Gws 310727 Corner Radius End Mill 1/8 in 4 Flute Carbide

Product Description

The GWS 310727 is a solid carbide corner radius end mill designed for precision milling in demanding metal-cutting applications. With a 1/8 inch diameter, 0.03 inch corner radius, and 4 flutes, this tool is built for both roughing and finishing operations in a single setup. The AlCr coating provides heat resistance and extended tool life when cutting ferrous and exotic materials. The centercutting geometry enables plunge entry, and the 3/4 inch extended reach makes it suitable for workpiece features that require clearance beyond a standard shank length. Licensed machinists and CNC operators working in job shop and production environments will find this tool well-suited to high-demand milling work.

This end mill is intended for use on steel, stainless steel, superalloys, titanium, and cast iron workpieces. The Series 2105 design targets applications where tight corner radii and consistent surface finishes are required in hard and abrasive materials. The short flute length of 3/16 inch combined with a 3/4 inch reach and 3 inch overall length provides stability and rigidity during cuts. It mounts in standard end mill toolholders and is compatible with CNC machining centers and manual mills set up for 1/8 inch shank tooling.

Key Features

• 0.03 inch corner radius for blended edge transitions and reduced stress concentrations at workpiece corners
• Solid carbide submicron-grade construction for rigidity and wear resistance in ferrous and exotic alloys
• AlCr coating classification provides thermal and oxidation resistance during high-speed cutting
• Centercutting design allows direct plunge milling without a pre-drilled entry point
• Variable helix and variable index geometry helps reduce chatter and harmonic vibration
• Right-hand flute direction and right-hand cutting orientation for standard CNC spindle operation
• Extended reach of 3/4 inch allows access to recessed features without tool interference

Compatibility

Designed for use with standard end mill toolholders accepting a 1/8 inch straight-cylindrical shank with h6 tolerance. Primary workpiece materials include steel, stainless steel, superalloys, and titanium. Secondary workpiece material is cast iron.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the tool. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear on a small-diameter carbide tool. Follow toolholder manufacturer torque and retention specifications when tightening set screws or collets.
