Hertel 750299 Square End Mill 0.5 in 2 Flute Solid Carbide Tin

Product Description

The HERTEL 750299 is a solid carbide square end mill designed for precision milling operations across a wide range of metalworking and machining applications. With a 0.5 inch cutting diameter, 1 inch length of cut, and 3 inch overall length, this single-end tool delivers consistent dimensional control in both roughing and finishing passes. The 2-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation, while the titanium nitride (TiN) coating improves surface hardness and wear resistance. Right-hand cut orientation is standard. Licensed machinists and tool-room technicians are the primary users of this tool.

This end mill is suited for milling slots, pockets, profiles, and peripheral cuts on CNC machining centers and manual mills. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, expanding its use in die-and-mold work, fixture fabrication, and general production machining. The 0.5 inch shank diameter mates with standard ER, Weldon, and shrink-fit toolholders commonly found in both vertical and horizontal machining setups. Its compact 3 inch OAL promotes rigidity and reduces deflection in confined workspaces.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• TiN coating extends tool life and reduces built-up edge at elevated cutting speeds
• 30-degree helix spiral flute improves chip flow and reduces cutting forces
• Centercutting geometry allows direct plunge milling without a pilot hole
• Right-hand cut, single-end configuration with consistent 0.5 inch cutting diameter
• 2-flute design provides clearance for chip evacuation in slotting and pocketing

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill suitable for standard 0.5 inch collet and Weldon-style toolholders used in CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, and confirm feed, speed, and depth-of-cut parameters are appropriate for the workpiece material before operation.
