Compact precision screwdriver

The DeWalt B1 Pro is a cordless mini electric screwdriver built for delicate electronics work. Its pen-shaped body and OLED display show torque level, rotation direction and battery status at a glance. The kit includes 48 magnetic S2 steel bits across 12 profiles and a built-in shadowless LED light for low-lit areas.

Verify your device screws

Confirm the fasteners in your phone, laptop, camera or watch match the 1/4-inch hex bits supplied. The adjustable torque ranges from 0.05 Nm to 0.2 Nm with a 3 Nm manual override, so ensure that range covers the sensitivity of your components. The tool runs on an internal 350 mAh lithium-ion battery charged at 220 V.

All-metal gearbox and daily use

An all-metal gearbox delivers a steady 200 rpm for consistent driving and removal. The 6.7-pound kit packs into a display case that holds the driver, bits and accessories together. A single charge provides 2-3 hours of runtime or roughly 500 screws, while overheat protection safeguards the battery during extended sessions.
