The reinforced universal adapter with brass bushings is intended for converting a hand auger into a power auger, using a cordless screwdriver or a motor during the ice drilling. With a drill screwdriver and the universal adapter, ice is drilled easily, allowing spending a minimum effort and time on drilling. The brass bushings play the role of plain bearings. Compared to rolling bearings, they have a longer service life, are more wearresistant and also have increased anticorrosion properties. They withstand all the frictional forces and protect the adapter from wear, extending the product life under high loads. They also protect the adapter from moisture. The improved twostage design of the adapter output shaft has 19 mm and 22 mm diameters. Suitable for TORNADO, BURAN ice augers with the bit directly or with an extension; MOTOSHTORM bits with a bit directly or with an extension; ICEBERG ice augers with the bit directly or with an extension * The extensions are sold separately
