Hertel E299914077 Square End Mill 15/32 in 2 Flute Cobalt

Product Description

The HERTEL E299914077 is a cobalt square end mill designed for milling operations in ferrous metals, stainless steels, and other tough materials. It features a 15/32 inch (0.4688 inch) cutting diameter with a 1 inch length of cut and a 1/2 inch shank diameter. The 2-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Built from M42 cobalt high-speed steel, this end mill delivers heat and wear resistance beyond standard HSS tooling. The overall length of 3-3/8 inches fits standard toolholders used in knee mills, vertical machining centers, and CNC routers. It arrives uncoated and ready for use with standard cutting fluids.

This end mill suits general-purpose milling applications in job shops, maintenance departments, and production environments. The centercutting design allows plunge milling in addition to peripheral and slot cuts. Right-hand cut and right-hand flute configuration make it compatible with conventional spindle rotation on standard milling machines. The 2-flute layout is well-suited for slotting and pocketing in softer ferrous and non-ferrous materials where chip clearance is a priority.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the 1/2 inch shank in a properly sized collet or end mill holder and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before production use. Always bring spindle to a full stop before changing tooling, and follow shop safety protocols for eye and chip protection.
