Hertel E5018016 Ball End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The HERTEL E5018016 is a solid carbide ball end mill designed for precision milling operations in metal, composites, and engineering plastics. With a 0.25 inch cutting diameter and a 1.5 inch length of cut, this single-end tool handles slotting, profiling, and contour milling in a wide range of CNC machining applications. The 2-flute configuration and 30-degree right-hand spiral helix promote efficient chip evacuation, while the bright uncoated carbide substrate delivers consistent edge sharpness in dry or lightly lubricated cutting conditions. Machinists and tool-and-die professionals reach for this geometry when finishing hardened or tough alloy workpieces where edge integrity matters.

This ball end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills running at appropriate speeds and feeds for carbide tooling. The 0.25 inch shank diameter fits standard ER, TG, and set-screw style collet chucks. Its 4 inch overall length provides enough reach for moderate-depth cavity work without excessive deflection. Center-cutting capability allows direct plunge entry, making it practical for ramping and helical interpolation routines in die work, mold making, and precision component manufacturing.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding milling applications
• Ball nose geometry enables 3D contour milling, profiling, and radial blending passes
• 2-flute, right-hand spiral design promotes chip clearance in slotting and pocket milling
• 30-degree helix angle balances cutting forces and surface finish quality
• Center-cutting design supports direct plunge entry and helical ramping
• Bright uncoated finish suited for non-ferrous metals and general-purpose carbide cutting conditions

Compatibility

Designed as an OEM-style solid carbide ball end mill compatible with standard 1/4 inch collet chucks and tool holders used in CNC vertical machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully within the collet or tool holder to the manufacturer-recommended engagement depth before tightening. Verify spindle runout with a dial indicator before committing to finish passes on critical surfaces. Always confirm correct spindle speed and feed rate for the workpiece material and cutting depth before starting the cut.
