Gws 311812 Corner Radius End Mill 0.75in 5 Flute Carbide

Product Description

The GWS 311812 is a single-end, solid carbide corner radius end mill designed for high-performance metal removal in demanding machining applications. It features a 0.75 inch mill diameter, a 2.25 inch length of cut, and a 0.12 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life. The 5-flute, variable-helix, variable-index geometry improves chip evacuation, reduces harmonic vibration, and supports both roughing and finishing passes in a single tool. The FX3 AlCr-based coating adds thermal resistance and surface hardness for extended tool life at elevated cutting speeds. Licensed machinists and CNC operators working in job shops or production environments will find this tool suited to aggressive material removal cycles.

This end mill is engineered for cutting steel, stainless steel, superalloys, titanium, and cast iron. Its variable-helix flute profile and submicron carbide grade make it effective in interrupted cuts and difficult-to-machine workpiece materials. The straight cylindrical shank with h6 tolerance mounts directly in standard end mill holders. Series 2205 geometry targets shops running modern CNC machining centers where tool rigidity and consistent surface finish are required across multiple operations.

Key Features

• 0.75 inch mill diameter with 0.12 inch corner radius for reduced edge chipping and improved corner strength
• 5-flute variable-helix, variable-index design reduces chatter and vibration during aggressive cuts
• Centercutting geometry allows plunge milling entry
• FX3 AlCr coating provides thermal resistance and extended wear life in ferrous and high-temp alloys
• Submicron solid carbide grade supports both roughing and finishing material removal types
• Right-hand cutting and right-hand flute direction for use with standard CNC spindle rotation

Compatibility

Designed for use with standard end mill holders accepting a 0.75 inch straight cylindrical shank with h6 tolerance. Primary workpiece materials include steel, stainless steel, superalloys, and titanium; secondary material is cast iron.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify holder runout and clamping torque per the holder manufacturer specifications before beginning a cutting cycle. Confirm coolant-through is not required for this tool, as it is rated for external coolant or dry cutting only.
