Hertel 750226 Square End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The HERTEL 750226 is a solid carbide square end mill designed for precision milling operations in metal and composite materials. With a 3/16 inch cutting diameter and 4-flute spiral geometry, this end mill delivers clean, accurate cuts in slots, pockets, and profiles. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A titanium nitride (TiN) finish increases surface hardness and extends tool life in ferrous and non-ferrous applications. This tool is intended for use by machining professionals in CNC and manual milling setups.

This end mill is suited for light to medium material removal on ferrous metals, aluminum, and similar workpiece materials. The centercutting design allows direct plunge entry without pre-drilling. With a 5/8 inch length of cut and 2 inch overall length, it fits compact toolholding setups and is well matched to benchtop CNC mills and vertical machining centers handling small-feature work.

Key Features

• Solid carbide construction for rigidity and wear resistance
• 4-flute spiral design for smooth surface finish and efficient chip removal
• 30-degree helix angle reduces cutting forces and improves chip flow
• TiN coating increases tool hardness and extends service life
• Centercutting geometry allows direct plunge milling
• Right-hand cut and right-hand flute configuration for standard spindle use

Compatibility

Designed as a standard shank end mill compatible with 3/16 inch collets, end mill holders, and toolholding chucks used in CNC and manual vertical milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing tooling. Seat the shank fully into the collet or holder and torque the retention hardware per the toolholder manufacturer specification. Verify runout with a dial indicator before engaging a cut, particularly on tight-tolerance work.
