Hertel E1053040 Square End Mill 5/8 Inch 4 Flute Hss

Product Description

The HERTEL E1053040 is a double-end square end mill manufactured from M7 high speed steel. It features a 5/8-inch diameter cutting end with a 1-3/8-inch length of cut and a matching 5/8-inch shank diameter for a total overall length of 5 inches. With 4 spiral flutes at a 30-degree helix angle and a right-hand cut with right-hand flute direction, this tool is built for general-purpose milling operations in a variety of workpiece materials. The centercutting geometry allows plunge entry without a pre-drilled hole, expanding its range of applications in production and job shop environments. This tool is uncoated and suited for use by machinists and toolroom personnel working in manual or CNC milling applications.

This end mill is intended for use in conventional and CNC vertical milling machines, knee mills, and machining centers where a square-shoulder profile or slot is required. The double-end design doubles the usable life of the tool, making it an efficient choice for shops running high volumes of similar cuts. Applications include peripheral milling, slotting, and face milling in ferrous and non-ferrous materials typical of general machining work.

Key Features

• Double-end design provides two usable cutting ends for extended tool life
• Centercutting geometry allows direct plunge entry into the workpiece
• M7 high speed steel construction for good toughness and wear resistance
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Right-hand cut and right-hand flute direction for standard milling setups
• Uncoated finish suitable for use with cutting fluids in a range of materials

Compatibility

Designed as an OEM-style replacement or direct-use square end mill for standard 5/8-inch collet or end mill holder setups in vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by a machinist or toolroom technician using an appropriate end mill holder or collet sized to the 5/8-inch shank. Ensure the machine spindle is fully stopped and locked before changing tooling. Verify runout with a dial indicator after seating the tool, and confirm the tool holder is torqued to the machine manufacturer's specification before beginning a cut. Always follow applicable shop safety procedures and machine guarding requirements during tool changes.
