Set Xiaomi MJDDLSD003QW 170 RPM Grey

The Xiaomi MJDDLSD003QW 170 RPM Grey is an electric precision screwdriver set with a straight-handle design and a compact aluminium alloy unibody case. The set includes a rechargeable lithium battery, 24 S2 steel precision bits in major tip types (Pentagon, Phillips, Slot, Torx, Tri-Wing) and six 45 mm long bits for deep or narrow applications. The tool features a magnetic motor, an all-metal gearbox and a Type-C charging port with an LED charging indicator.

Advantages

The screwdriver delivers up to 170 RPM with bit concentricity of no more than 0.2 mm when rotating, enabling greater precision. A long-lasting built-in battery allows processing of 400+ small screws on a full charge. The kit contains 24 high-hardness (up to 60 HRC) S2 steel bits and six extended 45 mm bits for deep-hole tasks. Two torque settings (0.05 N·m and 0.2 N·m) protect delicate electronics; power-off mode enables manual screwing. The anodised aluminium case and non-slip 3D grip improve handling and durability.

Suitable for

• Repair and maintenance of smartphones and tablets
• Small household electronics and smart speakers
• Watches, glasses and other precision objects
• Laptops, game consoles and other consumer electronics

Recommendations

Charge the screwdriver with a compatible USB-C cable before first use. Use the correct bit type and size for each screw to avoid damage. For safety and battery longevity, avoid exposing the tool to moisture or extreme temperatures and follow the manufacturer’s battery and charging precautions.
