Works good for me

The bit worked as described.

Tool worked great for getting 6 inch sdr pipe 20 feet under a driveway. Only downside I had to weld on each fin a piece of metal so the bit was slightly bigger then the pipes bell.

The bit is solid and effective. It is, however, quite heavy so if you strike a rock or obstacle and the bit works its way around the weight of the bit cause the pipe extensions to vibrate resulting in a larger bore diameter. That being said, the bit is well made and very durable.

I purchased the full Borit kit and the six inch bit to cut an under ground chase for electrical connections for my generator install. It was an eight foot bore and went very well. I don't know how I could have done it otherwise. Saved a bunch of money doing it myself. It is a bit messy and you do have to dig trenches on both sides. but it did the job nicely and I have moved on to the next phase of the project. Thank you Borit for a great tool.

I bored in a 4-inch line for a downspout drain 14+ feet under my patio. Followed instructions and took my time and everything went smooth. I did deviate a little by using a ½: DeWalt battery operated Impact (3 different speeds) with a coupling to fit the tool which is available off the shelf. I'm very happy having bought the kit. There have been quite a few times over the years where I could have use this and I should have bought this earlier. Coincidentally, I have a friend at work that needs to run wire under a new sidewalk for landscape lighting - it's going to save him a headache. Thanks!
