The Signature Series thread design allows connection and disassembly with only 1-1/2 turns, significantly faster than with thinner thread designs. Because the threads are thicker and more durable than traditional threads, they can also withstand tough use in the field. The rounded bail design is easy to use. The auger bits have been modified to speed the augering process even more. Except for the Dutch Auger and Open-Face Clay Auger, each auger has high carbon steel bits with tungsten carbide hard surface edges, a stainless steel cylinder, and a carbon steel bail. The Dutch Auger and Open-Face Clay Auger are made of carbon steel.
