Professional Design Nw Rod - 8 Inch DTH Hammer – TDS Detail:

1 The latest contemporary rock drilling theory is adopted to design the internal structure size of the dth hammer, so that the dth hammer can get the most ideal energy transfer, and the single impact work is large and the rock drilling speed is faster.
2 The unique taper reducer design can reduce the lifting resistance and greatly reduce the failure of the dth hammer when the drill rig is lifted up in case of debris and clay jamming during drilling.
3 In order to prevent dust pollution in the drilling operation, the main parts of the product adopt a special computer program-controlled heat treatment process to facilitate the addition of a small amount of high-pressure water in the compressed air for wet rock drilling to protect the health of the operator.
