Hertel 750230 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The HERTEL 750230 is a 4-flute solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide with an AlTiN (Aluminum Titanium Nitride) finish, it delivers hardness and heat resistance suited for cutting ferrous and non-ferrous materials at elevated speeds. The 30-degree spiral helix and centercutting geometry allow both peripheral and plunge cutting. With a 0.125-inch mill diameter and 0.500-inch length of cut, this tool targets small-feature work and slot milling in tight tolerances. Licensed machinists and CNC programmers working in job shops or production environments are the primary users.

This end mill is sized for light-duty to medium-duty milling passes on ferrous metals, hardened steels, aluminum alloys, and similar materials. The AlTiN coating extends tool life in dry or near-dry cutting conditions by reducing friction and oxidation at the cutting edge. The 1.500-inch overall length and 0.125-inch shank fit standard collets and end mill holders on CNC machining centers and manual knee mills. The regular-length configuration suits general-purpose slotting, profiling, and contouring where extended reach is not required.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN finish improves heat resistance and extends tool life in dry machining
• 4-flute configuration balances chip evacuation with surface finish quality
• 30-degree right-hand spiral helix provides smooth cutting action and reduced chatter
• Centercutting geometry enables direct plunge entry without a pre-drilled pilot hole
• Mill diameter tolerance of +0.000 / -0.002 inches ensures consistent fit and finish

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool compatible with standard 1/8-inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC technician familiar with speeds, feeds, and tool-holding practices. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the end mill from the collet. Verify collet runout and holder cleanliness before seating the shank to maintain diameter tolerance and prevent premature wear. Follow machine manufacturer guidelines and applicable shop safety standards when setting cutting parameters.
