Set Xiaomi MJDDLSD003QW 170 RPM gris

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
