TAPER TAP

The Taper Tap is a special internal catch fishing tool that engages with dropped tubular objects such as drill pipes and tubes by tapping threads on the object surfaces. It is a highly effective tool in the fishing of dropped tubular objects with couplings especially when the tapered threads engaged with the fish couplings. The taper tap can be used for different fishing operations when equipped with left hand threaded or right hand threaded drill pipes and tools. The taper tap is made from high strength alloy steel, heat treated for maximum strength and ruggedness. The cutting threads are hardened (wicked) with cutting grooves to ensure proper tapping of threads on the fishes
