Guhring 9031670127000 Ball End Mill 0.5 in 4 Flute Carbide

Product Description

The GUHRING 9031670127000 is a solid carbide ball end mill engineered for precision contouring, profiling, and 3D surface milling in demanding machining environments. Built on the Series 3167 platform with an ultra fine grain carbide substrate, this tool delivers consistent edge integrity and wear resistance across extended production runs. The 0.5 inch cutting diameter and 2 inch length of cut provide reach for deep-cavity work, while the FIREX coating reduces friction and thermal buildup at the cutting zone. A 30-degree helix angle promotes smooth chip evacuation and stable cutting action. This end mill is installed by machinists and CNC operators working in job shops, tool rooms, and production facilities.

This tool is suited for milling cast iron, steel alloys, non-ferrous metals, and certain high-temperature alloys. The primary workpiece material codes cover K (cast iron), M (stainless steel), N (non-ferrous), and P (steel), with secondary capability in S (heat-resistant superalloys). The long-series overall length of 4.5 inches makes it a fit for applications requiring extended reach beyond a standard-length end mill, such as deep pockets or contoured die and mold surfaces.

Key Features

• Solid carbide construction with ultra fine grain substrate for edge strength and dimensional stability
• FIREX coating reduces heat transfer and extends tool life in ferrous and mixed-material applications
• 4-flute, single-end ball nose geometry for contouring, profiling, and finish passes
• 30-degree right-hand spiral flute for efficient chip evacuation and reduced cutting forces
• Long-series length (4.5 inches OAL) provides extended reach for deep-cavity and mold work
• Mill diameter tolerance h10 and shank diameter tolerance h6 for consistent toolholder fit

Compatibility

Designed as a direct-fit replacement or production cutting tool for CNC machining centers and manual mills using standard 1/2 inch diameter toolholders including collet chucks, shrink-fit holders, and end mill holders compatible with a 1/2 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and the tool path program verified before changing tooling. The 1/2 inch shank should be seated to the minimum insertion depth specified by the toolholder manufacturer, and runout should be checked at the cutting tip before production. Avoid side-loading the ball nose tip during plunge entry; use ramping or helical interpolation entry strategies to protect edge integrity.
