Guhring 9030910063520 Corner Radius End Mill 1/4in 6FL

Product Description

The GUHRING 9030910063520 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding machining environments. Built to Series 3091 specifications, it features a 1/4 inch diameter cutting head with six helical flutes and a 0.015 inch corner radius that reduces stress concentrations at part edges. The FIREX coating provides elevated heat resistance and extended tool life when cutting ferrous and exotic materials. With a 3/4 inch length of cut and a 2.5 inch overall length, this single-end tool suits close-tolerance finish passes on CNC machining centers and manual mills. It is installed and used by machinists and tool-and-die professionals working in precision metal fabrication and production environments.

This end mill is engineered for finishing cuts on steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. The high helix geometry and close pitch flute configuration promote chip evacuation and surface finish quality in tight-tolerance applications. The straight cylindrical shank with a 1/4 inch diameter seats directly into standard end mill holders. It is suited to both job-shop and production runs where consistent radius geometry and edge integrity are required across repeated setups.

Key Features

• 6-flute helical design with close pitch for improved surface finish in finishing operations
• 0.015 inch corner radius reduces edge chipping and stress concentration on workpiece corners
• FIREX coating enhances heat resistance and wear resistance on ferrous and exotic alloys
• Solid carbide construction provides rigidity and dimensional stability at elevated cutting speeds
• Right-hand cutting and right-hand flute direction for standard CNC and manual mill spindle compatibility
• Straight cylindrical shank for direct mounting in end mill holders without additional adapters

Compatibility

Designed for use with standard end mill holders. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials.

Installation Notes

Installation is performed by machinists using a standard end mill holder torqued per the holder manufacturer specifications. Ensure the spindle is fully stopped and the machine is locked out before tool changes. Verify runout at the cutting diameter after installation to protect the corner radius geometry. Do not use this tool as a drill or apply axial loads beyond the rated length of cut.
