STH Series Power Hammer is a self contained forging hammers designed for use in blacksmith shops, welding and fabricating plants, maintenance facilities and schools. Bladesmiths will find the STH Series Power Hammer is best choices for Damascus work.Interchangeable upper and lower dies allow the user to form hot metal into an infinite variety of shapes. The basic machine comes with flat dies.
Optional Dies of ST Power Hammer
ST not only only supply flat die, also can supply kinds of optional dies include 1# Drawing die, 2# Fullering die, 3# Drawing / flat die, 4# Fullering / flat die, 5# Crown die, 6# Heavy Fullering die.

What’s Self Contained Power Hammer
What exactly does self contained mean? Instead of having a noisy, expensive, high pressure, high maintenance reciprocating air compressor to provide the air-motive force, STH Series Air Hammer use a low pressure, high volume system completely contained and integral to the machine. The motor drives a large flywheel via notched v-belts. The flywheel is connected via a pitman bearing and connecting rod to the rear piston. Basically, as the rear piston is pushed up, the front piston can come down, it’s depth of stroke determined by the position of the main valve, which is operated by the foot control. The result is excellent control, always enough air, less noise, greater reliability and a more productive and satisfying hammering experience.
The nature of air hammers provides a versatility unmatched by any other type of hammer. A wide range of stock sizes can be worked interchangeably. There are no springs or arms to adjust when going from wide to flat. We have successfully forged, .5 x 6″ mild steel, edgewise, as in the crown of this gate. Square A36 steel bar up to 2-1/2″ square is readily worked and larger sizes are possible. Power isn’t everything, though, and the ST power hammer is also a sensitive guy capable of light planishing blows or tapering .25″ rounds.
Low Working Temperature
Anyang ST power hammer use specially treatment on the cylinder and piston, make sure the friction surfaces have good finish, improve the controllable and reduce the working temperature.
