Hertel E299914102 Ball End Mill 9/32 in 2 Flute Hss

Product Description

The HERTEL E299914102 is a single-end ball end mill designed for milling contoured surfaces, slots, and complex 3D profiles in a wide range of metals and engineered materials. It is ground from M7 high speed steel and features a bright, uncoated finish suitable for general-purpose cutting applications. The mill measures 0.2813 inches (9/32 inches) in diameter with a 9/16-inch length of cut and a 2-3/8-inch overall length. The 30-degree right-hand spiral helix promotes efficient chip evacuation and stable cutting action across a range of feeds and speeds.

This end mill is suited for job shop, tool room, and production environments where ball-nose profiling, radius milling, and die-sinking operations are performed. The 3/8-inch shank diameter fits standard ER collet chucks, end mill holders, and side-lock holders on vertical machining centers, knee mills, and CNC routers. With two flutes and a right-hand cutting direction, it performs well in both ferrous and non-ferrous applications at moderate material removal rates.

Key Features

• M7 high speed steel construction for toughness and wear resistance in general machining
• Ball-nose geometry for contour milling, 3D profiling, and radius slot work
• 30-degree right-hand spiral helix for effective chip evacuation
• Bright, uncoated finish compatible with cutting oils and flood coolant
• Single-end design with 2-flute configuration for chip clearance in deeper cuts
• 3/8-inch shank fits widely available standard toolholders

Compatibility

Designed as a standard single-end ball end mill for use in any machine tool accepting a 3/8-inch round shank; consult toolholder specifications to confirm runout and gripping requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in an e-stop or lockout state before loading or changing tooling. Verify collet or toolholder bore matches the 3/8-inch shank diameter and that the tool is seated to the proper gauge-line depth before tightening. Inspect the cutting edges for chips or damage before each use, and set feeds and speeds according to the work material and machine rigidity.
