Stunner series include ST25BR” (2.5”), ST30BR (3”), ST35BR (3.5”), ST45PA (4.5”), STS45PA (4.5”), ST80D17 (8”) hammers. These are valveless type hammers designed for high performance at low operating pressures. The above mentioned hammers are designed with the suitable bit which does not have foot valve where it reduces the possibility of the hammer failure. By considering some of the factors like drilling diameters, air consumption and its application, the hammers are settled. The hole diameter and the air consumption changes depending upon the hammer.
