Material: HSS high-speed steel for durability and reliable cutting performance in metalworking. Color: gold for easy identification in your toolkit. Length: approximately 80 mm for reach in tight or deep holes. Shank diameter: approximately 9 mm to fit standard chucks and holders. Key benefits: - Durable HSS construction resists wear and heat during drilling - Gold color helps you quickly locate and select the bit - 80 mm length provides reach for deeper holes - 9 mm shank fits common drills and chucks for broad compatibility Use scenarios: - Drilling holes in metal workpieces in a workshop or maintenance setting with a standard 9 mm chuck - Creating deeper holes in metal plates or blocks where shorter bits cannot reach - General purpose drilling in hard plastics or non-ferrous metals where a robust HSS bit is suitable
