RUKO High Speed Steel (HSS) Twist Drill Bit - 4mm x 75mm

Designed for precision and durability, the RUKO High Speed Steel (HSS) Twist Drill Bit is a fully ground, professional-grade tool manufactured to DIN 338 Type N standard. It is crafted from robust, heavy-duty high speed steel, ensuring excellent performance and long service life even under demanding conditions.
