry balances material removal rate with surface finish quality
• Right-hand cut, compatible with standard spindle rotation

Compatibility

Designed as a standard 3/4 inch shank square end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems that accept a 3/4 inch straight shank on vertical mills, horizontal mills, and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or unloading the tool. Verify shank engagement depth meets the tool holder manufacturer minimum grip length recommendation. Do not exceed the machine spindle speed or feed rate limits for the tool diameter and material being cut.
