Hertel E8050048 Square End Mill 0.75in 2 Flute Hss Tin

Product Description

The HERTEL E8050048 is a double-end square end mill designed for milling operations in ferrous and non-ferrous materials. It carries a 0.75-inch cutting diameter, a 1.3125-inch length of cut, and a 5-inch overall length. Constructed from M7 high speed steel with a TiN (titanium nitride) finish, it delivers improved surface hardness and extended tool life compared to uncoated HSS tooling. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation. With two flutes and centercutting capability, this end mill handles both peripheral milling and plunge cutting. It is suited for use in manual mills, knee mills, and CNC machining centers.

This end mill fits standard milling applications in job shops, maintenance machining, and production environments. The 0.75-inch shank diameter seats directly in R8 collets, ER collet chucks, and end mill holders sized for 0.75-inch shanks. The regular-length geometry makes it a practical choice for shoulder milling, slotting, and profiling cuts where extended reach is not required. Both ends are usable, offering cost efficiency over single-end tooling. Machinists and tool-and-die professionals are the primary users of this type of end mill.

Key Features

• Double-end design allows use of both cutting ends, extending tool life per unit
• M7 high speed steel construction provides toughness in interrupted cuts
• TiN coating increases surface hardness and reduces built-up edge on the cutting lips
• 30-degree helix angle with spiral flutes for effective chip evacuation
• Centercutting geometry supports direct plunge entry into the workpiece
• Right-hand cut and right-hand flute configuration for standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard-duty cutting tool for manual and CNC milling machines accepting a 0.75-inch shank diameter via R8 collets, ER-style collet chucks, or end mill holders.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the collet or holder and torque the drawbar or nut to the machine manufacturer specification. Inspect both cutting ends for chipping or wear before use, and select the appropriate end for the operation.
