A good quality screwdriver set for professional use should include a wide range of driver types and sizes to handle a variety of tasks, feature durable construction with heat-treated steel blades and corrosion-resistant materials, and have comfortable, non-slip handles that provide excellent grip and control.
Some recommended professional-grade screwdriver sets include the Craftsman 9-31794, Klein Tools 85074, and GearWrench 20-Piece Screwdriver Set.
