Twist drill bit set ECO HSS-Co 5% – resilient tool for hard metals

The twist drill bit set ECO HSS-Co 5% offers cobalt-alloyed drill bits for demanding metalwork and high thermal loads. The ground model according to DIN 338 supports precise drilling and reliable processing of hard materials.

The twist drill bits consist of HSS-Co with a cobalt content of 5%. As a result, the tool remains resilient and retains its cutting edge even at higher working temperatures. This is particularly advantageous when processing tough metals, where conventional drill bits can wear out more quickly. The short design ensures high stability during the drilling process and reduces unwanted vibrations.

From a diameter of 3 mm, the drill bits have a 135° split point. This facilitates precise positioning and reduces wandering of the drill tip on smooth metal surfaces. The graduation in steps of 0.5 mm enables a differentiated selection of the suitable diameter for numerous applications.

The straight shank ensures secure holding in common drill chucks. The tool can be used in both mechanical and non-mechanical hand tools as well as in machine tools. This makes the set suitable for workshops, production areas, assembly applications and industrial maintenance.

The sturdy metal case protects the twist drill bits during transport and ensures organized, ready-to-hand storage. The set is designed for precise drilling work in hard metals as well as for applications with increased heat generation.
