Guhring 9069860127090 Corner Radius End Mill 5 Flute

Product Description

The GUHRING 9069860127090 is a solid carbide corner radius end mill designed for demanding metal removal in steel, stainless steel, cast iron, superalloys, and titanium. Built on the Series 6986 platform, it features a 0.5-inch mill diameter, a 0.12-inch corner radius, and five helical flutes with a medium-high helix angle for both roughing and finishing operations. The nano-A coating provides elevated surface hardness and thermal resistance, extending tool life in high-wear applications. This is a single-end tool with a right-hand cutting direction and right-hand flute spiral.

This end mill is suited for machining steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. It is appropriate for milling operations requiring a controlled corner radius — typical uses include profiling, contouring, and shoulder milling on CNC machining centers. The Weldon flat shank is compatible with standard end mill holders. It is not designed for center cutting and is not configured for coolant-through delivery.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard material applications
• nano-A coating for thermal resistance and extended tool life
• 0.12-inch corner radius with a tolerance of -0.002 to 0.002 inches for consistent edge geometry
• Five helical flutes configured for both roughing and finishing passes
• Weldon flat shank for secure seating in end mill holders
• Right-hand cutting and flute direction with normal pitch and medium-high helix

Compatibility

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

Installation Notes

This tool is installed by a machinist or toolroom technician in a CNC or manual milling setup. The machine spindle must be fully stopped and the tool changer or collet chuck depressurized before tool changes. Confirm that the end mill holder matches the 0.5-inch shank diameter and that the Weldon flat is properly aligned with the set screw. Verify runout after installation and before initiating a cut cycle.
