Hertel 750513 Square End Mill 9/64 in 4 Flute Solid Carbide

Product Description

The HERTEL 750513 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 9/64 inch (0.1406 inch) cutting diameter, 4-flute spiral geometry, and a 30-degree helix angle, this end mill delivers efficient chip evacuation and a clean square shoulder cut. The titanium nitride (TiN) coating reduces friction and extends tool life in ferrous and non-ferrous materials. Right-hand cut and right-hand flute orientation follow standard CNC and manual milling conventions. Centercutting capability allows for direct plunge entry without pre-drilling.

This end mill is suited for slot milling, shoulder milling, and profiling passes in light-duty to medium-duty machining applications. The 3/16 inch shank diameter fits standard collets and end mill holders used in CNC machining centers, knee mills, and benchtop milling machines. The 1/2 inch length of cut and 2 inch overall length make it well suited for shallow-depth passes in tight workholding setups where tool overhang must be minimized. Machinists and toolroom technicians working with aluminum, mild steel, stainless steel, and similar materials are the primary users.

Key Features

• 9/64 inch (0.1406 inch) cutting diameter for fine-detail milling work
• 4-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• TiN finish reduces friction and extends tool life on ferrous and non-ferrous materials
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute for standard CNC and manual mill compatibility
• Solid carbide construction provides rigidity and wear resistance in precision applications

Compatibility

Designed as an OEM-style solid carbide end mill for use with standard 3/16 inch collets and end mill holders in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Secure the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Ensure the spindle and all machine axes are at a full stop before inserting or removing tooling. Verify runout with a dial indicator after installation, particularly given the small diameter, to avoid deflection-related tool breakage during operation.
