Gws 310203 Square End Mill 3/8 Inch 4 Flute Solid Carbide

Product Description

The GWS 310203 is a 4-flute solid carbide square end mill designed for high-performance material removal in demanding machining applications. With a 3/8 inch cutting diameter, 1/2 inch length of cut, and 2 inch overall length, this tool is built for precision work in tight tolerances. The AlCrO-MAX coating provides enhanced heat and wear resistance, extending tool life in difficult materials. The 38-degree upcut helix geometry promotes efficient chip evacuation and reduces heat buildup at the cutting edge. Centercutting capability allows for direct plunge cuts without pre-drilling. This tool is installed and operated by machinists and CNC tooling professionals.

The GWS 310203 is suited for milling operations across a broad range of workpiece materials including cast iron, non-ferrous metals, stainless steel, high-temp alloys, steel alloys, and titanium-group materials as indicated by material codes H, K, M, N, P, and S. It performs well in slotting, profiling, and contouring operations on vertical machining centers and CNC mills. The standard length configuration and 3/8 inch h6-tolerance shank make it compatible with common collet chuck and end mill holder setups used in production and job-shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance across hard and abrasive materials
• AlCrO-MAX coating for elevated thermal resistance and extended tool life
• 38-degree upcut helix angle promotes efficient chip evacuation and reduces recutting
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute configuration for standard CNC spindle operation
• h6 shank diameter tolerance for precise fit in collet chucks and end mill holders

Compatibility

Designed as a Series 2100 solid carbide square end mill with a 3/8 inch h6-tolerance shank, compatible with standard 3/8 inch collet chucks and end mill holders used on CNC vertical machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque the collet nut or set screw to the tool holder manufacturer's specification. Verify runout with a dial indicator after mounting and before initiating any cutting program.
