4-Piece Screwdriver Bit Extension Rod Set

This set includes four screwdriver bit extension rods with hex drive ends for a secure connection to power drills or manual drivers. The rods come in lengths of 60 mm, 100 mm, 150 mm, and 300 mm. They feature black shafts, silver metal collars, and red knurled end housings that serve as bit holders for quick bit changes. The straight cylindrical design allows access to tight confined areas, and the 300 mm rod is useful for deep engine compartments.
