Gws 312005 Corner Radius End Mill 1-1/4 in 5 Flute Carbide

Product Description

The GWS 312005 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. With a 1-1/4 inch diameter, 4-1/2 inch length of cut, and a 1/4 inch corner radius, this tool delivers both roughing and finishing capability in a single pass. The 5-flute, variable helix and variable index geometry reduces chatter and improves surface finish in difficult materials. At 7 inches overall length and featuring a straight-cylindrical shank with h6 tolerance, it seats securely in standard end mill holders. The FX3 AlCr-based coating provides heat and wear resistance for extended tool life in hard and abrasive workpiece materials.

This end mill is suited for machining steel, stainless steel, superalloys, and titanium as primary materials, with cast iron as a secondary application. The long flute length and centercutting capability make it well-suited for deep-pocket milling, slotting, and profiling operations on CNC machining centers. It is intended for use in professional machine shop environments where tool life and surface consistency in hard materials are critical priorities.

Key Features

• Variable helix and variable index geometry reduces vibration and chatter during aggressive cuts
• 1/4 inch corner radius protects the cutting edge and improves corner strength in milled pockets
• 5-flute design increases feed rate capability compared to standard 4-flute tools
• Solid submicron carbide substrate for strength and wear resistance in ferrous and exotic alloys
• Centercutting geometry allows plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute, straight-cylindrical shank with h6 tolerance for precise holder fit

Compatibility

Designed for use with standard end mill holders. Primary workpiece materials include steel, stainless steel, superalloys, and titanium; secondary application includes cast iron.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling setup and safe tool change procedures. Ensure the spindle is fully stopped and the machine is in a safe state before installing or removing the tool. Seat the shank fully into the end mill holder and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before beginning the cutting operation.
