API 7K Certified Manual Tongs for Pipe Handling

Manual tongs are engineered for critical drilling operations, serving as precision tools for making up and breaking out drill pipes, casings, and tubing. By changing lug jaws and latch steps, operators can accommodate a wide range of tubular diameters without compromising grip strength. Designed and manufactured in strict compliance with API Spec 7K for drilling equipment, these tongs ensure both operational efficiency and safety.
