Magnetic precision bits: 40-piece assortment with high-strength chrome-vanadium inserts enables gentle opening of smartphones, tablets, and notebooks without tool loss thanks to intelligent magnet technology. Optimal tight-space use: specially developed 180-degree rotating mechanism with bidirectional support minimizes physical strain while delivering optimized performance in compact workspaces. Stable ratchet construction: precise four-locking technology in a 45-tooth design reduces slip and ensures long-term reliability. Durable quality: hardened alloy steel construction with rust-resistant properties provides lasting performance. Strong magnet holds screws securely, and the non-slip grip enables precise work, reliable under heavy use. Applications and use scenarios: - Electronics repair: opening and servicing smartphones, tablets, and notebooks without damaging components. - Tight-space assembly and maintenance: work in confined chassis areas, cameras, small appliances, or laptop interiors. - Field service and upgrades: on-site screw driving in limited spaces with stable control and repeatable accuracy.
