Guhring 9067590095220 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The GUHRING 9067590095220 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining applications. It features a 3/8 inch mill diameter, a 0.015 inch corner radius, and 4 flutes with a variable helix and variable index geometry. The nano-Si coating reduces friction and extends tool life when cutting ferrous and non-ferrous workpiece materials. With a 7/8 inch length of cut and 2.5 inch overall length, this single-end tool fits standard end mill holders and suits both roughing and finishing operations on CNC mills and machining centers.

This end mill is suited for machining steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. The Series 6759 RF100 platform is built for right-hand cutting with a right-hand flute direction. The variable helix geometry helps reduce chatter and harmonic vibration during aggressive cuts, making it a practical choice for production environments where surface finish and dimensional control matter on difficult alloys.

Key Features

• 0.015 inch corner radius with tolerance of -0.002 to 0.002 inches for controlled edge geometry
• Variable helix and variable index design reduces chatter in interrupted and continuous cuts
• nano-Si coating for improved wear resistance across steel, stainless, and superalloy materials
• Extra fine micrograin solid carbide substrate for edge integrity at elevated cutting speeds
• Right-hand cut, right-hand helix, single end configuration with straight-cylindrical shank
• 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. Primary material codes P, M, K, S and secondary material codes N, H per ISO classification.

Installation Notes

Installation is performed by a machinist or CNC tooling technician using a compatible end mill holder sized to the 3/8 inch straight-cylindrical shank. Verify runout and holder clamping torque according to the holder manufacturer specifications before cutting. Ensure the machine spindle is fully stopped and locked out before tool changes. Do not exceed the manufacturer-recommended speed and feed parameters for the target workpiece material and coating type.
