GREAT TOOLONLY USED ONCE AND GLAD TO HAVE IN MY FOOL BOX.PRICE GOOIDONLY COMMENT JUST A HAIR LARGE BIT WOULD BE GREAT

Fonctionne super bien pour installer des piquets pour la neige l’hiver!

Worked great in our Jersey Shale. I was able to move over a little and create a hole instead of hammering and breaking the driveway marker. Note: the flutes of the drill bit are only about seven inches long. It was still enough to go all the way in up to my hammer drill chuck. On this damp December day I was able to set the markers with a tap from the bottom of the drill. No hammer needed.

I bought this as it is that time of year to put out our driveway and turn-around markers. It's been below freezing here so the sooner I get them in the better. It arrived yesterday and today, loaded with some new and some old markers I set about drilling the holes deep enough (now) they won't come loose. An earlier review lamented the bit won't penetrate rock. Um, the flat tip suggested as much. This didn't cause an issue as moving a 1/2" away solved the problem. In most cases I went down 6" in others, with longer fiberglass rod I went down the length of the bit. Easy-Piesy. I really liked the holes drilled were precisely the correct diameter so the markers stayed upright with zero lateral play. It was an outstanding investment If I reposition or in future years wait until after the ground is frozen solid for several inches ... zero problem. I returned the bit to it's plastic case for use in 12 months. I'm thrilled some clever guy somewhere came up with the idea and the proper width, length, and strength. I was also skeptical of a drill bit drilling through earth, as earth is not oak, pine, or maple. It did a remarkable job!

Works nice!
