Yoder Power Hammer

Yoder Power Hammer

The Yoder K-90-M Power Hammer is the premier power hammer built for bending, forming and planishing light gauge shapes of sheet metal.  They have numerous applications, including automotive parts, aerospace  and custom sheet metal, and are used extensively in the aerospace industry as well as the build of custom cars and choppers, where perfect balance in a power hammer is desirable.  The perfect balance of this hammer is a feature that insures a long life, smooth running and stability; vibration being reduced to the lower possible degree.  Compared to competitor machines, which are a cheapened knock off of the Yoder LK-90-M, the K-90-M offers a larger throat, die area and roughly double the rated blow capacity, enabling the K-90-M Power Hammer to be used for a wider range of large aerospace and automotive parts, as well as greater gauge range capability.  The Yoder Power Hammer is furnished with a specially designed pedestal.
