Walt's Drill Bit and Nut Driver Holder is handmade of solid oak and ponderosa pine and has a space-saving footprint of only 13 inches by 3.75 inches and is 2.25 inches tall. There are 69 receptacles on four levels for your collection of quarter-inch drill bits and nut drivers. Going up, each level accommodates drill bits with slightly longer shanks—in other words, each level has a receptacle that's a little deeper than the 'step' below. You'll wonder how you ever did without this handy organizer. If you use three-eighths or half-inch bits and drivers, you can order a holder designed for the size you use.
