Hertel 750555 Square End Mill 5/16 in 4 Flute Carbide Ticn

Product Description

The HERTEL 750555 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 5/16-inch diameter, a 1/2-inch length of cut, and four flutes with a 30-degree right-hand helix for efficient chip evacuation and smooth surface finishes. The micrograin carbide substrate provides hardness and wear resistance, and the TiCN coating adds surface hardness to extend tool life in abrasive or high-heat cutting environments. At 2 inches overall length with a stub-length classification, it offers rigidity in setups where deflection is a concern. This tool is center-cutting, allowing plunge entry as well as peripheral and slot milling operations. Machinists and tool-and-die professionals are the primary users.

This end mill is suited for slot milling, profiling, and light pocketing operations on CNC machining centers and manual knee mills. The stub-length design reduces overhang and vibration, making it well-suited for rigid setups in production environments. The 5/16-inch shank diameter matches the cutter diameter, allowing use in standard collet chucks, end mill holders, or shrink-fit tooling of the same bore size. It is applicable in job shops and manufacturing facilities working with steel, stainless steel, cast iron, aluminum, and similar materials where a TiCN-coated carbide tool is appropriate.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• TiCN coating extends tool life in abrasive and elevated-temperature cutting conditions
• 4-flute spiral geometry with 30-degree right-hand helix for efficient chip evacuation
• Center-cutting design allows direct plunge entry without a pre-drilled pilot hole
• Stub-length classification minimizes deflection and improves rigidity in tight setups
• Mill diameter tolerance of plus 0.000 / minus 0.002 inches for consistent dimensional accuracy

Compatibility

Designed as a standard square end mill for use in CNC machining centers and manual milling machines equipped with toolholders accepting a 5/16-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Secure the shank in a properly sized collet or end mill holder to the manufacturer-recommended clamping torque for that holder type. Inspect the cutting edges and coating for chips or wear before each use, and verify runout with a dial indicator when dimensional tolerance is critical.
