Hertel E5250006 Ball End Mill 0.0938 in 4 Flute Carbide

Product Description

The HERTEL E5250006 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. With a 0.0938-inch (3/32-inch) cutting diameter and a 0.375-inch length of cut, this tool is built for small-diameter profiling, contouring, and finish milling passes. The four-flute geometry improves chip evacuation and surface finish compared to two-flute designs. The 30-degree helix angle balances cutting efficiency with tool stability in ferrous and non-ferrous materials. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills where tight tolerances and fine surface finishes are required.

This ball end mill suits applications in mold and die work, aerospace component machining, and precision part manufacturing. The single-end, right-hand cutting configuration is standard for CNC vertical machining centers. The 1/8-inch shank diameter allows use in collet systems and small-bore tool holders. The uncoated carbide construction makes it a reliable choice for dry or light-coolant cutting in aluminum, brass, mild steel, and similar materials. It is well suited for shops requiring a dependable small-diameter ball end mill for detailed profiling and 3D contour work.

Key Features

• 0.0938-inch (3/32-inch) ball nose cutting diameter for small-feature milling
• Four flutes for improved surface finish and material removal rate
• 30-degree right-hand helix for balanced cutting action and chip flow
• Solid carbide construction for rigidity and wear resistance
• Uncoated finish suitable for a range of common workpiece materials
• Single-end design with 1/8-inch straight shank for standard collet compatibility

Compatibility

Designed as a standard single-end ball end mill with a 1/8-inch shank diameter, compatible with collet chucks and tool holders accepting 1/8-inch round shanks in CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists following standard tooling procedures. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the 1/8-inch shank fully in the collet or tool holder and torque the collet nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the cutting operation to avoid premature tool wear or breakage on this small-diameter end mill.
