Frequently Asked Questions

What is the OSG ball end mill 404-0938-BN11 used for?

This OSG carbide ball end mill is used for contouring, profiling, and 3D machining of hardened steels and tool steels. The ball nose geometry enables smooth surface finishes in die/mold, aerospace, and general metalworking applications. The TiAlN coating extends tool life at elevated cutting temperatures.

What are the specifications of the OSG 404-0938-BN11 ball end mill?

The OSG 404-0938-BN11 is a general purpose carbide ball end mill with a 3/32" mill diameter, 5/16" length of cut (LOC), and 1-1/2" overall length (OAL). It has 4 flutes and a TiAlN coating. The shank diameter matches the mill diameter for standard toolholding.

Where to buy the OSG 404-0938-BN11 ball end mill worldwide?

How to select the correct OSG ball end mill for your application?

Select the OSG ball end mill based on workpiece material, required surface finish, and machine rigidity. For hardened steels, the TiAlN coated 4-flute design provides good chip evacuation and heat resistance. Match the 3/32" mill diameter to your desired radius and stepover. Use rigid toolholding to minimize deflection.
