Maximum Up-time

You can count on the H25D to be running, day in and day out, whenever you need it. With only two moving parts, this hammer is your reliable breaker solution.

Compact Power

You can fit this hammer inside small spaces, but there's nothing small about the power you'll get. A high blow rate and constant blow energy deliver concrete-shattering power.

Easy to Maintain

Maintenance requirements are minimal, meaning you focus on getting work done, not working on your hammer. When maintenance is required, a quick-change bushing system gets you back to work quickly.

A Complete Solution

Only Cat gives you a complete solution: excavator, hammer and hydraulics seamlessly integrated for a one-stop solution. Plus, the enire package can be serviced by your Cat dealer, or any Cat dealer around the world.
