Guhring 9038760063520 Corner Radius End Mill 1/4in 4F

Product Description

The GUHRING 9038760063520 is a solid carbide corner radius end mill designed for high-performance milling in demanding shop environments. With a 1/4 inch diameter, a 0.015 inch corner radius, and 4 helical flutes, this tool is built for both roughing and finishing operations in a single setup. The Super-A coating extends tool life when cutting steel, cast iron, stainless steel, superalloys, titanium, and hard materials. Variable helix and variable index geometry reduce chatter and improve surface finish at the cutting edge. Overall length is 2.5 inches with a 1/4 inch straight-cylindrical shank.

This end mill is suited for CNC machining centers and manual knee mills where tight corner radii and edge quality are required. The 3/4 inch length of cut and center-cutting capability allow plunge entry and full-depth side milling on ferrous and exotic alloy workpieces. It is typically used by machinists and tool-and-die professionals working in precision part production, mold making, and aerospace component manufacturing. Compatible for use with standard end mill holders.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Super-A coating for extended tool life on steel, cast iron, stainless, superalloys, and titanium
• Variable helix and variable index geometry reduce vibration and improve finish
• 0.015 inch corner radius protects cutting edge and reduces workpiece stress concentrations
• Single-end, right-hand cut with right-hand flute direction
• Capable of both roughing and finishing material removal in one tool

Compatibility

Designed for use with standard end mill holders. Primary workpiece materials include steel, cast iron, superalloys, and titanium. Secondary workpiece materials include stainless steel and hard materials. Part of the GUHRING Series 3876.

Installation Notes

Installation is performed by a machinist using an appropriate end mill holder and torque wrench per the holder manufacturer specification. Ensure the machine spindle is fully stopped and the machine is in an e-stop or locked-out state before installing or removing any cutting tool. Verify shank diameter tolerance h6 is compatible with the holder bore before seating. Do not exceed the recommended depth of cut for the diameter and material being machined.
