Hertel E5249007 Ball End Mill 0.1094 in 2 Flute Carbide

Product Description

The HERTEL E5249007 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. It features a 0.1094-inch (7/64 inch) cutting diameter and a 0.375-inch length of cut, making it well suited for small-radius profiling, contouring, and slot milling in tight geometries. The two-flute, right-hand cutting configuration with a 30-degree helix angle supports efficient chip evacuation and smooth cutting action. At 1.5 inches overall length with a 0.125-inch shank diameter, this tool mounts directly in standard collet chucks and end mill holders. It ships uncoated and is intended for use by machinists and tool-and-die professionals working on CNC mills or manual milling machines.

This end mill is appropriate for light to medium-duty milling of ferrous and non-ferrous materials in both job shop and production environments. Its small diameter makes it a common choice for fine detail work, die cavities, and 3D contouring passes where larger tooling cannot reach. The single-end design means the tool is replaced rather than flipped when worn, keeping setup time low. This is a per-unit tool sold individually.

Key Features

• 0.1094-inch (7/64 inch) ball nose cutting diameter for small-radius profiling
• Solid carbide construction for rigidity and wear resistance
• 2-flute, right-hand cut and right-hand flute geometry
• 30-degree helix angle promotes efficient chip evacuation
• 0.375-inch length of cut with 1.5-inch overall length
• Uncoated finish; single-end configuration

Compatibility

Designed as a standard single-end ball nose end mill with a 0.125-inch straight shank, compatible with collet chucks and end mill holders accepting 1/8-inch shank tooling on CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists following standard tool-change procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the collet or holder to the recommended grip length and torque the retention hardware according to the tool holder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
