Hertel E5250013 Ball End Mill 0.2031 in 4 Flute Solid Carbide

Product Description

The HERTEL E5250013 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.2031-inch (13/64-inch) cutting diameter and a 0.625-inch length of cut, this tool delivers controlled material removal in tight-tolerance applications. The four-flute configuration paired with a 30-degree right-hand helix angle promotes efficient chip evacuation and smooth surface finishes. The uncoated solid carbide construction provides rigidity and wear resistance in a compact, single-end geometry. Machinists and tool-and-die professionals use this end mill for contouring, profiling, and finishing passes where a ball nose radius is required.

This ball end mill is suited for use in CNC machining centers and manual milling machines where small-diameter, high-precision work is required. The 0.25-inch shank diameter and 2.5-inch overall length make it compatible with standard collet and end mill holder setups. Typical applications include mold and die work, part contouring, slot milling in aluminum, steel, and similar materials, and finish profiling on complex three-dimensional surfaces.

Key Features

• 0.2031-inch (13/64-inch) ball nose cutting diameter for tight-radius contouring
• Solid carbide construction for rigidity and long tool life
• Four flutes with 30-degree right-hand helix for efficient chip evacuation
• Uncoated finish suitable for a broad range of work materials without coating incompatibility concerns
• Single-end design with 0.25-inch shank for standard collet holder compatibility
• 2.5-inch overall length with 0.625-inch length of cut for reach in moderate-depth features

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for CNC and manual milling setups requiring a 0.25-inch shank collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling professional. Ensure the spindle is fully powered down and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully and evenly in the collet or tool holder and torque the retention mechanism to the machine or holder specification. Inspect the cutting edges for chips or damage before each use, as solid carbide tools are brittle and should not be used in setups with excessive runout or instability.
