Abstract
Embodiments provide apparatuses and methods for excavation and drilling, particularly reverse circulation hammers and bits. Reverse circulation hammers and bits manufactured in accordance with various embodiments may help to prevent fatigue and breaking of the bit during a drilling operation, may prevent clogging of return holes, may provide higher efficiency drilling operations, and may provide modular bit designs that may be interchanged to suit a particular drilling operation.
