10Pcs PH3 Phillips Impact Screwdriver Bit 1/4" Hex Shank 4" Long Magnetic

The impact screwdriver bits are made of specially heat-treated S2 steel, which offers high strength and hardness (HRC60-61). They are durable, anti-bending, and feature a black phosphate finish for enhanced corrosion resistance, adhesion, and surface hardness. The head of the screwdriver is magnetized for easy use. Phillips bits designed with magnetism can stably absorb the screws vertically or tilted and easily fix the screws, especially in a small space, which can make it more convenient to complete the work. Precision CNC machined cross head, precise appearance, reduces head wear during high-intensity tightening operations. Special torque buffer design, when the vibration generated during operation is absorbed by this part, the torque transmission is increased, achieving the effect of protecting the screwdriver head and extending the service life. Phillips head drill bits are specifically designed for driving screws into wood, metal, and other materials effortlessly. Can accurately tighten screws without damaging screws and screwdriver bits. 1/4" hex shank driver bits can be used with electric screwdrivers, manual screwdrivers, electric drills, etc. for electricians, mechanical repair work, and furniture installation. Before operation, make sure the screwdriver bit is firmly inserted into the power tool chuck. Avoid excessive force when tightening the screw to prevent the bit from being damaged or slipping out. Adjust power tool speed and torque settings according to the material being processed.
