High durability and consistent results for metal and aluminum sheet work Key benefits Long-lasting cutting performance: Made from 4241 high-speed steel with a nitriding surface treatment for increased hardness and improved wear resistance. Built to withstand repeated use on metal and aluminum. Clean, precise holes: Engineered for accurate drilling and hole enlargement in metal and aluminum sheets up to 2 mm thick, delivering smooth, burr-reduced finishes. Broad compatibility: Works with hand-held electric drills, drill presses (bench drills), and other standard drilling equipment for flexible use in workshops, home projects, and professional settings. Cost-effective solution: Single-step design covers multiple hole sizes, reducing the need for many different bits and lowering long-term tool costs. How it solves common problems Eliminates frequent bit replacements by resisting wear and edge dulling on hard sheet materials. Reduces the need for secondary deburring and filing by producing cleaner holes on first pass. Lets you use one reliable tool across a range of projects and drill types, simplifying tool selection. Applications (practical use scenarios) Home improvement: Install metal or aluminum fixtures, hinges, or fasteners on cabinets and panels without switching bits. Electrical and HVAC work: Punch and enlarge clean access holes in thin metal enclosures, junction boxes, and duct panels up to 2 mm. Light automotive and sheet-metal tasks: Drill or widen holes in body panels or trim pieces made from thin aluminum or steel sheets. Technical highlights Material: 4241 high-speed steel (HSS) Surface treatment: Nitride (nitriding) for enhanced hardness and durability Intended use: Drilling and hole enlargement in metal and aluminum sheets up to 2 mm thickness Compatibility: Electric drills, bench drills, and similar drilling machines Design: Single-step drill covering multiple hole sizes for a durable, versatile solution Use this bit when you need reliable, accurate holes in thin metal or aluminum sheets with fewer tool changes and consistent results.
