Hertel GG071028 Square End Mill 7/16 in 2 Flute Hss

Product Description

The HERTEL GG071028 is a square end mill designed for general-purpose milling operations in a wide range of ferrous and non-ferrous materials. Built from M7 high speed steel, this long-series end mill features a 7/16 inch cutting diameter, a 1-3/4 inch length of cut, and a 1/2 inch straight shank. The 42-degree helix angle promotes efficient chip evacuation and smooth cutting action. With two spiral flutes and a center-cutting geometry, it can be used for both plunge and peripheral milling. The uncoated finish makes it well suited for applications where re-sharpening is anticipated or where coating is not required.

This end mill is intended for use in vertical machining centers, knee mills, and manual or CNC milling machines. The long-series overall length of 3-3/4 inches provides added reach for applications requiring clearance beyond a standard-length tool. Right-hand cut and right-hand flute configuration follows conventional milling practice. It is typically installed and run by machinists and tool-and-die professionals in job shop, maintenance, and production environments where HSS tooling is the specified or preferred choice.

Key Features

• M7 high speed steel construction for toughness and re-sharpenability
• 42-degree helix angle for aggressive chip evacuation and reduced cutting forces
• Center-cutting design allows direct plunge entry into workpiece
• Two spiral flutes provide clearance and chip flow in slotting and profiling operations
• Long-series length type adds reach for deep-pocket and step milling applications
• Uncoated finish suitable for re-grinding and use with cutting fluids

Compatibility

Designed as a standard shank end mill compatible with 1/2 inch bore end mill holders, collet chucks, and side-lock holders used on vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque the retention mechanism per the holder manufacturer specification. Confirm runout with a dial indicator before beginning a cut.
