Draper Expert HSS Cobalt Drill Bit 12mm Pack of 1
The 12mm Draper Expert HSS Cobalt Drill Bit is engineered for larger-diameter drilling tasks across heavy fabrication, structural metalwork, and mechanical engineering applications. This substantial diameter size is commonly used for bolt holes in structural steel, heavy machinery assembly, and industrial installations where robust fastening points are essential. The 230mm overall length provides the reach necessary for drilling through thick materials whilst maintaining sufficient rigidity to prevent wandering and ensure accurate hole positioning. The high-speed steel construction enhanced with 5% cobalt content delivers outstanding performance in materials that would quickly destroy conventional HSS bits. This cobalt addition significantly improves both hardness and heat resistance, allowing the bit to maintain its cutting edge when drilling stainless steel, cast iron, and hardened alloys. The result is extended service life, reduced downtime for tool changes, and consistently clean holes throughout demanding drilling operations, making it an economical choice for professional applications. Features and Benefits: • 12mm diameter suitable for heavy-duty structural applications • 230mm length provides reach for thick material drilling • 5% cobalt addition ensures exceptional wear resistance • Superior heat tolerance maintains cutting performance • Reliable performance in materials that challenge standard bits Contents: • 1 x HSS Cobalt Drill Bit, 12 x 230mm
