material and durability: 2 inch Torx (star) screwdriver bits are made from quality S2 alloy steel. S2 steel delivers toughness and impact resistance for repeated use in hand and power tools. Magnetic, extralong design: Each bit has a magnetic head and a 2 inch length to hold fasteners securely and reach screws located in deep or tight spaces. Complete size range: 12piece set includes T5, T6, T7, T8, T9, T10, T15, T20, T25, T27, T30, and T40 so you have the common Torx/security sizes needed for most jobs. Wide compatibility: Works with electric screwdrivers, hand screwdrivers, electric drills, and air drills. The magnetic tips make bit retention simple when used with bit holders or chucks. Reliable performance: S2 alloy construction resists wear and impact, reducing camout and extending bit life under normal professional and DIY use. Practical use scenarios: Electronics and small appliances: Use the T5–T10 bits for laptops, game consoles, smartphones, and other electronics that use security Torx fasteners. Appliance and furniture : The longer 2' bits reach recessed screws in household appliances, fixtures, and assembled furniture where a standard bit is too short. Automotive and mechanical work: Use the larger sizes (T20–T40) for automotive trim, brake components, and other mechanical fittings that require durable, secure Torx drivers.
