117 in 1 Screwdriver Bit Set with Double-Sided Magnetic CRV Bits, Hardness 55-60 HRC, Chrome Vanadium Steel Tool Set for Laptop, Mobile Device, Watch and Glasses Repair with Flexible 60 mm Extension Rod
117 in 1 Magnetic CRV Screwdriver Bit Set with 55-60 HRC Hardness and Flexible Extension for Device Repair

This comprehensive 118-piece tool set is engineered for maintaining a wide array of modern electronics, from laptops and smartphones to delicate items like watches and glasses. Its core strength lies in the 117 double-sided screwdriver bits, fabricated from chrome vanadium steel (CRV) with a specified hardness of 55-60 HRC. This material choice contributes to a sturdy, impact-resistant build suitable for the task. The magnetic property of each bit is a practical feature, designed to hold screws securely during the tightening process, which can improve performance and save time during repairs. The set's compact and lightweight nature makes it highly manageable for intricate work, while the inclusion of a flexible shaft extension rod, adjustable to 60 mm, addresses the common challenge of accessing screws in confined or awkward three-dimensional spaces.
Features and Construction

The set's construction is defined by measurable specifications and material choices geared towards practical repair work on consumer electronics.
Material and Build
The screwdriver bits are manufactured from chrome vanadium steel (CRV), a material noted in the source for its sturdiness and impact resistance. A key technical specification provided is the hardness rating of 55-60 HRC (Rockwell Hardness Scale), which indicates a level of durability suited to non-precision maintenance tasks. Each bit is double-sided and magnetised, a design feature that aids in holding screws during assembly or disassembly, potentially reducing frustration and improving efficiency.
Size and Practical Fit
The set is described as lightweight and compact, a practical advantage for handling during detailed repairs on small devices. A significant functional component is the flexible shaft extension rod, which can be adjusted to a length of 60 mm. This flexibility allows the user to navigate around obstacles and access screws that are not in a direct line of sight, making it highly suitable for three-dimensional work inside electronic casings or other assembled items.
Uses and Placement

The product is clearly designated for maintenance and repair work on a specified range of electronic and delicate items.
Event or Professional Use
While ideal for professional technicians or IT support roles dealing with frequent hardware repairs, the set's scope is explicitly defined as 'non-precision maintenance'. This indicates its suitability for common repair and assembly tasks on consumer goods rather than highly calibrated industrial equipment. Its application range includes repairing laptops, mobile devices, tablets, PCs, smartphones, game console controllers (PS4/Xbox), and their associated cameras.
Everyday Home Use
For the home user, this set provides a concentrated toolkit for common electronic upkeep. It is specifically mentioned as being very suitable for repairing delicate personal items such as watches and glasses, in addition to standard consumer electronics. The magnetic bits and flexible extension can simplify DIY repairs, battery replacements, or upgrades on gadgets, potentially saving on professional service costs for straightforward jobs.
Benefits and Buying Value

The value of this set stems from its targeted design, material specification, and the inclusion of accessories that address common repair hurdles.
Reuse and Low Maintenance
As a tool set made from chrome vanadium steel, it is built for repeated use within its stated application of non-precision maintenance. The tools themselves require minimal care beyond standard storage. The primary value in reuse comes from having a dedicated, organised collection of bits specifically matched to the screw types found in modern electronics, avoiding the need to purchase individual drivers for different projects.
Why Choose This Product
This set stands out for its specific combination of a high bit count (117), the stated 55-60 HRC hardness of its CRV bits, the practical advantage of magnetic retention, and the problem-solving flexible extension rod. It consolidates the tools needed for a wide range of electronic repairs into one organised package (available in black, blue, or red boxes). The focus on the precise hardness rating and material offers a concrete, source-supported differentiator from more generic tool kits, providing a logical basis for its suitability for the described repair tasks.
