Guhring 9038760079440 Corner Radius End Mill 4 Flute

Product Description

The GUHRING 9038760079440 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining environments. With a 0.3125-inch mill diameter, a 0.031-inch corner radius, and four variable-helix flutes, this tool delivers both roughing and finishing capability in a single pass. The Super-A coating provides wear resistance and thermal stability, extending tool life in abrasive and hard materials. At 2.5 inches overall length with a 1.25-inch length of cut, it fits standard end mill holders and suits a wide range of CNC milling applications. Licensed machinists and tooling specialists are the primary end users for this series.

This end mill is engineered for use in steel, cast iron, superalloys, titanium, stainless steel, and hard materials. Its variable helix geometry reduces harmonic vibration during cutting, making it well suited for finishing passes on difficult alloys and for aggressive slotting or profiling in aerospace, die-and-mold, and general precision machining applications. The Series 3876 designation identifies it within the GUHRING catalog as a standard-length, straight-shank tool intended for use with end mill holders in CNC machining centers.

Key Features

• Variable helix and variable index geometry reduces chatter and improves surface finish
• 0.031-inch corner radius protects the cutting edge and extends tool life at the corner
• Right-hand cut, right-hand flute direction with single-end centercutting configuration
• Compatible with steel, cast iron, superalloys, titanium, stainless steel, and hard materials

Compatibility

Designed for use with standard end mill holders. Suitable for machining steel, cast iron, superalloys and titanium, stainless steel, and hard materials as primary and secondary workpiece materials per GUHRING Series 3876 specifications.

Installation Notes

Installation is performed by qualified machinists using standard end mill holders; verify holder bore and runout tolerance before seating the tool. Power down and lock out the spindle before changing tooling. Confirm proper torque on the set screw or collet per the holder manufacturer specification. Do not exceed the tool's rated length of cut when programming depth of pass.
