Precision-ground HSS twist drill bit with TiN coating, 1/2 inch diameter, DIN 338 standard, for reliable drilling in steel, cast iron, non-ferrous metals and plastics.

Overview

The RUKO SPB-DIN338-HSS-TiN is a high-performance twist drill bit made from high-speed steel (HSS) with a titanium nitride (TiN) coating. It conforms to DIN 338, ensuring standardised dimensions and geometry for general-purpose drilling. The 1/2 inch (12.7 mm) diameter bit features a cylindrical straight shank, a 118° point angle, and right-hand cutting flutes. The TiN coating increases surface hardness to approximately 2300 HV and withstands working temperatures up to 600 °C, reducing wear and extending tool life.
