Hertel EM99924732 Ball End Mill 0.1875 in 3 Flute Carbide

Product Description

The HERTEL EM99924732 is a single-end ball end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, it delivers hardness and heat resistance suited for high-speed cutting in ferrous and non-ferrous materials. The tool features a 0.1875 inch mill diameter, a 0.625 inch length of cut, and a 30-degree right-hand helix. Three flutes provide efficient chip evacuation while maintaining surface finish quality. Machinists and CNC operators install this end mill in standard toolholders on vertical or horizontal machining centers.

This ball end mill is intended for contour milling, profiling, slotting, and 3D surface work on materials such as alloy steels, stainless steels, hardened steels, and cast irons where AlTiN coating offers a performance advantage. The 3/16 inch shank diameter matches the mill diameter, keeping the tool compact for tight-pocket and fine-detail work. Its right-hand cutting direction suits conventional CNC milling setups. The 2-inch overall length provides adequate reach without sacrificing rigidity in the cut.

Key Features

• Micrograin solid carbide substrate for improved wear resistance and edge sharpness
• AlTiN coating provides high-temperature hardness and oxidation resistance during dry or semi-dry cutting
• 3-flute geometry balances material removal rate with chip clearance in ferrous materials
• 30-degree right-hand helix reduces cutting forces and promotes smooth chip flow
• Ball-end profile suited for 3D contouring, radius profiling, and pocket finishing passes
• Single-end design with uniform 3/16 inch shank and mill diameter for direct collet or endmill-holder clamping

Compatibility

Designed for use in CNC machining centers, knee mills, and other rotating-spindle equipment that accepts a 3/16 inch shank end mill via collet, shrink-fit, or end mill holder tooling.

Installation Notes

End mills must be installed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before changing tooling. Ensure the shank is fully seated and properly torqued in the holder per the toolholder manufacturer specifications before running. Inspect the cutting edges for chips or wear before each use and replace the tool if edge integrity is compromised.
