13-piece bit mix: Includes PH1, PH2, PH3, SQ1, SQ2, SQ3, T20, T25, and SL8 bits, with two each of PH2, SQ2, T20, and T25. S2 alloy steel body: The bits use S2 alloy steel with 56-60HRC hardness, impact and wear resistance, and a black phosphate coating that resists corrosion. CNC-machined tips: Precision machining helps provide accurate tips, while the torsion zone spreads concentrated force and alleviates excessive loading at the bit tip. Strengthened magnetic hold: The magnetic feature helps pick up screws, and the magnetism does not decay after multiple uses. 1/4-inch drive format: The set works with manual screwdrivers, electric screwdrivers, electric drills, and other tools. Mechanical maintenance range: Suitable for mechanical maintenance, home assembly, furniture repairs, automobiles, motorcycles, bicycles, woodworking, and electronic equipment.
