Prevents Slipping: Our electric drill bits feature nonslip teeth with antislip and wearresistant properties, reducing screw slippage. Designed for use with most electric drills and screwdrivers, this improves work efficiency and increases precision for consistently accurate results. Wear Resistant: Constructed from quality materials, the Electric Drill Screwdriver Bit Set offers a hardness of up to 62HRC, making it suitable for tough drilling tasks. The longer service life delivers reliable performance and precision over extended use. Efficient Torque Control: A mechanical principle design absorbs the drill's reaction force when the screw head is touched, effectively preventing breakage and ensuring powerful torque transmission for dependable project outcomes. Improves Efficiency: Crafted with precision, the bits feature a metal shock damping system that reduces cracking when penetrating sheet metal with dovetailed nails. Antishock technology further enhances efficiency for a smooth and easy drilling experience. Use scenarios Furniture and cabinet assembly: driving screws into wood with greater control and precision to ensure tight, professional results. Automotive or appliance : fastening or removing screws in sheet metal panels with reliable torque and reduced risk of bit breakage. Metal shelving installation and light fabrication: drilling into metal sheets and components with improved efficiency and reduced cracking.
