Hertel E599924416 Ball End Mill 0.1719 in 4 Flute Carbide

Product Description

The HERTEL E599924416 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.1719 inch cutting diameter and a 0.3125 inch length of cut, this tool is suited for profiling, contouring, and slotting in tight geometries. The double-end configuration provides two usable cutting ends, extending tool life per unit. Right-hand cutting and right-hand spiral flute direction are standard for conventional CNC milling setups. Installed by machinists and toolroom operators, this end mill fits standard collet and end mill holders accepting a 3/16 inch shank.

This ball end mill is intended for use in CNC machining centers, knee mills, and manual milling machines where a small-diameter ball profile is required. Typical applications include die and mold work, finishing passes on curved surfaces, and contour milling of small features. The 4-flute spiral geometry supports higher feed rates and improved surface finish compared to 2-flute designs in harder materials. The uncoated bright finish makes it a straightforward choice for aluminum, brass, and similar non-ferrous materials, as well as softer steels where coating is not required.

Key Features

• Double-end design with two usable cutting ends for extended tool service
• 4-flute spiral configuration supports higher feed rates and better surface finish
• Solid carbide construction provides rigidity and wear resistance in demanding cuts
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation
• Uncoated bright finish suitable for non-ferrous metals and general-purpose milling
• 3/16 inch shank diameter fits standard collets and end mill holders

Compatibility

Designed as a general-purpose replacement or production ball end mill for CNC machining centers and manual mills accepting a 3/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully in the collet or holder to the recommended engagement depth before tightening — never grip on the fluted portion. Inspect the collet or holder for wear or runout before use, as excessive runout will reduce tool life and surface finish quality. Confirm spindle rotation direction matches the right-hand cutting specification before starting the machine.
