Guhring 9067590063540 Corner Radius End Mill 1/4 in

Product Description

The GUHRING 9067590063540 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. Built on the RF100 Series 6759 platform, it features a 1/4 inch diameter, a 0.031 inch corner radius, and a variable helix with variable index geometry that reduces harmonic vibration during cutting. The nano-Si coating provides enhanced wear resistance and thermal stability across a broad range of workpiece materials. With four flutes and a right-hand cutting direction, this tool is suited for both roughing and finishing operations in a single setup.

This end mill is intended for use in CNC machining centers and manual mills where tight tolerances and surface finish quality are critical. It is engineered for ferrous and non-ferrous applications including steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. The straight cylindrical shank is compatible with standard end mill holders. Machinists and tooling specialists in production shops, job shops, and aerospace component manufacturing will find this tool well suited to high-value workpieces that require consistent edge geometry.

Key Features

• Variable helix and variable index geometry reduces chatter and improves surface finish
• nano-Si coating for extended tool life across ferrous and non-ferrous materials
• 0.031 inch corner radius with tolerance of -0.002 to 0.002 inches for repeatable edge geometry
• Four flutes with right-hand helical flute direction for efficient chip evacuation
• Solid carbide extra fine micrograin substrate for rigidity and wear resistance
• Single-end configuration with straight cylindrical shank for use with standard end mill holders

Compatibility

Designed for use with standard end mill holders. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials per material codes P, M, K, S, N, and H.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and the tool holder is clean and free of debris before mounting. Confirm runout with an indicator after clamping to verify concentricity within acceptable limits. Follow the tooling manufacturer and machine builder guidelines for appropriate feed rates and speeds for the workpiece material being machined.
