Hertel E599924502 Ball End Mill 0.4375 in 2 Flute Carbide

Product Description

The HERTEL E599924502 is a solid carbide ball end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.4375 inch cutting diameter and a 0.875 inch length of cut, this two-flute tool delivers efficient material removal in ferrous and non-ferrous workpieces. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. The uncoated solid carbide construction provides rigidity and wear resistance suited to general-purpose contouring, slotting, and profile milling. Machinists and tool-and-die professionals working on CNC mills and manual knee mills will find this a reliable workhorse for finish and semi-finish passes.

This end mill is suited for use in job shops, production machining cells, and toolroom applications where accurate three-dimensional contours and pocket radii are required. The ball nose geometry produces a full radius at the tip, making it the appropriate choice for contoured surfaces, ramp milling, and cavity work. The single-end configuration and standard 0.4375 inch shank diameter allow direct mounting in collet chucks, end mill holders, and shrink-fit tooling sized for 7/16 inch shanks.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding cuts
• 0.4375 inch mill diameter with matching 0.4375 inch shank diameter for balanced holding
• 0.875 inch length of cut accommodates moderate-depth profiling and slotting
• 30-degree right-hand helix promotes chip flow and reduces heat buildup
• Uncoated finish suitable for general-purpose milling and regrinding
• Two-flute geometry allows improved chip clearance in softer materials and slotting applications

Compatibility

Designed as a standard single-end ball end mill with a 0.4375 inch shank, compatible with collet chucks, end mill holders, and shrink-fit toolholders sized for 7/16 inch shanks on CNC and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per applicable shop safety procedures. Ensure the shank is seated to the proper depth in the toolholder and that the collet or set screw is torqued according to the toolholder manufacturer's specifications. Inspect the cutting edges and shank for damage before mounting. Runout should be checked at setup to avoid premature tool wear or part inaccuracy.
