The BLACK+DECKER BD40K4-IN is a compact and user-friendly 4 V Max lithium-ion cordless screwdriver built for home and DIY tasks. Employing a “Push & Start” design, it activates with a gentle push—no On/Off switch required—and boasts an advanced E-Clutch with Torque Detection System (TDS) that delivers both soft (2.5 Nm) and hard (5 Nm) torque settings, automatically stopping when screws are fully set to prevent overdriving. Its 6.35 mm (¼″) hex chuck supports quick bit changes, and the integrated LED worklight improves visibility in tight or dimly lit areas. The 1.5 Ah Li-ion battery charges in approximately 1.5 hours (via micro-USB), and battery-level LED indicators keep you informed. Compact (about 240 g) and ergonomically designed, this screwdriver comes in striking orange-black colors, includes four screwdriver bits (PH0, PH2, SL3, SL6), a micro-USB charging cable, and a sturdy plastic storage case—backed by a 1-year warranty.
