The Maxbit 7804974 5 x 12 in. Steel Digging Drill Bit - Yellow WRQ4Y_VW986

Product details:

Fit this garden hole digger onto your power drill to dig faster and easier-and neater-than a shovel or trowel. The Made in the USA, powder-coated steel bit has angled blades that create a perfectly round, flat-bottomed hole to fit standard 4 inch or 6 inch potted plants. The drill bit compresses soil into the sides and bottom of the hole, so there’s no mound of dirt left over.
