Longlasting durability: With a hardness of up to 62HRC, the Electric Drill Screwdriver Bit Set is optimized for precision and built to withstand tough drilling tasks. Crafted from hardness material, these bits offer a longer service life and durability for all your drilling needs. Efficient torque control: Featuring powerful torque transmission and a mechanical design that partially absorbs the drill's reaction force, these bits provide smooth torque control as the screw head touches, helping to improve project results. Antislip design: Nonslip teeth reduce screw slippage, improve bite, and provide wearresistance, contributing to better work quality and higher workmanship standards. Portable convenience: The compact design makes storage easy in tight spaces, and the magnetic feature helps keep track of bits during use, ensuring convenience and organization. Use scenario: Building or assembling furniture or cabinets at home, where precise screw driving and clean finishes are important. Use scenario: Quick repairs or installations in wood, plastic, or light metal where controlled torque and reduced slippage improve accuracy and efficiency. Use scenario: Electronics or delicate hardware assembly that benefits from secure bit retention and reliable torque control.
