Gws 121328 Corner Radius End Mill 3/4 in 5 Flute Carbide

Product Description

The GWS 121328 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. Built to the Series 1035 standard, it features a 3/4-inch cutting diameter, a 0.06-inch corner radius, and 5 flutes with a variable helix and variable index geometry. These design elements reduce chatter and harmonics during aggressive cuts. The FX1 coating provides enhanced wear resistance and heat dissipation, extending tool life in ferrous and hard materials. At 4 inches overall length with a 1-1/2-inch length of cut, this end mill is suited for both roughing and finishing operations in a single setup.

This end mill is intended for use in CNC machining centers and vertical mills across job shop and production environments. It is center-cutting, allowing plunge entry, and features right-hand flute direction and right-hand cutting. Primary workpiece materials include steel, cast iron, superalloys, titanium, and hard materials. Secondary applications cover stainless steel. It is compatible with standard end mill holders and is designed for short-reach applications where rigidity is critical. Machinists and tooling engineers working in aerospace, automotive, and heavy manufacturing will find this tool well-suited to tight-tolerance work.

Key Features

• 5-flute variable helix and variable index design reduces chatter and vibration during high-load cutting
• 0.06-inch corner radius protects cutting edges and improves surface finish on workpiece corners
• Solid submicron carbide construction delivers hardness and thermal stability in difficult alloys
• Center-cutting geometry allows direct plunge entry without pre-drilling
• FX1 coating enhances wear resistance across steel, cast iron, superalloys, and hard materials
• Straight-cylindrical shank with h6 tolerance ensures consistent clamping in end mill holders

Compatibility

Designed for use with standard end mill holders. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials as designated by material codes P, K, S, H, and M.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the end mill holder and verify runout with a dial indicator before production cutting. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
