This 4V MAX cordless screwdriver delivers simple push button, power assisted speed in one of the most compact integral battery designs available. The 300 rpm (no load) motor drives screws 4x times faster than a standard fixed screwdriver making it perfect for free run, low torque applications, including electronics repair and installing switch plates. When additional power is required, the motor engages an automatic spindle lock that stabilizes and protects the gears for manual torqueing. The 1.5Ah lithium ion battery offers long lasting reliability with USB charging and 3 stage LED battery status indication. LEDs activate automatically when in use, improving visibility to the working surface. The set includes (6) 1 in. bits and (1) 1.5 in. bit extension for added length and a quick-change locking collet for reliable hold and simple changeover of bits.
