Hertel E699924414 Ball End Mill 0.1406 in 4 Flute Carbide

Product Description

The HERTEL E699924414 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. It features a 0.1406-inch (9/64-inch) cutting diameter and a 0.3125-inch (5/16-inch) length of cut, making it well suited for contouring, profiling, and slotting in tight geometries. The four-flute, right-hand cutting configuration delivers efficient chip evacuation and surface finish quality. A Titanium Nitride (TiN) coating increases surface hardness and reduces friction at the cutting edge, extending tool life in ferrous and non-ferrous materials. This is a double-end tool, providing two usable cutting ends from a single shank.

This end mill is used in CNC machining centers and manual mills for finish milling, die and mold work, and contour passes on steel, aluminum, and similar materials. The small diameter makes it appropriate for detail work, cavity milling, and fine-feature profiling. At 2 inches overall length with a 3/16-inch shank diameter, it fits standard collet chucks and end mill holders found in most shop environments. Machinists and tool-and-die professionals working in production or job-shop settings will find this tool suitable for high-precision applications where geometry control is critical.

Key Features

• 0.1406-inch (9/64-inch) ball nose diameter for fine contouring and profiling
• Four flutes with right-hand cutting and right-hand flute direction for improved finish and chip flow
• Solid carbide construction for rigidity and wear resistance
• TiN coating for reduced friction, increased hardness, and extended tool life
• Double-end design provides two cutting ends per tool
• 0.3125-inch length of cut suits shallow-to-moderate depth passes in confined areas

Compatibility

Designed for use in standard collet chucks, shrink-fit holders, and end mill holders accepting a 3/16-inch shank diameter. Suitable for CNC machining centers and manual milling machines running right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify collet size matches the 3/16-inch shank before tightening to the holder manufacturer's specified procedure. Confirm runout within acceptable limits before beginning a cutting pass to protect both the tool and the workpiece.
