The IRONCUBE 9-piece insulated screwdriver system includes eight replaceable magnetic screwdriver bits and one insulated handle. A separate 125-250V AC voltage tester is also included as an additional accessory and is not counted as part of the 9-piece screwdriver system. The eight 110 mm bits include Phillips PH0, PH1 and PH2, plus slotted 2.5 mm, 3 mm, 4 mm, 5.5 mm and 6.5 mm sizes. The insulated screwdriver system is covered by VDE certificate No. 40059333 and is designed for electrical work up to 1000V AC. The separate single-pole phase tester is covered by VDE certificate No. 40017622 and is rated for 125-250V AC. The interchangeable design allows one handle to cover common electrical installation and maintenance tasks. Magnetic tips help hold compatible screws, and the transparent case keeps every component organized. Always de-energize circuits when possible and follow proper electrical safety procedures.
