Hertel GH03210819 Square End Mill 1-1/8 in 6 Flute Hss

Product Description

The HERTEL GH03210819 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 with a titanium nitride (TiN) finish, it offers improved surface hardness and wear resistance compared to uncoated HSS tooling. The 1.125-inch cutting diameter and 6-flute spiral geometry produce a smoother finish and allow higher feed rates on conventional machining centers and manual mills. The right-hand cut, right-hand flute configuration is standard for most milling applications. At 0.504 pounds, this is a solid, shop-ready tool sized for medium-duty cutting work.

This end mill is suited for use in machine shops, tool rooms, and maintenance environments where conventional milling of steel, cast iron, and similar materials is performed. The 1.75-inch length of cut accommodates moderate-depth slotting, profiling, and peripheral milling operations. The 0.75-inch shank diameter fits standard ER and side-lock tool holders found on vertical milling machines, CNC machining centers, and Bridgeport-style knee mills. Its regular length classification keeps it rigid and minimizes deflection during cutting.

Key Features

• M7 high speed steel construction for strength and toughness in general milling
• TiN coating increases surface hardness and extends tool life versus uncoated HSS
• 6-flute design improves finish quality and supports higher feed rates
• 30-degree helix angle spiral flute for efficient chip evacuation
• Right-hand cut and right-hand flute — standard orientation for most milling setups
• Non-centercutting geometry — not suitable for direct plunge cuts

Compatibility

Designed as a standard single-end square end mill for use in milling machines and machining centers accepting a 0.75-inch shank diameter tool holder.

Installation Notes

Installation and use of this end mill should be performed by qualified machinists familiar with milling operations. Always power down and lock out the machine spindle before mounting or removing tooling. Ensure the shank is fully seated and clamped in the tool holder to the manufacturer-recommended engagement depth before cutting. This tool is non-centercutting and must not be used for plunge milling without a pilot hole or ramping entry path.
