Tracing its roots to Jakob Heller's first workshop for drilling tools in 1583, Heller is part of the Serafin group and a world leader in premium drilling and cutting tools. In 1928 Heller became the first company to manufacture tungsten carbide bits in serial production and has built upon this technology with industry-leading 2- and 4- and tri-cutter hammer drill bits. Heller also produces drill bits for other materials as well, including wood, all types of metal, and other specialty bits such as countersink, Forstner, and universal bits for ceramic, tile, masonry, and concrete. With production centered at its state-of-the-art facility in Dinklage, Germany, Heller has expanded to manufacture other related products such as chisels, saw blades, and multitool cutters.
