Hertel E699924738 Ball End Mill 0.4375 in 3 Flute Carbide

Product Description

The HERTEL E699924738 is a solid carbide ball end mill designed for precision milling operations in metal cutting and finishing applications. With a 0.4375 inch (7/16 inch) mill diameter and a 1 inch length of cut, this three-flute tool delivers efficient chip evacuation and smooth surface finishes on ferrous and non-ferrous materials. The micrograin carbide substrate provides wear resistance and edge retention. A 30-degree helix angle balances cutting efficiency with rigidity. TiN coating adds surface hardness and reduces friction at the cutting edge. This tool is used by machinists and tooling professionals in CNC and manual milling operations.

This ball end mill suits contour milling, profiling, slotting, and finishing passes in die, mold, and general machining work. The single-end, right-hand cutting configuration with right-hand flute direction makes it compatible with standard spindle setups. The 7/16 inch shank diameter fits common collets and end mill holders found in vertical and horizontal machining centers. Its 2.75 inch overall length provides adequate reach for most standard workpiece setups without sacrificing rigidity.

Key Features

• Solid micrograin carbide construction for extended tool life in hard and abrasive materials
• TiN (Titanium Nitride) coating reduces friction and increases surface hardness at the cutting edge
• Three-flute geometry balances chip removal with rigidity for finish and semi-finish passes
• 30-degree right-hand helix angle for efficient cutting action and smooth chip flow
• Single-end design with 0.4375 inch ball nose for accurate contour and radius milling
• Variable helix and variable index: No — consistent pitch for predictable cutting performance

Compatibility

Designed as a direct-fit replacement for standard 7/16 inch shank ball end mill applications. Fits collets, end mill holders, and shrink-fit holders sized for a 7/16 inch shank diameter in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Seat the shank fully in the collet or holder and torque the retention hardware to the tool holder specification. Verify runout with a dial indicator before beginning a cutting program.
