A range of durable augers are based on a threaded joint system. Items in this section may be interchanged and extended to any depth required. For increased versatility and convenience it may be preferred to have sectional augers. When joined with a bayonet and sleeve connection, the resulting unit has a working length of 1.25 metres. If required the augers may be further extended by either 0.5 or 1 metre increments.
