Hertel E8032124 Square End Mill 1-3/8 in 6 Flute Hss Tin

Product Description

The HERTEL E8032124 is a single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from M7 high speed steel and finished with a titanium nitride (TiN) coating, it delivers extended tool life in production and job-shop environments. The cutter measures 1.375 inches in diameter with a 2-inch length of cut and runs six spiral flutes at a 30-degree helix angle. Right-hand cut and right-hand flute geometry make it compatible with standard vertical and horizontal milling setups. This tool is installed and run by machinists, toolmakers, and CNC operators working in metalworking facilities.

This end mill fits regular-length milling applications where a larger diameter cutter is needed for profiling, slotting, and peripheral milling. The 1-inch shank diameter suits standard R8, CAT, BT, or direct-mount collet systems commonly found in knee mills and machining centers. The non-centercutting geometry means it is intended for side milling and profiling passes rather than plunge cutting. With a 4.5-inch overall length, it maintains rigidity in typical setups without excessive overhang.

Key Features

• M7 high speed steel construction for toughness in interrupted cuts and general milling
• TiN coating reduces friction and increases surface hardness for longer tool life
• Six flutes provide a higher feed-per-revolution potential compared to four-flute designs
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Right-hand cut and right-hand flute geometry for standard spindle direction
• Non-centercutting design suited for side milling and profiling operations

Compatibility

Designed as a direct-fit replacement or standard tooling selection for milling machines accepting a 1-inch straight shank, including knee mills and vertical machining centers with appropriate collet or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Secure the shank to the full recommended engagement depth in the collet or end mill holder to prevent pullout under cutting loads. Verify runout with a dial indicator after mounting, especially at this diameter, before beginning a production run.
