Hertel EM99924741 Ball End Mill 0.625 in 3 Flute Carbide

Product Description

The HERTEL EM99924741 is a single-end ball end mill designed for precision milling operations in metal and alloy workpieces. Built from micrograin solid carbide, it offers rigidity and wear resistance suited to demanding cutting conditions. The tool measures 0.625 inches in diameter with a 1.25-inch length of cut and a 3.5-inch overall length. Three right-hand flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. An AlTiN coating improves heat resistance and extends tool life during high-speed or dry machining. This end mill is installed and operated by machinists and CNC programmers in job shops, production facilities, and toolroom environments.

This ball end mill is suited for profiling, contouring, and 3D surface milling in ferrous and non-ferrous materials. The ball nose geometry generates smooth radii and blended surfaces on molds, dies, and complex contoured parts. The 0.625-inch shank diameter matches standard collet and end mill holder sizes common in vertical machining centers and CNC mills. Single-end construction keeps the tool compact and balanced for tight-tolerance finish passes.

Key Features

• Micrograin solid carbide construction for rigidity and extended tool life
• AlTiN coating for elevated heat resistance during high-speed or dry cutting
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Ball nose geometry for profiling, contouring, and 3D surface work
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Single-end design with matched 0.625-inch shank and cutter diameter

Compatibility

Designed for use in standard 0.625-inch collets, end mill holders, and hydraulic chucks on vertical machining centers and CNC milling machines requiring a single-end ball nose carbide end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder and torque the retention hardware to the machine manufacturer's specification using calibrated tooling. Verify runout with a dial indicator before committing to a production cut.
