Century:Black Oxide S and D Drill Bits

Precision-engineered black oxide drill bits designed for general-purpose and heavy-duty drilling applications. The black oxide coating provides superior corrosion resistance and extended tool life compared to standard steel bits. Ideal for drilling into steel, aluminum, wood, and plastic materials. Available in both split-point (S) and standard (D) configurations to match your specific project requirements. These durable bits deliver consistent performance across multiple drilling operations while maintaining sharp cutting edges longer.
