Hertel GG99914124 Square End Mill 1 in 2 Flute Hss

Product Description

The HERTEL GG99914124 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M7 high speed steel, it offers good wear resistance and toughness for slotting, profiling, and peripheral milling applications. The cutter measures 1 inch in diameter with a 1-1/2 inch length of cut and a 1/2 inch shank diameter, giving it a compact, rigid geometry suited for light to moderate material removal. A 30-degree helix angle promotes smooth chip evacuation, and the centercutting design allows direct plunge entry into the workpiece without pre-drilling.

This end mill is a regular-length tool intended for CNC machining centers, manual knee mills, and similar spindle-driven equipment. It is well suited for ferrous and non-ferrous materials where an uncoated HSS cutter is preferred, such as aluminum, mild steel, and brass. The 2-flute configuration provides generous chip clearance, making it appropriate for slotting cuts and applications where chip evacuation is a priority. It ships individually and is used by machinists, tool and die makers, and production shop personnel.

Key Features

• M7 high speed steel construction for toughness and wear resistance
• 1 inch cutting diameter with 1-1/2 inch length of cut
• 2-flute spiral design for efficient chip clearance during slotting and profiling
• 30-degree helix angle promotes smooth cutting action and reduces chatter
• Centercutting geometry allows direct plunge milling without pilot hole
• Right-hand cut and right-hand flute for standard spindle operation
• Uncoated finish suitable for applications where coating is not required or preferred

Compatibility

Designed as a standard single-end square end mill with a 1/2 inch straight shank, compatible with any spindle or collet system accepting a 1/2 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the collet or chuck. Verify that the shank is fully seated and properly torqued in the holder per the toolholder manufacturer specifications. Inspect the cutting edges for damage before each use and confirm appropriate speeds and feeds for the workpiece material.
