Hertel E699924490 Ball End Mill 0.0313 in 4 Flute Carbide

Product Description

The HERTEL E699924490 is a single-end ball end mill designed for precision milling of contoured surfaces, slots, and pockets. Built from solid carbide, it delivers the rigidity and wear resistance required for high-speed cutting in ferrous and non-ferrous materials. The mill measures 0.0313 inches in diameter with a 0.0625-inch length of cut and is coated with Titanium Nitride (TiN) to extend tool life and reduce friction at the cutting edge. The 4-flute geometry provides a strong core and smooth surface finish in finish-milling applications. This tool is typically installed and operated by machinists and CNC programmers working on close-tolerance parts.

This end mill is suited for finish profiling, 3D contour milling, and die and mold work where a small-diameter ball-nose profile is required. The 0.0313-inch diameter makes it appropriate for fine-detail work on small features and intricate geometries. With a 1/8-inch shank diameter and 1.5-inch overall length, it is compatible with standard collet chuck systems on CNC machining centers and manual mills. Right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups.

Key Features

• Solid carbide construction for rigidity and long tool life in demanding materials
• Titanium Nitride (TiN) coating reduces friction and increases surface hardness at the cutting edge
• 4-flute design supports improved surface finish and core strength in finish-milling passes
• Ball-end geometry for 3D contouring, profiling, and blending radii
• Right-hand cut and right-hand helix for standard CNC milling spindle direction
• Single-end configuration for direct chuck mounting

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill compatible with standard 1/8-inch collet chucks and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully in the collet or tool holder and torque the collet nut to the holder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, especially given the small diameter of this tool.
