Jeffrey Machine manufactures CFA hex couplers for continuous flight auger systems where connection accuracy affects drilling performance. A precise hex interface reduces play at the joint, which supports steadier torque transfer and more consistent tool response under load. Because we build in-house, you can specify the fit and configuration your equipment requires for reliable changeovers. Jeffrey Machine also offers CFA couplings for alternate interfaces.
