Hertel 750788 Square End Mill 5/64 in 2 Flute Solid Carbide

Product Description

The HERTEL 750788 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 5/64 inch (0.0781 inch) cutting diameter and a 3/16 inch length of cut, this end mill handles slotting, profiling, and peripheral milling in tight spaces. The 2-flute geometry paired with a 30-degree spiral helix promotes efficient chip evacuation at high feed rates. A titanium nitride (TiN) coating increases surface hardness and reduces friction, extending tool life in production environments. Licensed machinists and CNC operators are the primary users of this tool.

This end mill is suited for light-duty milling operations on machining centers, CNC mills, and manual knee mills. Its 1/8 inch shank diameter fits standard ER collets and small-diameter toolholders common in precision shops. The centercutting design allows plunge entry, making it effective for pocket milling without a pre-drilled entry point. At 1-1/2 inch overall length, the tool maintains rigidity while accessing shallow-to-moderate depth features.

Key Features

• 5/64 inch (0.0781 inch) cutting diameter for small-feature milling
• Solid carbide construction for rigidity and wear resistance
• TiN coating reduces friction and extends tool life
• 2-flute spiral design with 30-degree helix for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut with single-end configuration

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 1/8 inch collet and toolholder systems used in CNC and manual milling applications.

Installation Notes

Installation is performed by machinists using appropriate ER collets or end mill holders rated for the 1/8 inch shank diameter. Confirm runout is within acceptable tolerance before cutting to avoid premature tool wear or breakage. Ensure the spindle and toolholder are clean and free of debris before seating the shank. Follow shop-standard speeds and feeds for solid carbide tooling at this diameter, as small-diameter carbide tools are sensitive to lateral deflection and improper feed rates.
