Hertel E699924424 Ball End Mill 0.375 in 4 Flute Carbide

Product Description

The HERTEL E699924424 is a solid carbide ball end mill designed for high-performance milling operations in ferrous and non-ferrous materials. With a 0.375-inch cutting diameter and a 4-flute configuration, this double-end tool delivers efficient chip evacuation and a smooth finish on contoured surfaces. The TiN (titanium nitride) coating increases surface hardness and reduces friction, extending tool life in production environments. The right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling setups. Machinists and tooling specialists in machine shops, fabrication facilities, and production environments rely on this geometry for 3D profile work, die and mold applications, and finishing passes.

This ball end mill is suited for use on vertical machining centers, CNC mills, and manual knee mills where a 3/8-inch shank is appropriate. The double-end design provides two usable cutting ends per tool, offering extended tool life from a single piece. A 0.75-inch length of cut (LOC) and 3.5-inch overall length (OAL) make this configuration practical for moderate-depth cavities and profiling work where reach is needed without sacrificing rigidity.

Key Features

• Solid carbide construction for superior rigidity and wear resistance compared to HSS tooling
• TiN coating reduces friction and improves tool longevity in production runs
• 4-flute design balances chip clearance with surface finish quality
• Double-end configuration provides two cutting ends per tool
• Right-hand cut and right-hand flute direction for standard CNC and manual mill compatibility
• 0.75-inch length of cut suited for moderate-depth profiling and finishing passes

Compatibility

Designed for use in standard 3/8-inch collets, end mill holders, or shrink-fit toolholders on CNC vertical machining centers and conventional milling machines. No specific OEM or machine family compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and machine power is off before changing tooling. Secure the shank fully within the holder to the recommended engagement depth per the toolholder manufacturer guidelines, and verify runout with a dial indicator before production use. Always confirm spindle speed and feed rate are appropriate for the workpiece material and tool diameter before initiating a cut.
