FuchsRohr® AluDrill™ is made by combining a high-strength-to-weight precision aluminum tube with conventional steel tool joints via a threaded thermal interference fit. The tube has an ISO compliant ACME thread at each end and connects to a steel tool joint with a matching thread on the back side of the tool joint. The tube body is tapered to provide improved strength in high torque areas, buckling resistance in compression and wear resistance at key points along the pipe geometry.
FuchsRohr® AluDrill™ is available in all common sizes from 4 up 6.625" with internal and external upsets for range 1 up to range 3 in lengths. Aluminum strength range from 50 to 80 ksi yield.
