Gws 312325 Corner Radius End Mill 3/4 in 5 Flute Carbide

Product Description

The GWS 312325 is a solid carbide corner radius end mill engineered for demanding metal removal in steel, stainless steel, superalloys, and titanium. It features a 3/4-inch diameter, a 0.19-inch corner radius, and 5 flutes with a variable helix and variable index geometry. The AlCr (FX3) coating provides thermal resistance and edge durability during both roughing and finishing passes. The single-end, right-hand cut design with a straight-cylindrical shank is intended for use in end mill holders on CNC milling centers. This tool is suited for machinists and tooling professionals working in job shop, aerospace, and precision manufacturing environments.

The 312325 is designed for short-reach, high-performance milling applications where corner geometry control is critical. Its 1-inch length of cut and 2-inch reach length make it well-suited for shallow-to-moderate depth pocketing, profiling, and contouring in ferrous and exotic alloy materials. Secondary workpiece compatibility includes cast iron. The variable helix flute geometry helps reduce harmonic chatter, making it a practical choice for difficult-to-machine materials where tool stability matters.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard materials
• 0.19-inch corner radius reduces stress concentration at the cutting edge
• Variable helix and variable index geometry minimizes chatter during aggressive cuts
• AlCr (FX3) coating improves thermal performance in steel, stainless steel, superalloys, and titanium
• Centercutting design allows plunge milling entry
• Right-hand flute direction with straight-cylindrical h6-tolerance shank for precise holder fit

Compatibility

Designed for use with standard end mill holders. Primary workpiece materials are steel, stainless steel, superalloys, and titanium (material codes P, M, S). Secondary workpiece material is cast iron (material code K). Part of GWS Series 2213.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the end mill holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to confirm proper seating of the h6-tolerance shank. Follow machine tool manufacturer guidelines for RPM, feed rate, and depth of cut when programming tool paths for the target workpiece material.
