Frequently Asked Questions

  • Does this come with a battery and charger?

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

  • How much does the SD Semiautomatic Driver weigh?

    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.

  • What makes the SD Semiautomatic Driver different than a typical screwdriver?

    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.

  • What size bits does the SD Semiautomatic Driver use?

    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.

  • How do I change the bits?

    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.

  • How long does it take to charge the battery?

    The battery will recharge in about 5 hours.

  • Does the SD Semiautomatic Driver have a light?

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

Rated 5 out of 5 by from Best tool I've ever bought! I bought this tool several years ago. I thought it might be a gimmick or cheap but figured I'd try it since it was inexpensive. I have used this tool almost daily for 5 or 6 years. I work as a cable technician and have used it at work and at home. It has saved me countless trips to my truck to get the right tool, it has saved me countless hours of searching through my tool bag for the correct tool. I have recommended this tool to several coworkers, many of whom have bought it. They all love it too! My advice is to get this thing and never loan it to a friend or neighbor, because you won't ever see it again!

Rated 5 out of 5 by from This screwdriver is plain genius! I was unaware of Worx brand tools but saw an add for the SD screw driver and immediately went out and bought one. 6 Months later and I'm extremely happy with it. It has all the most common bits that you would need without having to fumble or look for lost bits. plenty of power, I use it often and rarely have to charge it. There is nothing negative I can say about the product its truly innovative. Yes it costs a little more than competitors but its well worth the extra money. People who have negative reviews are inexperienced or have a lack of knowledge on tools. It's not a drill driver its a power screw driver which has plenty of torque to do the right job. I look forward to seeing new products from this company and wish I had more money to buy other tools form them.

Rated 5 out of 5 by from Just what I Ordered Ordered online (goofed by inadvertently ordering Worx w/screw holder 1st) and waited for both items to arrive.

Rated 5 out of 5 by from Handiest Screwdriver Ever! Only had this a few weeks and it’s become my “go to” screw driver. Best part is I now have choices of the right bits for the job. With the on tool bit revolver I never have to search for the right one. BONUS: The on tool light makes screw and tool alignment exact the first time.

Rated 5 out of 5 by from Great Idea What a great idea. The ability to choose the tool head by simply rotating the cartridge is such a time saver. Not having to change out the tool every time you need to go from a phillips head to a flat head to a ............ is a great time saver. It also means you just need to take this driver to the job site instead of multiple tools and then having to search through your tool bag to find the right one. Great tool at a great price.

Rated 5 out of 5 by from Best on the Market I have two of these drills. They are used daily for several hours in my business. Long battery life, lightweight and ergonomically correct. Great idea that all bit sizes are inside the drill itself. No need to hunt down the bit you need. Top Quality construction.
