Hertel GG030060 Square End Mill 15/16 in 2 Flute Hss

Product Description

The HERTEL GG030060 is a square-end, single-end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from M7 high speed steel, this end mill features a 15/16-inch cutting diameter, a 1-1/2-inch length of cut, and a 3/4-inch shank diameter with an overall length of 3-3/4 inches. The 30-degree spiral helix and two-flute configuration promote efficient chip evacuation and smooth cutting action. It is uncoated and centercutting, allowing both peripheral and plunge cuts. Machinists and toolroom professionals working in manual or CNC milling environments will find this a dependable general-use tool.

This end mill is suited for use in vertical mills, knee mills, and CNC machining centers where standard tolerances and moderate material removal rates are required. The right-hand cut and right-hand flute orientation match conventional spindle setups. Its centercutting geometry makes it capable of slot milling and pocket entry without a pre-drilled pilot hole. Typical applications include profile milling, slotting, and facing operations in steel, aluminum, and similar workpiece materials common in job shops, toolrooms, and maintenance environments.

Compatibility

Designed as a standard single-end square end mill with a 3/4-inch shank, compatible with collet chucks, end mill holders, and other standard toolholding systems accepting that shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout. Always confirm the spindle is fully stopped and the machine is powered off before inserting or removing end mills. Ensure the shank is clean and fully seated in the holder to the recommended engagement depth before securing. Inspect the cutting edges for chips or wear before each use.
