Hertel 750503 Square End Mill 7/16 Inch 2 Flute Solid Carbide

Product Description

The HERTEL 750503 is a solid carbide square end mill designed for precision milling operations in metal-cutting applications. With a 7/16 inch (0.4375 inch) mill diameter, a 1 inch length of cut, and a 30-degree helix angle, this tool delivers efficient chip evacuation and stable cutting performance in a wide range of ferrous and non-ferrous materials. The AlTiN coating improves heat resistance and extends tool life in high-temperature cutting environments. The 2-flute geometry and centercutting capability allow plunge entry as well as conventional peripheral and slot milling. This end mill is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is suited for milling slots, profiles, pockets, and contours in metalworking operations on CNC machining centers and manual mills. The right-hand cutting direction and micrograin carbide substrate make it a practical choice for general-purpose work in steel, stainless, and aluminum. The 7/16 inch shank diameter fits standard collets and end mill holders, and the 2-3/4 inch overall length provides reach without excessive overhang for most standard setups.

Key Features

• 7/16 inch (0.4375 inch) mill diameter with matching 7/16 inch shank for direct collet fit
• 1 inch length of cut supports slotting and profiling in typical stock removal applications
• AlTiN finish increases heat resistance and extends tool life in dry or semi-dry cutting
• 30-degree helix angle promotes smooth chip flow and reduces cutting forces
• Centercutting design allows plunge milling without a pre-drilled entry hole
• Micrograin solid carbide substrate provides hardness and edge retention

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 7/16 inch collets and end mill holders used on CNC machining centers and manual vertical mills.

Installation Notes

Installation is performed by a machinist or CNC setup technician. The machine spindle must be at a full stop and the tool changer or spindle lock engaged before mounting or removing the end mill. Ensure the collet and holder are clean and free of chips before seating the shank. Confirm runout with a dial indicator before beginning a production run to avoid premature edge wear or chatter.
