Gws 122623 Corner Radius End Mill 1/4 in 7 Flute Carbide

Product Description

The GWS 122623 is a solid carbide corner radius end mill engineered for finishing operations in demanding materials. It features a 1/4-inch diameter, a 0.005-inch corner radius, and 7 flutes with a variable helix and variable index geometry. These design characteristics reduce harmonic vibration, improve surface finish, and extend tool life in high-hardness applications. The FX1 coating provides additional wear resistance across the cutting edge. This tool is a single-end, centercutting design suited for plunge entry and peripheral milling on CNC machining centers and manual mills used in production and job-shop environments.

This end mill is intended for finishing cuts in steel, cast iron, stainless steel, superalloys, titanium, and hard materials. The short flute length and 7-flute configuration make it well suited for high-feed finishing passes where chip load per tooth is reduced and surface finish requirements are tight. It fits standard end mill holders with a straight cylindrical shank and carries an h6 shank tolerance for precise holder engagement. Machinists working with hardened steels and difficult superalloy components will find the variable helix particularly effective at managing chatter.

Key Features

• 7-flute variable helix and variable index geometry reduces chatter and improves surface finish
• 0.005-inch corner radius protects the cutting edge and reduces stress concentration at corners
• Solid carbide submicron-grade material delivers hardness and wear resistance in tough workpiece materials
• FX1 coating adds surface protection for extended tool life in steel and hard materials
• Centercutting design allows direct plunge entry without pre-drilling
• Straight cylindrical shank with h6 tolerance for secure, precise fit in end mill holders

Compatibility

Designed for use with standard end mill holders. Suitable for finishing operations in steel, stainless steel, cast iron, superalloys, titanium, and hard materials as specified by GWS Series 1040.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before loading or removing tooling. Seat the shank fully into the end mill holder and verify runout with a dial indicator before cutting. Do not exceed manufacturer-recommended speeds and feeds for the workpiece material grade being machined.
