Hertel E699924514 Ball End Mill 0.0781 in 4 Flute Carbide

Product Description

The HERTEL E699924514 is a solid carbide ball end mill designed for high-precision milling in demanding machining environments. With a 0.0781 inch (5/64 inch) diameter and a 4-flute configuration, this tool is built for finishing passes and contour milling where accuracy at small scales is critical. The TiN (titanium nitride) coating increases surface hardness and reduces tool wear during extended cuts. A 0.1875 inch (3/16 inch) length of cut and 1.5 inch overall length make it suitable for shallow-depth detail work in ferrous and non-ferrous materials. Machinists and tooling technicians working on CNC mills and manual machines select this end mill for fine-feature profiling and slot work.

This end mill is used in precision machining shops, tool and die operations, and production environments requiring small-diameter ball nose profiling. The single-end design with a 0.125 inch shank diameter fits standard collet chucks and end mill holders. Right-hand cutting and right-hand flute direction suit conventional CNC milling setups. It is appropriate for use in both roughing preparation steps and finish contour passes on molds, dies, and complex part geometries at the smaller end of the diameter range.

Key Features

• 0.0781 inch (5/64 inch) ball nose diameter for fine-detail milling
• 4-flute geometry supports improved surface finish and chip evacuation
• TiN coating extends tool life and reduces friction during cutting
• Solid carbide construction provides rigidity and wear resistance
• Right-hand cut and right-hand helix for standard CNC spindle compatibility
• Single-end design with 0.125 inch shank for use in standard collet systems

Compatibility

Designed for use in CNC and manual milling machines equipped with standard collet chucks or end mill holders accepting a 0.125 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth before tightening. Inspect the tool edge under magnification before use and discard any end mill showing chipping or coating damage.
