Guhring 9038910047000 Corner Chamfer End Mill 4.7mm

Product Description

The GUHRING 9038910047000 is a solid carbide corner chamfer end mill designed for high-performance metal removal in demanding machining applications. Built with three flutes and a variable helix geometry, it reduces chatter and improves surface finish during roughing operations. The 4.7 mm cutting diameter is paired with a 13 mm length of cut and a 0.05 mm chamfer width at a 45-degree chamfer angle. FIREX PVD coating - a TiAlN and TiN multilayer system - extends tool life when cutting steel, stainless steel, superalloys, and titanium. The straight cylindrical 6 mm shank and extended reach design make it compatible with standard collet toolholders.

This end mill is suited for CNC machining centers and milling machines used in precision metalworking environments. Its centercutting capability supports shouldering, slotting, ramp-down entry, helical interpolation, drill milling, and plunging and recessing operations. The coarse pitch and right-hand flute direction make it well matched for steel and stainless steel workpieces, with secondary capability on cast iron and non-ferrous metals. The 4.50 mm neck diameter and 18 mm reach length allow access to confined features without sacrificing rigidity.

Key Features

• 4.7 mm cutting diameter with 13 mm length of cut for precise slot and shoulder work
• Variable helix geometry reduces vibration and chatter during roughing passes
• FIREX PVD coating (TiAlN and TiN) for extended tool life on steel, stainless, and superalloys
• Centercutting design enables ramp-down, plunge, and helical interpolation entry strategies
• Extended reach with 18 mm reach length and 4.50 mm neck diameter for recessed feature access
• Single-end, right-hand cut with straight cylindrical shank for standard collet compatibility

Compatibility

Designed for use on steel, stainless steel, superalloys, and titanium as primary workpiece materials, with secondary suitability for cast iron and non-ferrous metals. Fits standard 6 mm collet toolholders. Part of the GUHRING Series 3891 corner chamfer end mill family.

Installation Notes

This tool is installed by machinists and CNC toolroom technicians using a 6 mm precision collet or hydraulic chuck. Ensure the machine spindle and toolholder are clean and within specified runout tolerances before seating the shank. Confirm programmed feeds, speeds, and entry strategies match the workpiece material and depth of cut before engaging the spindle. Handle carbide tooling carefully to avoid chipping the cutting edges during setup.
