Hertel E5014020 Ball End Mill 0.3125 in 2 Flute Carbide

Product Description

The HERTEL E5014020 is a single-end ball end mill ground from solid carbide and intended for precision milling operations in ferrous and non-ferrous materials. The tool measures 0.3125 inches in cutting diameter with a 1.125-inch length of cut and a 3-inch overall length. A 2-flute geometry with a 30-degree right-hand helix provides efficient chip evacuation in slotting, profiling, and contouring passes. The uncoated carbide substrate makes this mill a straightforward choice for applications where coating compatibility or re-sharpening is a consideration. Right-hand cutting direction suits standard CNC and manual milling setups.

This end mill is suited for general-purpose machining centers, CNC knee mills, and manual milling machines used in toolroom, production, and prototype environments. The 5/16-inch shank diameter fits standard ER collets and end mill holders commonly found in vertical machining centers and CNC routers. The 1.125-inch length of cut is practical for shallow-to-moderate depth profiling and 3D contouring where rigidity and minimal deflection are priorities.

Key Features

• Solid carbide construction for rigidity and wear resistance versus HSS alternatives
• Ball end geometry for 3D contouring, profiling, and radius floor finishing
• 2-flute design promotes chip clearance in slotting and plunge-entry cuts
• 30-degree right-hand helix balances cutting forces and surface finish
• Uncoated finish suitable for applications requiring post-use regrinding
• Single-end configuration — one active cutting end per tool

Compatibility

Designed for use in standard 5/16-inch ER collet chucks and end mill holders on vertical machining centers, CNC routers, and manual knee mills. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before seating or removing the tool from the holder. Ensure the shank is fully seated to the minimum insertion depth recommended for your collet or holder system to prevent pull-out under cutting loads. Inspect the cutting edges before use and do not run a chipped or damaged carbide tool.
