About

After years in the field seeing first-hand the successes and failures of other tool designs, our founder, Riff Wright, knew he could do better. So he set off with partner David Bullock to do just that. They founded Radius HDD and began working directly with contractors to address the problems drillers were having with their existing tools. In no time, Radius was building the best rock tools in the business.

More than a decade later, Radius still delivers the best — now in rock tools and much, much more. In fact, Radius offers a complete line of the highest quality tools to HDD professionals worldwide through the most comprehensive catalog and website in the industry. The secret to our success? Unbeatable value. You see, we’ve never stopped working with drillers in the field. You know what works and what doesn’t. And we’re smart enough to listen. After all, our job is to make your job easier.
