- Material: HSS 9341 high speed steel. Suitable for drilling metals with medium to low hardness, including stainless steel, iron, copper, aluminum alloys and brass. Delivers medium to high durability and performance, outperforming HSS 4241/4341. - General purpose: Hardness and toughness balanced for wear resistance, making it suitable for most general drilling tasks. - Reduced shank design: Extends the size range of portable drill chucks. Uses a common flute and overall length for minimal tool change adjustments. - Wide application: Designed for drilling low to medium tensile strength materials such as aluminum, iron, copper, brass and metal. - Use scenarios: - Drilling aluminum components for fabrication or repair work. - General metal drilling in DIY projects or workshop environments, including copper and brass parts. - Light to moderate drilling of stainless steel, iron and other metals where medium hardness is encountered, with easy tool changes thanks to the reduced shank.
