The MKT #6 is a small air hammer. It is becoming increasingly rare but parts are still available. It can be used with a flat anvil or cupped anvil (for timber pile). There are a number of adapters that can be used with this hammer such as a boot for stabilization, pants for driving sheet pile, or fork lift adapters so that the hammer can be mounted on a forklift. It weighs 2,970 pounds and delivers 2,500 foot pounds of energy.
