Hertel 750264 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The HERTEL 750264 is a solid carbide square end mill designed for precision milling operations in ferrous and nonferrous materials. It features a 5/8-inch cutting diameter, a 3/4-inch length of cut, and a 3-inch overall length, classifying it as a stub-length tool. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The AlTiN coating provides thermal resistance and extended tool life in high-temperature cutting environments. Micrograin carbide construction supports tight tolerances and consistent edge integrity across production runs. Licensed machinists and CNC operators working in job shops or production environments are the primary users of this tool.

This end mill is suited for slot milling, profiling, and peripheral milling in vertical and horizontal machining centers. The centercutting geometry allows for plunge entry directly into the workpiece without a pre-drilled hole. The stub-length format improves rigidity, reduces deflection, and is well-matched to applications where reach is limited and depth-of-cut control is critical. The 5/8-inch shank diameter is compatible with standard ER collets and end mill holders commonly found in CNC milling setups.

Key Features

• Solid micrograin carbide construction for dimensional stability and edge retention
• AlTiN coating for thermal resistance and extended tool life in ferrous applications
• Four right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Stub length (3/4-inch LOC, 3-inch OAL) maximizes rigidity and minimizes deflection
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard CNC machining centers and manual mills equipped with 5/8-inch collet chucks or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the holder and torque the retention hardware to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut.
