User Feedback
Being in the HDD industry for over 14 years, I have been able to drill with a variety of different tooling in a wide range of soil conditions. Currently, we are running 14 rigs ranging in various sizes. In 2021, the majority of our rigs were drilling in very poor ground conditions, so I was on a mission to find a higher quality bit. Kondex sent us two cobble bits and we were able to test them in some of the poorest ground conditions. The Kondex bit performed exceptionally well in rock/cobble, and we were able to get more production and three times the life versus other comparable brands. In my opinion, the Kondex cobble bit is the best on the market.
[The bit’s] performance outmatches competitive bits. [It delivers] more aggressive steering [and] better longevity in tough rock conditions. [I was] surprised at how well it held up and its longevity in tough conditions. Looks like you’ve got yourself a superior product.
This tip is awesome! Going through rock and I don’t even have to idle up. Just wiggle it and it goes right through! Even after using for some time, the Kondex bit is still better than a new bit of what we were normally running. Switching to the Kondex cobble bit from now on!
The Kondex bit we are running on our 24x40 drill has held up and outperformed the competition. From clay to solid rock, we have noticed longer life, better steering capabilities, and all around better performance in all categories with minimal wear. Ten times more footage per bit compared to competition.
