Gws 312746 Corner Radius End Mill 3/4 in 7 Flute Carbide

Product Description

The GWS 312746 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding metal-cutting applications. With a 3/4 inch cutting diameter, 7 flutes, and a 0.12 inch corner radius, this tool delivers superior surface finishes while reducing chipping at the cutting edge. The FX3 AlCr coating provides enhanced heat resistance and wear protection, making it well suited for extended tool life in difficult-to-machine materials. It features right-hand flute direction and right-hand cutting action with a high-helix, close-pitch configuration optimized for finish passes. Licensed machinists and tool-and-die professionals are the primary users of this end mill.

This end mill is intended for finishing operations on steel, stainless steel, superalloys, titanium, and cast iron. The Series 2215 single-end design with a straight-cylindrical shank fits standard end mill holders and is suited for CNC machining centers handling tight-tolerance finish work. The 1-5/8 inch length of cut and 4 inch overall length make it appropriate for moderate-depth finishing passes in vertical and horizontal machining setups.

Key Features

• 3/4 inch cutting diameter with 0.12 inch corner radius for edge protection and improved finish quality
• 7-flute, close-pitch helical design optimized for finishing in ferrous and high-temp alloy materials
• FX3 AlCr coating for elevated temperature resistance and extended tool life
• Centercutting geometry allows plunge entry as part of finishing routines
• Right-hand cut and right-hand helix with h6 shank tolerance for precise holder fit
• Submicron carbide grade supports rigidity and edge retention in superalloys and titanium

Compatibility

Designed for use with standard end mill holders. Primary workpiece materials include steel, stainless steel, superalloys, and titanium. Secondary workpiece material is cast iron.

Installation Notes

Installation is performed by qualified machinists following shop safety and tooling protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 3/4 inch straight-cylindrical shank fully in the end mill holder and torque the retention mechanism to the holder manufacturer's specifications. Verify runout with a dial indicator before beginning the cut to protect both the tool and the workpiece surface finish.
