Value Collection C3SRH-3204 End Mill 1/2 in 3 Flute Cobalt

Product Description

The VALUE COLLECTION C3SRH-3204 is a single-end roughing finishing end mill designed for aggressive material removal and finishing passes in a single tool. Built from M42 cobalt high-speed steel, it handles demanding cuts in tough materials including stainless steel, titanium, and hardened alloys. The tool features a 60-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. With a 0.5000 inch mill diameter, 1.25 inch length of cut, and 3.25 inch overall length, it fits standard CNC machining centers and manual milling machines. Three flutes provide a balance of chip clearance and cutting edge strength for both roughing and light finishing work.

This end mill is suited for job shops, tool rooms, and production machining environments where a combination roughing and finishing tool reduces setup time and tool changes. The Weldon flat shank provides positive drive engagement in standard Weldon-style end mill holders, minimizing slippage during heavy cuts. The bright uncoated finish is appropriate for applications where coating interaction with the workpiece material is a concern, or where re-sharpening is anticipated. It is a right-hand cut, right-hand flute tool intended for conventional milling machine and CNC machining center use by machinists and toolmakers.

Key Features

• M42 cobalt construction for extended tool life in difficult-to-machine alloys
• 60-degree helix angle promotes aggressive chip evacuation and reduced cutting forces
• Three-flute geometry balances chip clearance with surface finish capability
• Weldon flat shank ensures positive drive and slip-free mounting in compatible holders
• Center-cutting design allows plunge entry into workpiece material
• Bright uncoated finish supports re-sharpening and compatibility with a wide range of materials

Compatibility

Designed for use in standard Weldon-style end mill holders with a 1/2 inch bore. Fits CNC machining centers and manual vertical milling machines that accept 1/2 inch shank tooling with a regular-length end mill profile.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe lockout state before loading or unloading the tool. Seat the Weldon flat against the set screw in the holder and torque the set screw according to the holder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, and never exceed the recommended speeds and feeds for the workpiece material and machine rigidity.
