High-quality tools are crucial to process metals. The exact connection of components requires an accurately produced hole. Unsmooth or incorrectly produced hole with burrs may cause reworking and the quality is crucially impaired. As a consequence, it is paramount to use drill bits produced in compliance with the applicable DIN standards. Heller uses selected HSS steels for its metal drill bits. At the same time, we focus on high-quality workmanship, evident for instance in the precision grind of the tip and helix as well as the low run-out values. Heller always focuses on the demands of professional users. After all, all Heller products contribute to faster and more cost effective working for traders.
