Guhring 9069880095260 Corner Radius End Mill 3/8in 5 Flute

Product Description

The GUHRING 9069880095260 is a solid carbide corner radius end mill designed for demanding material removal in steel, stainless steel, cast iron, superalloys, and titanium. Built in the Series 6988 lineup, it features a 3/8 inch mill diameter, five helical flutes, and a 0.06 inch corner radius that reduces stress concentrations at the cutting edge. The nano-A coating provides enhanced wear resistance and thermal stability, extending tool life in high-productivity roughing and finishing passes. With an extra-long 3-1/2 inch overall length and 1-1/2 inch length of cut, this end mill reaches deeper features without requiring additional tooling setups.

This end mill is suited for CNC machining centers in job shop and production environments where mixed-material work is common. The right-hand cut and right-hand flute direction pair with standard end mill holders using a straight-cylindrical 3/8 inch shank. It handles both roughing and finishing operations in a single tool, making it a practical choice for machinists working with ferrous and non-ferrous alloys, hardened materials, and difficult-to-machine superalloys and titanium. A normal pitch and medium-high helix angle support chip evacuation across these material types.

Key Features

• Solid carbide construction for rigidity and edge retention in hard and abrasive materials
• nano-A coating for improved wear resistance and heat management at the cutting zone
• 0.06 inch corner radius reduces edge chipping and improves surface finish at corners
• Five flutes with helical geometry support both roughing and finishing in a single pass
• Extra-long 3-1/2 inch OAL reaches deeper features with a straight-cylindrical shank for secure clamping
• Corner radius tolerance of -0.002 to 0.002 inches for consistent dimensional accuracy

Compatibility

Designed for use with standard end mill holders accepting a 3/8 inch straight-cylindrical shank. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout. Power down and lock out the spindle before inserting or removing the tool. Verify shank engagement depth meets the toolholder minimum grip length to prevent pullout under load. Inspect the cutting edges for chipping or coating wear before each use and replace the tool when wear exceeds acceptable limits.
