Hertel E5250014 Ball End Mill 0.2188 in 4 Flute Carbide

Product Description

The HERTEL E5250014 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.2188-inch cutting diameter, a 0.625-inch length of cut, and a 4-flute configuration, this tool delivers smooth material removal and fine surface finishes in ferrous and non-ferrous materials. The 30-degree helix angle promotes efficient chip evacuation while reducing cutting forces. Solid carbide construction provides the rigidity and wear resistance required for demanding CNC milling operations. This end mill is suited for machinists, tool-and-die makers, and CNC operators working in job shops, aerospace, or general manufacturing environments.

This ball end mill is commonly used for contour milling, 3D profiling, slotting, and finishing passes on curved surfaces and complex geometries. The single-end design with a right-hand cutting and right-hand flute direction makes it compatible with standard vertical and horizontal CNC machining centers. The 0.25-inch shank diameter fits standard collets and toolholders found in most shop environments. Its uncoated carbide surface is well suited for use with cutting fluids in general-purpose milling applications.

Key Features

• 0.2188-inch ball nose cutting diameter for precision contouring and profiling
• 4-flute design for improved surface finish and efficient material removal
• Solid carbide construction for rigidity and extended tool life
• 30-degree helix angle promotes effective chip evacuation and reduced heat buildup
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Uncoated finish suitable for general-purpose machining with cutting fluid

Compatibility

Designed as an OEM-style replacement and standard-fit ball end mill for CNC machining centers and manual mills accepting a 0.25-inch shank diameter collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or chuck to the recommended engagement depth per the toolholder manufacturer. Verify runout with a dial indicator before commencing cuts, particularly for finish profiling operations.
