Hertel 750616 Square End Mill 1/8 in 2 Flute Carbide Tin

Product Description

The HERTEL 750616 is a 2-flute solid carbide square end mill designed for precision milling in metalworking and machining operations. It features a 1/8 inch cutting diameter with a 1 inch length of cut, a 1/8 inch shank diameter, and a 3 inch overall length. The 30-degree spiral helix and TiN (titanium nitride) finish support efficient chip evacuation and extended tool life in ferrous and non-ferrous materials. Right-hand cut geometry and centercutting capability allow this tool to plunge, slot, and profile in a single setup, making it well suited for close-tolerance work on CNC machining centers and manual mills.

This end mill is intended for small-diameter milling applications where tight geometry and tool rigidity are critical. Common applications include slotting, profiling, and pocketing in steel, aluminum, and similar materials. The solid carbide substrate provides the stiffness needed at this diameter to minimize deflection and maintain dimensional accuracy in production and toolroom environments. Licensed machinists, CNC operators, and tool-and-die professionals are the primary users of this tool.

Key Features

• 1/8 inch cutting diameter with 1 inch length of cut for small-feature machining
• Solid carbide construction for rigidity and wear resistance at small diameters
• TiN coating reduces friction and improves tool life in a range of workpiece materials
• 30-degree spiral helix promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Right-hand cut, single-end configuration compatible with standard ER and collet toolholding systems

Compatibility

Designed as an OEM-style replacement or standard toolroom end mill for 1/8 inch collet or ER collet toolholding systems on CNC machining centers and manual vertical mills requiring a 2-flute solid carbide square end mill.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the toolholder. Use a properly sized collet or end mill holder rated for a 1/8 inch shank to prevent slippage under cutting loads. Inspect the cutting edges and coating for wear or chipping before each use, as tool condition directly affects part quality and surface finish at this diameter.
