Standard hex shank adapters typically work with power tool bits at higher torque, whereas this adapter is optimized for precise, low-torque applications.</p> <h4>Q: Is this adapter suitable for use with a power drill or electric screwdriver?</h4> <p>A: This adapter is designed for precision hand tools and low-torque screwdrivers rather than high-torque power drills. It is best suited for delicate work such as electronics assembly, watch repair, or other fine detail tasks where controlled, gentle fastening is required.</p> <h4>Q: How does the magnetic feature help during use?</h4> <p>A: The built-in magnet securely holds your 4mm
