Not really needed but it was nice to minimize bending.

I was very excited to give this to my husband who has had two knee replacements. Unfortunately, the extender didn't fit either of the two drills that we own. We went out and bought a decent $150.00 drill to be sure that it would have enough power to dig the hole. After that, the bit did not work that well. Great idea, but . . .More > < Less

Easy Digging

The idea to create a garden hole digger came to Maker Michele Morton when she was helping folks in her community plant their gardens. She made The MAXBIT drill attachment to do the digging job quickly, easily, and more neatly.

The patented curved angles of the bit compress dirt into the bottom and sides of the hole, resulting in a perfectly round, flat-bottomed hole each time. This compressing action eliminates the pile of dug-out dirt for you to deal with when you’re done. The bit and its extension piece fit on most common power drills, and are made in West Point, Mississippi with ultra-tough steel that’s powder coated to prevent rust.

The MAXBIT works in tilled or untilled soil, and makes holes to fit standard 4” or 6” potted plants. With the power of a drill doing the digging, planting a garden is easier—and faster—than ever.
