Hertel E202002402 Ball End Mill 0.375 in 4 Flute Hss

Product Description

The HERTEL E202002402 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in ferrous and non-ferrous materials. Built from M7 high speed steel with a bright uncoated finish, it runs a 0.375-inch diameter with a 0.75-inch length of cut and a 30-degree right-hand spiral helix. The 4-flute geometry delivers a balance of chip evacuation and surface finish quality. Overall length is 2.5 inches with a 0.375-inch straight shank. This tool is installed by machinists and CNC operators working in job shop, tool room, and production environments.

This end mill is suited for milling slots, pockets, contours, and complex 3D profiles in mild steel, alloy steel, aluminum, and similar materials. The regular-length configuration makes it appropriate for standard-depth applications where rigidity and chatter resistance are priorities. The right-hand cutting direction is compatible with conventional right-hand spindle setups on vertical and horizontal milling machines and CNC machining centers. It is a practical general-purpose tool for operators needing a reliable ball nose geometry at this diameter range.

Key Features

• 0.375-inch ball nose diameter for contour and 3D profile milling
• M7 high speed steel construction for toughness in interrupted cuts
• 4-flute spiral design balances chip clearance and finish quality
• 30-degree right-hand helix reduces cutting forces on workpiece
• Bright uncoated finish suited for use with cutting fluids
• Single-end, regular-length design maximizes rigidity in standard-depth setups

Compatibility

Designed as an OEM-style replacement or direct substitute for standard 3/8-inch shank ball end mills in right-hand spindle milling machines and CNC machining centers accepting straight-shank toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the toolholder collet or end mill holder and torque set screws according to the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a production cut, as excessive runout accelerates wear on HSS tooling.
