1. S2 steel is used as the bit material, which has good wear resistance and heat resistance 2. On the basis of S2 steel, alloy elements such as chromium, molybdenum, tungsten, and vanadium are added to improve hardenability, toughness, wear resistance, and heat resistance 3. With magnetic bit, magnetic adsorption 4. Anti-slip handle can increase the friction between the hand and the screwdriver, making work easier 5. The bearing reduces noise and is smooth 6. The bit is precisely matched, not easy to damage the screws, and easy to disassemble 7. Bit specifications: cross 1.2, triangle 0.6, pentagon 0.8, hexagon T2, middle plate 2.5 8. Size: about 13.4 x 1.6cm 9. Weight: about 116g
