Surface shot blasting treatment for dth rock drilling bits
Surface shot blasting treatment for down-the-hole rock drilling bits is a process that uses high-speed projection of metal particles (e.g., steel shots) to clean, strengthen, or increase surface roughness. It is widely applied in metalworking, casting, or surface treatment industries. Unlike **shot peening** (which focuses on improving material fatigue resistance), shot blasting emphasizes cleaning or pre-treatment functions.
