This model is battery operated, but the battery is inside the tool. One charger is included with your SD Semiautomatic Driver.

At only 1.1 lbs when loaded with the bit cartridge, the SD Semiautomatic Driver is the perfectly lightweight, yet versatile and powerful tool and will become an indispensable go-to for any household.

Typical screwdrivers require keeping up with individual bits, which get lost or dropped easily when transitioning from one to another. The Semi-Automatic Driver with rapid bit index is a sure-fire way to shoot through screwdriving tasks around the house. What makes the WX254L Semi-Automatic driver unique is the bits are never lost! The WX254L includes two rapid reload cartridges that house 6 common screwdriving bits each, making them easy to access and even easier to change. Simply go from drilling a starter hole, to driving a Phillips screw, to driving a flat head screw in a matter of seconds with the semi-automatic bit changer. It's as easy as choosing the bit, rotating the cartridge, and shutting the chamber – you are cocked, locked and ready to drive some screws! When the trigger is pressed, an LED light automatically lights the task for better visibility in dark or hard to reach areas. The compact size allows the SD driver to fit into tight spots where a clunky drill is too big for the task. This SD driver is perfect to keep close at hand in the kitchen junk drawer or handy tool bag.

The SD Semiautomatic Driver comes with two rapid reload bit cartridges, each pre-loaded with 6 of the most common 1" long 1/4" hex bits, including one T10 drill bit, one T20 drill bit, one H3 drill bit, one H4 drill bit, one H5 drill bit, one screw starter drill bit, one P0 drill bit, one P1 drill bit, one P2 drill bit, one SL4 drill bit, one SQ1 drill bit, and one SQ2 drill bit. You can customize your cartridges with any 1" long 1/4" hex bits, which can be purchased at any local hardware or home improvement store.

The Worx SD Semiautomatic Driver makes changing bits fun. To change the bit to another in the same bit cartridge, slide the cover on the top of the SD Driver back and slide it forward again to expose next bit in the bit cartridge chamber. You can also slide the cover back and manually turn the bit cartridge to the desired bit before closing the cover to advance it.

To change the bit cartridge, slide the cover on top of the SD Semiautomatic Driver back, and press against the underside of the orange bit cartridge. It will pop out and you can insert a different cartridge. You can also customize the cartridge by replacing any of the bits. The cartridges will hold 1" long 1/4" hex shank screwdriver bits.

The battery will recharge in about 5 hours.

Yes, there’s an LED light to help you see what you’re working on.
