Self-contained power hammer

That being said, I would only have a self contained air hammer, no external compressor hammers, no mechanical hammers. this type hammers will save much space and with good controllable. anyang ST power hammers always is welcomed.

In the self contained market, my first choice would be an new hammer with good performance and warranty. the cast frame will better than the fabricated designs, the cast frame air channel is cast in the metal, it’s volume will keep same when it works. But the fabricated design air channels are made from rubbers, i will not be shrink or dilate when it works, it will influence the air volume then not good for controlling performance.
