The 131‑842 counterbore is engineered for precision machining of M5 threaded fasteners, with an overall length of 80 mm, a 10 mm cutter diameter, and an 8 mm plain shank. Made from high‑speed steel (HSS), this tool is designed to produce flush or below‑surface seating of cap screws in metal workpieces, providing clean finishes and consistent results in industrial fabrication and maintenance settings.
This counterbore drill bit simplifies the process of creating flat‑bottom cavities for M5 fasteners, allowing fastener heads to sit flush or slightly below the surface. Paired with proper speeds and feeds, it helps maintain part integrity and maintains alignment in tool‑holding setups.
