Hertel 750260 Square End Mill 9/16 in 4 Flute Solid Carbide

Product Description

The HERTEL 750260 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard materials. With a 9/16 inch cutting diameter, a 1-1/4 inch length of cut, and a 3-1/2 inch overall length, this tool is built for standard milling setups that demand tight tolerances and consistent chip evacuation. The four-flute spiral geometry at a 30-degree helix angle balances cutting efficiency with surface finish quality. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling machine applications. Solid carbide construction provides the rigidity and wear resistance required for productive metal removal rates.

This end mill is suited for use in machine shops, tool rooms, and production floor environments where ferrous and non-ferrous materials are machined on vertical mills, CNC machining centers, and knee mills. The centercutting design allows plunge cuts as well as peripheral and slot milling operations. The uncoated carbide substrate makes it a practical choice for aluminum, brass, and general-purpose steel cutting where a coated tool is not required. Machinists and CNC operators are the primary users of this tool class.

Key Features

• Solid carbide construction for high rigidity and extended tool life compared to HSS alternatives
• Four flutes with 30-degree spiral helix for efficient chip evacuation and smooth surface finish
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut, right-hand flute orientation compatible with standard spindle rotation
• Uncoated finish suitable for aluminum, brass, and general-purpose steel applications
• 9/16 inch shank diameter matches 9/16 inch cutting diameter for consistent tool holding

Compatibility

Designed for use in standard milling machine collets, end mill holders, and hydraulic or shrink-fit toolholders accepting a 9/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the holder to the minimum engagement depth recommended by the toolholder manufacturer before tightening. Verify runout with a dial indicator before beginning production cuts.
