Kennametal’s Mill 4-11 is specially engineered to achieve excellent surface quality and higher metal removal rates in shoulder milling applications. Its unique design allows you to apply the tool in multiple passes (step down) with outstanding results.

From roughing to finishing operations, Mill 4-11 is applicable in a wide range of materials: steel, cast iron, stainless steel, non-ferrous materials, and high-temp alloys.

Kennametal’s Mill 4-12KT requires up to 15% less horsepower, enabling increased feed rates even on 40 taper machines. Its proprietary insert design features a triangular shaped margin that provides unprecedented stability in steel and cast-iron applications and its minimal axial runout delivers excellent floor finish.

With seven grades, seven corner radii and a depth-of-cut range up to .472" (12mm), the Mill 4-12^KT can bring new versatility to your shoulder milling applications.
