Guhring 9067590095240 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The GUHRING 9067590095240 is a solid carbide corner radius end mill designed for high-performance metal removal across a broad range of ferrous and non-ferrous workpiece materials. Built on the RF100 platform with a variable helix and variable index geometry, this single-end tool delivers both roughing and finishing capability in one setup. The 0.031-inch corner radius reduces stress concentration at the cutting edge, extending tool life in demanding applications. Applied with a nano-Si coating, the cutter resists heat and wear during cuts in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is sized for use in standard end mill holders.

This end mill fits production machining environments where a single tool must handle multiple material types and operations. With a 3/8-inch diameter, 7/8-inch length of cut, and 2.5-inch overall length, it is well suited for profiling, slotting, and contouring in aerospace, die and mold, and general metalworking applications. Right-hand cutting and right-hand flute direction are standard. The extra fine micrograin carbide substrate and Series 6759 designation indicate a premium-grade tool intended for CNC machining centers using proper workholding and coolant strategies.

Key Features

• Solid carbide construction with extra fine micrograin substrate for rigidity and edge retention
• nano-Si coating provides thermal and wear resistance in ferrous and hard-material cuts
• Variable helix and variable index geometry reduces chatter and improves surface finish
• 0.031-inch corner radius with a tight tolerance of -0.002 to 0.002 inches extends corner edge life
• Single end, right-hand cut, helical flutes with straight-cylindrical shank for standard end mill holder compatibility
• Rated for roughing and finishing in steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials

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 material codes P, M, K, S, N, and H.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the straight-cylindrical shank in a properly sized end mill holder, ensuring adequate gripping length and runout within machine tolerances before cutting. Power down and lock out the spindle before tool changes. Do not exceed the tool manufacturer's recommended speeds and feeds for the specific workpiece material and depth of cut being used.
