Micro precision-drills made of solid carbide for the production of holes between 0.5 mm and 3.0 mm with hole depths 3xD to 12xD. Available with both external shank cooling via six cooling channels and internal shank cooling via two twisted cooling channels. The standard drill tolerance of m7 enables the production of holes with a hole quality of H9 under normal conditions.
Thanks to the optimal interaction of finest carbide and a coating selection optimally adapted to the ISO material groups, the micro-precision drills from Kaestner-Tools offer highest performance, longevity and process reliability under almost any condition.
