Hertel E699924539 Ball End Mill 0.75in 4 Flute Carbide Tin

Product Description

The HERTEL E699924539 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. With a 0.75 inch mill diameter and a 1 inch length of cut, this single-end tool delivers controlled material removal in profiling, contouring, and finishing applications. The four-flute geometry provides a balance of 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 tool is intended for use by machinists and toolroom professionals working on CNC machining centers and manual mills.

This ball end mill suits general-purpose milling tasks including 3D contouring, cavity work, and radius profiling in materials such as steel, aluminum, and cast iron. The 0.75 inch shank diameter matches the mill diameter for straightforward toolholder fitment in standard collet and end mill holders. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC spindle configurations. It ships as a single-end tool, so the working end is fixed at one side of the 3 inch overall length body.

Key Features

• 0.75 inch ball nose diameter for radius profiling and 3D contouring
• 4 flutes for improved surface finish and cutting efficiency
• Solid carbide construction for rigidity and wear resistance
• TiN coating reduces friction and extends cutting edge life
• Right-hand cut and right-hand helix for standard CNC spindle use
• Single-end design with 3 inch overall length

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for standard 3/4 inch collet and end mill holder tooling systems on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the tool from the holder. Seat the shank to the recommended engagement depth in the collet or holder and torque the clamping mechanism per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish.
