Hertel E699924500 Ball End Mill 0.0781 in 2 Flute Carbide

Product Description

The HERTEL E699924500 is a solid carbide ball end mill designed for precise milling operations in metal, composite, and hard-material applications. With a 0.0781-inch (5/64-inch) mill diameter and a 0.1875-inch (3/16-inch) length of cut, this tool handles small-diameter finishing and profiling work where accuracy is critical. The two-flute geometry supports chip evacuation in tight pockets and contoured surfaces. A titanium nitride (TiN) coating improves surface hardness and extends tool life in abrasive cutting conditions. This is a single-end tool with right-hand cutting and right-hand flute direction, suited for CNC machining centers and manual milling setups operated by skilled machinists and toolroom technicians.

This ball end mill is well suited for finishing passes on complex 3D contours, die and mold work, and detail profiling in ferrous and non-ferrous materials. Its small diameter makes it appropriate for intricate features such as narrow slots, fillets, and radius blending in precision part manufacturing. The 1/8-inch shank diameter is compatible with standard collets and end mill holders commonly found in vertical machining centers and CNC routers.

Key Features

• 0.0781-inch (5/64-inch) mill diameter for small-feature and detail milling
• 0.1875-inch (3/16-inch) length of cut for controlled depth engagement
• Solid carbide construction for rigidity and wear resistance
• TiN coating increases surface hardness and reduces tool wear in abrasive materials
• 2-flute design promotes efficient chip evacuation in confined pockets
• Right-hand cut and right-hand helix; single-end configuration

Compatibility

Designed for use with standard 1/8-inch collets and end mill holders on CNC machining centers, vertical mills, and compatible milling setups accepting right-hand single-end carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/8-inch shank fully into the collet or tool holder and torque the retaining nut per the holder manufacturer's specifications. Confirm runout with a dial indicator before beginning a production run, particularly given the small diameter of this tool.
