well it seems like this project has dragged on... i couldnt find the wood auger bits at all. recently spotted some on ebay and also some in harbor freight.
$6.99 free shipping

$15.99 minus 20% with coupon($12.79) + tax no shipping($13.91). i would buy 2 packs and use the 2 smaller ones on the excavator and the bigger ones for other stuff maybe

about $28 either way...
anyone know of any other place to get these?
