The ION X features a new single piece cast bottom design as well as a 5 amp-hour XC5 lithium ion battery. The new cast bottom creates perfectly even blade engagement and results in unbelievably smooth drilling, re-drilling, and break through. Drill up to 1600 inches of ice per charge with the all-new XC5, a five amp-hour battery with over 60% more capacity than previous ION batteries. LED Lights on the bottom of the motor to help assist drilling in the dark or in your dark house! The smoothest auger you'll ever own!
