Guhring 9067590079440 Corner Radius End Mill 5/16 in

Product Description

The GUHRING 9067590079440 is a solid carbide corner radius end mill designed for high-performance milling in demanding material applications. Built on the RF100 series platform, it features a 5/16 inch diameter, a 0.031 inch corner radius, and a variable helix with variable index geometry that reduces chatter and improves surface finish across both roughing and finishing passes. The 4-flute configuration and nano-Si coating provide wear resistance and thermal stability during aggressive cuts in ferrous and non-ferrous materials. At 2.5 inches overall length with a 3/4 inch length of cut, this tool fits standard end mill holders used in CNC machining centers and manual mills alike.

This end mill is suited for machining steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. It is a single-end, straight-shank tool intended for use in production and job-shop environments where consistent corner geometry and coating performance are required across a range of workpiece materials. The RF100 series is commonly specified by machinists and CNC operators working in aerospace, general metalworking, and precision manufacturing applications where edge integrity and tool life matter.

Key Features

• Solid carbide construction in extra fine micrograin grade for rigidity and edge retention
• nano-Si coating for enhanced wear resistance and heat management
• Variable helix and variable index geometry reduce vibration during cut
• 0.031 inch corner radius with a tight tolerance of -0.002 to 0.002 inches
• Right-hand flute direction and right-hand cutting for standard spindle use
• Rated for both roughing and finishing material removal in a single tool

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 as defined by ISO material codes P, M, K, S, N, and H.

Installation Notes

Installation is performed by machinists or CNC setup technicians using a compatible end mill holder with the appropriate 5/16 inch bore. Ensure the machine spindle is fully stopped and the tool is properly seated and torqued per the holder manufacturer specifications before running. Verify runout with a dial indicator after tool change to confirm the shank diameter tolerance is within acceptable limits for the application. Follow all machine guarding and lockout procedures before changing tooling.
