Metal Drill Bit, Ruwag, 4mm (4 pack) BY WOODLY

The Ruwag 4 mm metal drill bit is a standard high‑speed steel (HSS) twist bit designed for drilling neat, accurate holes in metal materials — including mild steel, aluminium, brass and other light‑to‑medium gauge metal alloys. It is suitable for general‑purpose metalwork: creating holes for bolts, screws, rivets or fasteners in metal plates, brackets, frames, enclosures — useful for fabrication, maintenance, repair, metal assemblies, and DIY metalwork. The bit’s flute (spiral grooves) helps evacuate metal chips efficiently and reduces heat accumulation while drilling, which improves cutting performance and extends bit life.
