#2 Anti Slip Phillips Impact Screwdriver Bit PH2 1/4" Hex Shank 3.5" (90mm) Magnetic Cross Head Drill Bits Chrome Plated S2 Steel Screw Driver Power Electric Tools, Silver/Black

The impact screwdriver bits are made of specially heat-treated S2 steel, offering high strength and hardness (HRC58-60). They feature a bend-resistant design and a chrome plated surface treatment that significantly enhances corrosion resistance, adhesion, and surface hardness The head of the screwdriver is magnetized for easy use. Hex 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.  Anti-slip screwdriver bits have high-density gripping teeth to lock onto screw heads, preventing slippage under high torque. The torque-optimized design absorbs shock and disperses rotational stress, reducing tip breakage in high-strength applications (e.g., automotive repairs, industrial assembly). Phillips head drill bits are specifically designed
