Hertel 750039 Square End Mill 7/32 in 4 Flute Carbide

Product Description

The HERTEL 750039 is a solid carbide square end mill designed for precision milling in metal, composites, and other hard materials. It features a 7/32 inch (0.2188 inch) cutting diameter, a 1/2 inch length of cut, and a 1/4 inch shank diameter, with a 2 inch overall length. The 4-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and stable cutting at higher feed rates. The centercutting geometry allows for direct plunge entry as well as conventional side milling. This end mill is used by machinists and tooling professionals in job shops, production environments, and maintenance machining applications.

This end mill is suited for slotting, profiling, and contouring operations on ferrous and non-ferrous materials. Its uncoated solid carbide construction makes it a practical choice for general-purpose work where a coated tool is not required. The 1/4 inch shank fits standard collet chucks and end mill holders common on CNC machining centers and manual knee mills alike. The right-hand cut and right-hand flute configuration is the standard orientation for most milling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• 4-flute spiral design with 30-degree helix angle for smooth chip flow
• Centercutting capable — supports plunge milling as well as peripheral cuts
• Right-hand cut, right-hand flute — standard orientation for most CNC and manual mills
• Uncoated finish suitable for general-purpose milling applications
• 1/4 inch shank fits widely available collet and end mill holder tooling

Compatibility

Designed as a general-purpose replacement or stock end mill for any milling machine or machining center accepting a 1/4 inch shank, including standard ER collet systems and end mill holders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Ensure the collet or holder bore is clean and the shank is fully seated to the correct insertion depth before tightening. Verify runout with a dial indicator after installation to confirm proper seating. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
