Each bit is equipped with a powerful magnet at its end, allowing you to easily grip and screw in screws without slipping or damaging them. This feature ensures a secure grip, improving work efficiency and accuracy. The bits feature a non-slip, serrated design, which allows for more efficient screw tightening and reduces the risk of the screwdriver slipping off the screw head. This design is particularly useful for applications with high torque. Made from high-quality D1 alloy steel, these bits are designed to withstand the rigors of screwdriving. Their impact resistance makes them suitable for heavy-duty tasks in construction, woodworking, and metalworking. With their 1/4-inch hex shank, these bits are compatible with a wide range of drills and power tools, making them a versatile tool for your professional projects. The set includes bits in various sizes, such as 25 mm, 50 mm, 65 mm, 70 mm, 90 mm, and 150 mm, to ensure you get the right choice.
