Hertel E6250048 Ball End Mill 0.75 in 4 Flute Carbide Tin

Product Description

The HERTEL E6250048 is a single-end ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from solid carbide, it delivers the rigidity and wear resistance required for demanding cutting applications. The tool features a 0.75-inch diameter, a 1.5-inch length of cut, and a titanium nitride (TiN) coating that reduces friction and extends tool life in high-cycle production environments. With four flutes and a right-hand cutting direction, it produces smooth surface finishes while maintaining efficient chip evacuation. This end mill is sized for use in CNC machining centers and manual mills across job shops, toolrooms, and production floor settings.

This end mill is suited for profiling, contouring, and slotting operations where a full-radius cutting edge is required. The 0.75-inch shank diameter provides a secure, concentric grip in standard end mill holders and collet chucks. Its 4-inch overall length makes it appropriate for applications requiring moderate reach without sacrificing rigidity. The TiN coating is well matched to cutting steel, cast iron, aluminum, and similar workpiece materials at elevated surface speeds.

Key Features

• Solid carbide construction for high rigidity and thermal resistance
• TiN coating reduces friction and improves wear resistance during extended cutting cycles
• Four right-hand flutes with right-hand helix for efficient chip evacuation
• Ball end geometry enables full-radius profiling and 3D contouring
• Single-end design with 0.75-inch shank for use in standard end mill holders
• Fixed helix and fixed index geometry for predictable, consistent cutting performance

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.75-inch shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank to the full recommended insertion depth in the holder and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a cutting pass.
