191-in-1 Professional Precision Repair Tool Kit with 4mm & 6.35mm CR-V Bits | Dual Handle

This 191-in-1 professional repair tool kit is a comprehensive solution designed for electronics repair centers, distributors, service teams, and wholesale buyers who require a complete, high-efficiency tool system for daily repair operations. With 164 precision CR-V bits and a full range of disassembly and protection accessories, this kit is built for high-volume, professional use across multiple repair scenarios.

The set includes 120 pcs 4mm CR-V bits and 44 pcs 6.35mm CR-V bits, covering a wide range of common and special screw types used in consumer electronics and household devices. All bits are made from heat-treated CR-V steel to ensure high hardness, wear resistance, and long service life, even under continuous use.

To support different working needs, the kit features a dual handle system with both 4mm and 6.35mm screwdriver handles, each paired with its matching extension shaft. A flexible extension shaft allows technicians to access deep, narrow, or angled screw positions that standard drivers cannot reach, significantly improving efficiency during complex disassembly.

For organized and efficient workflow, a magnetic screw memory mat is included to keep screws sorted and visible during repair, reducing mistakes and saving time. The magnetizer/demagnetizer enables controlled magnetism for easy screw handling, while the anti-static wrist strap protects sensitive electronic components from static damage.

This kit also provides a full set of opening and prying tools, including opening picks, spudgers, a metal spudger, and a pry tool, enabling safe screen and housing removal without damaging device surfaces. Additional accessories such as tweezers, suction cup, SIM card pin, cleaning brush, and cleaning cloth support detailed repair, cleaning, and component handling work.

Designed for professional environments, all tools are neatly organized for quick access, making this kit ideal for repair workshops, refurbishment factories, training centers, and after-sales service providers.
