Set de 25 brocas helicoidales RUKO SPB DIN 338 HSS TiN acero azul

For machinists and metalworkers who need a complete set of twist drill bits in a durable steel case, the RUKO SPB Set 25-Piece provides precision drilling in steel, cast iron, non-ferrous metals, plastics, and wood. Each bit is made from high-speed steel (HSS) with a titanium nitride (TiN) coating for increased tool life, improved heat resistance, and improved wear resistance. The bits are ground from solid, have a 118° point angle, conical ground point, right-hand cutting direction, and h8 tolerance. Sizes range from 1.0 mm to 13.0 mm in 0.5 mm increments, covering a wide range of drilling tasks. The set comes in a steel sheet case for organization and protection.
