Long HSS DIN1869 3.5 x 210mm gold metal twist drill bit

A high-quality metal drill bit that meets the expectations of both DIY enthusiasts and professionals. Made from high-speed steel (HSS), it offers not only excellent durability but also high drilling precision. Thanks to its extended design, it allows work in areas inaccessible to standard drill bits and enables the drilling of unusually deep holes.

With a specially ground 130° tip, the bit effectively centers itself on the surface, minimizing the risk of slipping when starting the drilling process. This feature is particularly important when working with harder materials such as structural steel, non-ferrous metals, cast iron, or plastics.

Additionally, the drill bit’s golden color not only gives it an aesthetic appearance but also indicates increased wear resistance and reduced friction during drilling, resulting in longer tool life.
