Guhring 9031790063500 Corner Chamfer End Mill 1/4 in 6 Fl

Product Description

The GUHRING 9031790063500 is a solid carbide corner chamfer end mill designed for high-performance finishing operations in ferrous and non-ferrous machining. It features a 1/4 inch diameter, six flutes, and a 45-degree helix angle that promotes efficient chip evacuation and surface finish quality. The tool carries a FIREX PVD coating, a TiAlN and TiN multilayer system that extends tool life in abrasive and high-temperature cutting conditions. With a 0.004 inch chamfer width and a 45-degree chamfer angle, it produces consistent edge breaks and chamfers in a single pass. It is centercutting, enabling plunging and ramp-down entry moves. Machinists and CNC programmers install this tool in vertical and horizontal machining centers for precision finishing work.

This end mill is suited for shouldering, slotting, ramp-down milling, helical interpolation, drill-mill operations, and plunging and recessing applications. Primary workpiece materials include steel, stainless steel, cast iron, and superalloys including titanium. Secondary materials include non-ferrous metals and hard materials. The right-hand flute direction and right-hand cutting direction make it compatible with standard CNC spindle configurations. It is classified as a regular-length, close-pitch tool from the Guhring Series 3179 line, targeting finishing-grade material removal with tight dimensional tolerances.

Key Features

• Solid carbide construction, material grade K40, for rigidity and wear resistance in hard materials
• FIREX PVD coating (TiAlN and TiN) for extended tool life in steel, stainless, and superalloy cuts
• Six flutes with 45-degree high-helix angle for smooth chip flow and improved surface finish
• Centercutting geometry allows plunging, ramp-down, and helical interpolation entry strategies
• 0.004 inch chamfer width at 45 degrees for consistent, repeatable edge breaking in one pass
• Straight-cylindrical shank with h6 tolerance for secure, low-runout toolholder fit

Compatibility

Designed for use with steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. Compatible with standard 1/4 inch straight-cylindrical toolholders. Part of Guhring Series 3179.

Installation Notes

This tool is installed by machinists and CNC tooling technicians in machining centers using a collet chuck or hydraulic toolholder sized for a 1/4 inch straight shank. Verify runout at the toolholder before production cuts to protect the fine chamfer edge. Confirm spindle direction and programmed entry strategy match the right-hand cutting geometry of this tool. Follow the machine builder and tooling manufacturer feed and speed guidelines for the specific workpiece material being machined.
