Select air drill upgrade.  Blue drill is standard with the tool kit. 

BEST OPTION: Upgrade to the orange drill which is almost identical to the Sioux 1412 drill in size, weight, very smooth trigger operation and low noise level. 

Or upgrade to the red Sioux drill. The older style Sioux 1412 drills are no longer manufactured.

These upgrade options are only valid with RV tool kit purchase and not for separate purchase.
