- Material and coating: Made of high-speed steel (HSS) with a titanium coating for wear resistance and durability. Designed to provide long service life with improved wear and fusion resistance. - H2 tolerance: Precise threading with reduced risk of overcutting, suitable for beginners and professionals alike. Works for drilling and tapping stainless steel (below 30 HRC), as well as aluminum, die steel, ordinary steel, non-ferrous metals, and hard plastics. - Spiral tip design: Spiral tip enables efficient chip removal, minimizes chip accumulation, and promotes smooth threading. - Versatile through-hole tapping: Suitable for through hole threads and usable in aluminum, steel, and plastic, making it a reliable tool for a wide range of DIY and professional projects. Use scenarios: - Tapping threaded holes in an aluminum electronics enclosure or chassis for secure fastener installation. - Drilling and tapping stainless steel components (below 30 HRC) in machinery or automotive assemblies. - Prototyping or repairing plastic parts or die-cast components that require precise threaded holes for fasteners.
