Hertel E299914103 Ball End Mill 11/32 in 2 Flute Hss

Product Description

The HERTEL E299914103 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in metal and other machinable materials. Ground from M7 high speed steel with a bright, uncoated finish, this tool delivers reliable performance in general-purpose machining applications. It features a 0.3438 inch (11/32 inch) cutting diameter, a 3/4 inch length of cut, and a 30-degree right-hand spiral helix. The 3/8 inch straight shank seats securely in standard end mill holders and collet chucks. With two flutes and a right-hand cutting direction, it is suited for finish passes and moderate material removal on mill, knee mill, and CNC machining center setups.

This ball end mill is intended for use in job shops, toolrooms, and production environments where general-purpose HSS tooling is specified. Common applications include slotting, pocketing, and contour work on steel, aluminum, cast iron, and plastics. The ball nose geometry produces a radiused profile on the workpiece, making it a standard choice for die and mold work, ramp entry, and blended surface machining. With a standard 2-1/2 inch overall length, it fits conventional tool-length requirements without extended reach clearance concerns.

Key Features

Compatibility

Designed as a standard single-end ball end mill for use in conventional and CNC milling machines accepting a 3/8 inch shank.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 3/8 inch shank fully into the collet or end mill holder and torque the retention hardware per the machine tool manufacturer specifications. Verify runout with a dial indicator before beginning a cut.
