Metal Drill Bit, Ruwag, 3.5mm (4 pack) BY WOODLY

The Ruwag 3.5 mm metal drill bit is a precision twist bit designed for drilling through various metal materials — such as mild steel, aluminum, brass, and other medium‑gauge metal alloys. The bit is made from high‑speed steel (HSS), giving it sufficient hardness and cutting strength for clean, accurate holes when used with appropriate drilling speed and, when needed, lubrication. The spiral-flute design allows efficient evacuation of metal chips and reduces heat buildup, which helps maintain bit sharpness and prolong service life.
