Hertel 750244 Square End Mill 7/16 in 4 Flute Solid Carbide

Product Description

The HERTEL 750244 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 7/16 inch (0.4375 inch) cutting diameter, a 1 inch length of cut, and a 30-degree helix angle with spiral flutes. The AlTiN finish extends tool life in high-heat cutting environments. This is a centercutting tool, allowing plunge and ramp entry. It installs as a single-end tool with a 7/16 inch shank and an overall length of 2-3/4 inches. Machinists and CNC operators in production and tool room environments are the primary users.

This end mill is suited for slotting, profiling, and peripheral milling applications in machine shops, maintenance environments, and manufacturing facilities. The regular length classification and 1 inch length of cut make it appropriate for standard-depth passes in ferrous alloys, aluminum, and similar workpiece materials. The right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling setups. Micrograin carbide construction supports elevated feed and speed parameters compared to standard-grade carbide tooling.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for extended tool life in high-temperature cutting applications
• 30-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows plunge milling and ramp entry
• Right-hand cut and right-hand flute orientation for standard spindle use
• 4-flute configuration balances chip clearance and surface finish

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 7/16 inch collets, end mill holders, and shrink-fit holders accepting a 7/16 inch shank diameter on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator using an appropriate end mill holder or collet rated for the 7/16 inch shank diameter. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Verify runout with a dial indicator after seating the tool to confirm concentricity before cutting. Follow machine manufacturer guidelines and shop safety procedures for tool clamping torque.
