Hertel E202004802 Ball End Mill 0.75in 4 Flute Hss

Product Description

The HERTEL E202004802 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in metal cutting applications. Built from M7 high speed steel with an uncoated finish, it features a 0.75-inch cutting diameter and a 1.625-inch length of cut. The 4-flute, right-hand spiral configuration provides efficient chip evacuation and a smooth surface finish. With a 30-degree helix angle and regular-length geometry, this tool suits production shops and tool rooms where HSS tooling is preferred for its toughness and regrindability. Licensed machinists and CNC operators are the primary users.

This ball end mill is suited for milling ferrous and non-ferrous metals in both manual and CNC machining centers. Its 0.75-inch shank diameter matches standard collet and end mill holder tooling, and the 3.875-inch overall length keeps it rigid in typical setup configurations. Applications include profiling dies and molds, machining radii, and blending contours in general-purpose shop work. The uncoated HSS construction makes it a practical choice where regrinding is part of the tooling workflow.

Key Features

• M7 high speed steel construction for toughness and regrind capability
• 4-flute, right-hand spiral design for smooth cutting action and chip clearance
• 30-degree helix angle suited for profiling and contour passes
• Ball nose geometry enables 3D surface milling and radius work
• Uncoated finish compatible with standard cutting fluids and oils
• Single-end configuration with 0.75-inch shank for standard toolholders

Compatibility

Designed as a standard single-end ball end mill with a 0.75-inch shank diameter, compatible with conventional end mill holders, collet chucks, and milling machine spindles accepting 3/4-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Set tool runout within acceptable limits using a dial indicator before commencing cuts. Do not exceed the recommended depth of cut or feed rate for HSS tooling in the workpiece material being machined.
