MAXBIT designed this 25-inch extension for use with their Garden Hole Digging Drill Bits. This extension features a powder-coated steel construction. It works with either the 4-inch or 6-inch bit and includes all the hardware needed for installation.
The MAXBIT 25-Inch Extension allows you to dig planting holes from a standing position. It fits any 3/8-inch drill; however, MAXBIT recommends using an 18-volt or higher drill.
