Hertel GG030014 Square End Mill 7/32 in 2 Flute Cobalt

Product Description

The HERTEL GG030014 is a cobalt square end mill designed for precision milling operations in metalworking applications. Built from M42 cobalt high-speed steel, it offers strong heat and wear resistance compared to standard HSS tooling. The cutter measures 7/32 inch (0.2188 inches) in diameter with a 1/2 inch length of cut and a 3/8 inch shank diameter. A 30-degree right-hand helix promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish suits a wide range of ferrous and non-ferrous materials where a coating is not required. Machinists and tool-and-die professionals use this end mill for slotting, profiling, and peripheral milling on manual and CNC machines.

This single-end, 2-flute square end mill is suited for general-purpose milling in job shops, maintenance facilities, and production environments. The 2-flute geometry provides good chip clearance, making it a practical choice for plunge cuts and slot milling in softer steels, aluminum, and similar materials. The center-cutting design allows direct plunge entry without a pre-drilled pilot hole. Right-hand cutting direction matches standard spindle rotation on conventional vertical and horizontal milling machines.

Key Features

• M42 cobalt steel construction for improved heat resistance and tool life over standard HSS
• 2-flute, right-hand spiral geometry with 30-degree helix angle for efficient chip removal
• Center-cutting design allows direct plunge milling without a pilot hole
• Bright/uncoated finish suitable for ferrous and non-ferrous materials
• Single-end configuration with 3/8 inch shank for standard collet and end mill holder fitment
• Right-hand cutting direction compatible with standard CNC and manual mill spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling option for use in 3/8 inch end mill holders, collet chucks, or weldon-style holders on vertical and horizontal milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully powered down and locked out before changing tooling. Secure the shank firmly in a properly sized collet or end mill holder to the tool-holder manufacturer's recommended torque specification. Inspect the cutting edges for damage before each use and confirm correct spindle rotation direction matches the right-hand cutting geometry of this tool.
