REVERSE CIRCULATION HAMMERS PRODUCTION FEATURES

The reverse circulation hammers is also called RC Hammer. It operates with a dual-wall drill pipe. High-pressure air flows down the annular space between the inner and outer pipes to power the RC drill bits, fracturing rock through percussive action. The debris-laden air then returns upward through the inner pipe's central channel, creating a reverse flow that isolates clean airflow and optimizes sample recovery and drilling efficiency.

As an industry-leading manufacturer, we offer a wide range of RC hammers crafted from high-strength alloy steel with advanced machining techniques. Our products guarantee durability and operational efficiency while being compatible with various rigs, catering to diverse working conditions, and delivering exceptional value to customers. We have different sizes of Reverse Circulation Hammer, ranging from 3'' to 5 1/2'', drilling hole diameter from 86mm-146mm. Among all our Reverse Circulation Hammers, RW53 is the most popular type, which has been widely accepted by customers from Australia and South Africa.
