Hertel 750414 Square End Mill 1/8 in 2 Flute Solid Carbide

Product Description

The HERTEL 750414 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.125 inch cutting diameter, a 0.500 inch length of cut, and a 1.500 inch overall length, this end mill is built for tight-tolerance work in small-diameter applications. The two-flute spiral configuration with a 30-degree helix angle promotes efficient chip evacuation. A titanium nitride (TiN) coating adds surface hardness and reduces friction at the cutting edge. This tool is installed and used by machinists and tool-and-die professionals in CNC and manual milling setups.

This end mill is suited for slotting, profiling, and contouring operations in ferrous and non-ferrous materials. The 0.125 inch shank diameter matches the cutting diameter, making it compatible with standard collet chucks and end mill holders sized for 1/8 inch tooling. The centercutting geometry allows plunge milling in addition to conventional peripheral cutting, adding versatility for cavity work and pocket milling. Right-hand cut direction is standard for conventional spindle rotation on most CNC machining centers and knee mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiN finish reduces cutting friction and extends tool life in general-purpose milling
• 2-flute spiral design promotes chip clearance in slotting and plunge operations
• 30-degree helix angle balances cutting force and surface finish
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut for compatibility with standard CNC and manual spindle rotation

Compatibility

Designed for use with standard 1/8 inch collet chucks and end mill holders on CNC machining centers, knee mills, and manual milling machines configured for right-hand rotation.

Installation Notes

Installation is performed by qualified machinists following shop safety protocols. The spindle must be fully stopped and locked before inserting or removing the tool from the collet or holder. Verify collet size matches the 0.125 inch shank diameter before tightening. Inspect the cutting edges and coating for chips or damage before each use, as solid carbide tooling can fracture under improper clamping or excessive runout.
