- Material: High speed steel 9341 (HSS 9341). Suitable for drilling various metals including stainless steel, iron, copper, aluminum alloys, and other metals with medium to low hardness. Durable and reliable in use; performance is better than HSS 4241/4341. - General purpose: Provides a balanced combination of hardness and toughness for wear resistance in common drilling tasks. - Reduced shank: Extends the size range of a portable drill chuck. Features a common flute and overall length for minimal adjustment when changing tools. - Wide application: Designed for drilling in low to medium tensile strength materials such as aluminum, iron, copper, brass and metal. - Use scenario: Drilling aluminum brackets or enclosures for electronics, bicycles, or other projects where lightweight metal parts are required. - Use scenario: Fabricating iron or steel components in DIY or workshop settings, such as brackets, plates, or mounting holes. - Use scenario: Working with copper, brass, or stainless steel fittings for hardware assemblies, plumbing joints, or decorative metalwork.
