The AMS Soil Auger Kits are Complete and Compact. Signature series Mini Soil Auger Kits are available in 3 1/4" auger size. AMS Signature Series augers, extensions & cross handles feature a heavier thread than the standard 5/8" NC thread AMS augers. The signature series thread is more robust and will connect with only 2-1/2 turns. The signature series extensions are also gold zinc plated for added rust resistance. The Kits Include: One regular and one mud auger, four extensions (3' or 4') and a cross handle, packed in a flexible poly-canvas case for easy carrying, transport and storage.
