Gws 122645 Corner Radius End Mill 5/8 in 7 Flute Carbide

Product Description

The GWS 122645 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding material applications. With a 5/8-inch cutting diameter and a 0.06-inch corner radius, this single-end, center-cutting tool delivers controlled edge engagement and reduced chipping at corners. The 7-flute, variable-helix, variable-index geometry supports smoother cutting action and reduced chatter, making it well suited for finishing passes on hard and difficult-to-machine materials. The close pitch flute arrangement maximizes chip removal efficiency during finishing cycles. The straight cylindrical shank is held to h6 tolerance for precise fit in standard end mill holders.

This end mill is intended for finishing operations on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is used in CNC machining environments where tight surface finish tolerances and controlled corner geometry are required. The short flute length and rigid solid carbide construction reduce deflection during light-depth, high-speed finishing passes. Machinists and toolroom professionals working in job shops, aerospace, or heavy equipment manufacturing will find this tool appropriate for demanding finishing applications.

Key Features

• 7-flute variable-helix, variable-index geometry reduces chatter and vibration during finishing
• 0.06-inch corner radius protects cutting edge and improves surface finish at part corners
• Solid carbide submicron-grade material provides hardness and wear resistance in tough alloys
• Center-cutting design allows plunge entry where required
• Right-hand cut and right-hand helical flutes for standard CNC spindle compatibility
• Straight cylindrical shank with h6 tolerance fits standard end mill holders securely

Compatibility

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

Installation Notes

Installation and tool changes should be performed with the machine spindle powered down and at a complete stop. Secure the shank fully within the end mill holder to the recommended grip depth before tightening. Confirm runout with a dial indicator after installation, as excessive runout will accelerate tool wear and degrade surface finish. Consult machine and toolholder manufacturer guidelines for appropriate clamping torque and collet selection.
