BOART LONGYEAR® began manufacturing DeltaTools™ overburden drilling products in 1989 at its Burghaun facility in Germany to serve the foundation construction market in Europe. BOART LONGYEAR® overburden tools were quickly recognized by the industry as reliable and well-designed.
From the start, our customers appreciated our use of high-quality steels, precise heat treating and thread gauging as well as the development of new tungsten carbides for the drill bit line. Our attention to detail has made the DeltaTools product line one of the most respected names in the industry.
