138-in-1 Screwdriver Set CRV Bits for Mobile Phone Repair

This 138-in-1 professional precision repair tool kit is designed for electronics repair businesses, service centers, distributors, and bulk buyers who need a reliable, all-in-one solution for daily maintenance, diagnostics, and disassembly work. With 117 Cr-V precision bits and 21 auxiliary repair tools, this set supports high-efficiency repair operations across a wide range of electronic devices.

The kit is engineered for PC maintenance and assembly, including RAM upgrades, SSD replacement, motherboard installation, and general computer servicing. It is also suitable for game console repair (PS4, Xbox, etc.), drones, smartphones, tablets, and other consumer electronics where precision and tool variety are essential. Rare and specialty bit types are included to support servicing of diverse and branded devices.

To improve workflow efficiency, the screwdriver handle is ergonomically designed with a non-slip grip for stable control during long repair sessions. The 4.56-inch alloy steel extension shaft provides strong rigidity for deep screw access, while the flexible extension shaft (up to 180°) enables technicians to reach tight or angled spaces inside compact device structures, significantly reducing disassembly time.

The kit features a dual magnetic system to enhance repair organization and accuracy. The magnetizer/demagnetizer strengthens bit magnetism for secure screw handling, while the magnetic mat keeps removed screws and small parts sorted during teardown and reassembly—minimizing loss and errors in professional environments.

All precision bits are made from heat-treated Cr-V steel (50-56 HRC) for high hardness, wear resistance, and long-term durability. Common sizes are included with spares, ensuring uninterrupted work and extending the service life of the set in high-frequency repair scenarios.

All components are clearly labeled and neatly organized in a compact storage case for fast access, easy inventory management, and convenient transport between workstations or job sites.
