Hertel E103010802 Square End Mill 1-1/8 in 2 Flute Hss

Product Description

The HERTEL E103010802 is a 2-flute square end mill designed for general-purpose milling in machine shops and manufacturing environments. Manufactured from M7 high speed steel with a bright, uncoated finish, it offers reliable cutting performance across a range of ferrous and non-ferrous materials. Key dimensions include a 1.125-inch mill diameter, a 1.625-inch length of cut, and a 3.875-inch overall length. The 30-degree helix angle promotes efficient chip evacuation, while the centercutting design allows for direct plunge cuts without a pre-drilled entry point. Installation and use are handled by machinists and CNC operators on vertical mills and milling machines.

This end mill is suited for conventional and climb milling operations in job shops, toolrooms, and production environments. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. With a length of cut ranging from 1.5 to 2.0 inches, it handles moderate-depth slotting, profiling, and shoulder milling tasks. The bright finish is appropriate for general steel and non-ferrous alloy applications where a coating is not required.

Key Features

• 2-flute spiral flute geometry supports chip clearance in slotting and plunge operations
• Centercutting design allows direct plunge entry without a pilot hole
• 30-degree helix angle balances cutting efficiency and surface finish
• M7 high speed steel construction provides toughness across a range of work materials
• Right-hand cut and right-hand flute for use in standard milling spindles
• Bright, uncoated finish for versatile use without coating-specific limitations

Compatibility

Designed as a standard shank square end mill for use in collet chucks, end mill holders, and milling machine spindles accepting a 0.875-inch shank diameter.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the 0.875-inch shank in a properly sized end mill holder or collet and verify runout before cutting. Power down the spindle completely before changing tooling. Do not exceed the tool's rated depth of cut for the work material, and ensure adequate coolant or lubrication is applied as required by the machining operation.
