DetailsThe 12" auger extension adds length to your K-Drill Ice Auger System and is easy to install with an Allen Wrench In conditions of thick ice, be sure to clear the hole of of ice several times to assure excess ice shavings do not build-up in the hole which will bind the auger and make it hard to lift out once the hole is complete. Extension helps when cutting through thick ice (beyond 3 foot) or when you need extra length when drilling in a permanent fish house or when you just don't want to bend over so for when drilling through thick ice.
