Hertel E1053056 Square End Mill 7/8 in 4 Flute Hss

Product Description

The HERTEL E1053056 is a double-end, four-flute square end mill manufactured from M7 high speed steel. It carries a 7/8 inch cutting diameter, a 1-7/8 inch length of cut, and a 6-1/8 inch overall length with a matching 7/8 inch shank diameter. The 30-degree spiral flute geometry promotes efficient chip evacuation and reduces heat buildup during milling. The uncoated finish makes it straightforward to resharpen in the field. Right-hand cut and right-hand flute orientation are standard for conventional vertical and horizontal milling setups. Machinists and tool-and-die professionals are the primary users of this tool.

This end mill is suited for general-purpose milling operations in job shops, maintenance facilities, and production environments. Its centercutting capability allows it to plunge directly into workpiece material, enabling slotting, profiling, and pocket milling without a pre-drilled entry point. The regular-length classification fits standard milling machine and machining center spindle setups. It is appropriate for use on ferrous and non-ferrous materials within the performance range of M7 high speed steel.

Key Features

• Double-end design extends usable tool life before replacement
• Centercutting geometry enables direct plunge entry into workpiece material
• 30-degree helix angle promotes smooth chip flow and reduced cutting force
• M7 high speed steel construction provides toughness and grindability
• Right-hand cut and right-hand flute for standard milling machine compatibility
• Uncoated finish simplifies resharpening on conventional grinding equipment

Compatibility

Designed as a general-purpose replacement or production end mill for standard milling machines and machining centers accepting a 7/8 inch straight shank.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully in a collet or end mill holder rated for the shank diameter before use, and verify runout with a dial indicator prior to cutting. Power down and lock out the machine spindle before changing or indexing the tool. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds based on workpiece material.
