Product Description

?

Restore the hammering performance of your rotary hammer with this ram assembly, a critical component that transfers impact energy from the piston to the bit during operation. By delivering the force needed for drilling and chiseling in concrete, masonry, and other hard materials, it helps maintain powerful and consistent tool performance. A worn or damaged ram can result in reduced impact force or loss of hammer function, making replacement an important repair. Because this component is located within the hammer mechanism, refer to your tool's parts diagram or service manual to confirm the correct placement before installation. Sold individually.
