Hertel 750640 Square End Mill 0.125 in 2 Flute Solid Carbide

Product Description

The HERTEL 750640 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.125 inch (1/8 inch) cutting diameter and a 0.25 inch length of cut, this end mill delivers sharp, accurate profiles in ferrous and non-ferrous materials. The titanium nitride (TiN) finish increases surface hardness and extends tool life by reducing friction and heat buildup at the cutting edge. A 30-degree spiral flute helix promotes efficient chip evacuation and smooth cutting action. This tool is handled by machinists and CNC operators in job shop, production, and toolroom environments.

This end mill suits close-tolerance slotting, profiling, and peripheral milling operations on vertical mills and CNC machining centers. Its 0.125 inch shank diameter fits standard ER collets and small-bore tool holders used in precision work on aluminum, brass, steel, and similar materials. The 1.5 inch overall length provides enough reach for typical shallow-pocket and slot applications without sacrificing rigidity. Single-end construction keeps the tool compact for tight setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiN coating reduces tool wear and improves chip flow at the cutting edge
• 30-degree helix spiral flute promotes efficient chip evacuation and reduces heat buildup
• Centercutting design allows plunge entry directly into the workpiece
• Right-hand cut configuration compatible with standard CNC and manual spindle rotation
• 2-flute geometry suited for slotting and profiling in softer metals and general-purpose milling

Compatibility

Designed as a general-purpose solid carbide square end mill compatible with standard 1/8 inch ER collets and small-bore end mill holders on vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the spindle before seating or removing the tool from the collet or tool holder. Ensure the collet bore and shank are clean and free of chips before tightening to the holder manufacturer's specified torque. Inspect the cutting edges for chipping or wear before each use, as solid carbide is brittle and susceptible to damage from improper handling or interrupted cuts.
