Hertel E1030026 Square End Mill 13/32 in 2 Flute Hss

Product Description

The HERTEL E1030026 is a 2-flute square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Manufactured from M7 high speed steel, this uncoated end mill features a 30-degree right-hand spiral flute with centercutting capability, allowing it to plunge directly into a workpiece as well as perform peripheral and slot milling. The 13/32-inch cutting diameter is paired with a 3/8-inch straight shank, making it compatible with standard collet chucks and end mill holders. At 0.08 pounds, it is a lightweight tool suited for benchtop and knee mills as well as CNC machining centers requiring a reduced-diameter finishing or profiling pass.

This end mill is used in job shops, maintenance machining, and production environments where M7 HSS tooling is preferred over carbide for its toughness and resistance to chipping in interrupted cuts. The 13/16-inch length of cut supports slot and pocket milling within typical depth-of-cut ranges for this diameter class. Its right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling on vertical mills. It is installed and used by machinists and tool-and-die professionals working with manual or CNC milling equipment.

Key Features

• 13/32-inch (0.4063-inch) cutting diameter with 13/16-inch (0.8125-inch) length of cut
• M7 high speed steel construction for toughness in interrupted and general-purpose cuts
• Centercutting design allows direct plunge entry into the workpiece
• 30-degree helix angle spiral flute for efficient chip evacuation
• Right-hand cut, right-hand flute configuration for standard milling operations
• Uncoated finish suitable for use with cutting fluids on a wide range of materials

Compatibility

Designed as an OEM-style replacement or standard tooling option for vertical milling machines and CNC machining centers accepting a 3/8-inch straight shank end mill holder or collet chuck.

Installation Notes

This end mill is installed by machinists using a standard collet chuck or end mill holder sized for a 3/8-inch shank. Ensure the milling machine spindle is fully powered down and the quill is locked before changing tooling. Verify runout with a dial indicator after seating the tool to confirm proper holder engagement. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
