Precision screwdriver set with 117 double-sided magnetic CRV bits, 55-60 HRC chrome vanadium alloy for laptop, phone, and electronics repair toolkit, includes flexible extension shaft up to 60mm for hard-to-reach screws in a black, blue, or red box.
117-in-1 Precision Screwdriver Set with Magnetic CRV Bits and Flexible Shaft for Electronics Repair

Repairing modern electronics like laptops, smartphones, and tablets requires the right tools for the job, specifically designed for their small, delicate fasteners. This comprehensive 117-piece toolkit provides a professional-grade solution for hobbyists and technicians alike. The core of the set is its array of 117 double-sided magnetic bits crafted from chrome vanadium steel alloy (CRV), offering a reliable hardness of 55-60 HRC for effective torque transfer without stripping screw heads. Combined with a unique flexible extension shaft that extends up to 60mm, this kit is engineered to tackle repairs in tight, three-dimensional spaces where standard tools cannot reach, making it a practical choice for maintaining a wide range of consumer electronics.
Features and Construction

This toolkit is built around functionality and durability for non-precision maintenance tasks. Every component is selected to address the common challenges of electronics repair, from secure bit engagement to accessing confined areas.
Material and Build
The screwdriver bits are manufactured from chrome vanadium steel alloy, commonly referred to as CRV. This material is known in toolmaking for its balance of toughness and impact resistance, which helps prevent the bits from chipping or deforming under pressure. The specified hardness rating of 55-60 on the Rockwell C scale (HRC) indicates a level of rigidity suitable for the screws found in consumer electronics, providing a firm grip without being overly brittle. Each bit is double-sided and magnetised, a feature that securely holds screws to the tip during installation or removal, significantly reducing the frustration of dropping and losing tiny components inside a device.
Size and Practical Fit
The kit's standout feature for accessibility is its flexible shaft extension rod. This accessory can be adjusted to provide up to 60mm of additional reach, but its key advantage is its flexible, soft shaft. This allows the bit to bend and navigate around internal obstructions, such as cables or circuit boards, to reach screws that are not in a direct line of sight. This is particularly valuable for three-dimensional work inside devices like laptops or game consoles. The entire set, including the 117 bits and extension, is housed in a lightweight, compact case, making it portable and organised for both professional workshops and home use.
Uses and Placement

The toolkit's design directly targets the fastening systems used in contemporary portable devices and delicate mechanisms. Its application scope is clearly defined for common repair and maintenance scenarios.
Event or Professional Use
For professional repair technicians or IT support staff, this set offers a consolidated solution for on-site or workshop repairs. The extensive selection of 117 bits covers a vast majority of screw types found in brands like Apple, Samsung, Dell, and Sony. The magnetic function increases efficiency, allowing for quicker screw handling during repetitive disassembly tasks. The flexible shaft is indispensable for professional work on devices with complex internal layouts, such as all-in-one PCs or digital cameras, where screw placement can be deeply recessed or angled.
Everyday Home Use
For the home user or DIY enthusiast, this kit demystifies basic electronics repair. It is explicitly suitable for maintaining and repairing laptops, tablets, smartphones, watches, and eyeglasses. The compact design means it doesn't require much storage space, and the organised case keeps bits from being lost. Whether replacing a smartphone battery, tightening loose glasses hinges, or cleaning a game console, having the correct bit immediately to hand can turn a potentially frustrating job into a straightforward one, potentially saving on costly professional repair fees for simple issues.
Benefits and Buying Value

Investing in a dedicated precision toolkit brings tangible advantages over improvising with ill-fitting tools. The value here lies in its specialised design, completeness, and the practical problems it solves for the user.
Reuse and Low Maintenance
The use of CRV steel contributes to the kit's longevity. This material's resistance to wear means the bits should maintain their shape and driving edges through repeated use on soft metal electronics screws. The magnetic property is a permanent feature of the bit material, not a coating that can wear off. The storage case protects the bits from corrosion and physical damage when not in use. As a complete set, it eliminates the need to purchase individual screwdrivers for different devices, representing a one-time investment for a wide range of future repair jobs.
Why Choose This Product
This set distinguishes itself through its specific combination of high bit count, magnetic functionality, and the unique flexible extension. Where many basic sets offer only a standard ratchet and short bits, this kit includes the flexible shaft specifically for three-dimensional access—a recognised pain point in electronics repair. The 55-60 HRC hardness provides a technical specification that assures effectiveness, while the choice of three case colours (black, blue, or red) offers a small degree of personalisation. It is a functionally focused toolkit designed for the practical demands of modern device maintenance, without unnecessary extras.
