The Wera comes with six bits, including two Phillips-head bits, two square drivers, and two slotted drivers. The shaft also doubles as a ¼-inch nut driver. The screwdriver has a collar direction adjustment, as well as a lanyard hole for a wrist strap or hanging cord. However, it doesn’t have any onboard storage, so you should keep the case on hand for easy access to bits.

Screwdrivers are essential pieces of kit, used by DIYers and professionals alike. Ratcheting systems give you a mechanical advantage and make the job much easier to complete.Not all screwdrivers will have their torque rating clearly displayed, but durable models can handle around 50 newton meters (nm) or about 36 foot-pounds of torque. Taking a screwdriver beyond its torque capacity will usually break the pawl or shave teeth off the ratcheting gear, making the screwdriver useless. Length

We used the Williams screwdriver to insert screws in a variety of wood types, and its ratcheting action remained smooth and sure—even when we used force. The directional collar switches with ease, and the shaft head features a magnet that holds bits in place. The long, thin design of this screwdriver is well suited to reaching fasteners in tight spots while exerting pressure. Ratchets are great and save you a lot of time, but the best ratchet screwdriver, like the Wera Kraftform, will have a switch to change direction without removing the tool from the screw. The Workpro Ratcheting Screwdriver features a nonslip grip and solid feel, making it easy to get a firm grasp on the handle. The tool stores six 3.5-inch double-ended bits in its base, which gave us 12 different bits to choose from, including slotted, Phillips head, star, and Torx. The bits themselves are magnetic—rather than the head—but they remained firmly in the tool, even when we shook it upside down. We tested the Workpro by inserting screws in a variety of wood types, and it came through with flying colors—even when we used maximum force and dense walnut wood. We then tested the tool on a range of fasteners and found the bits are well made and appear to be hardened steel. Most ratchet screwdrivers use ball detents or magnets to hold their bits in place. In either case, removing the bit simply requires pulling the bit straight out of the shaft. Why Trust BobVila

Milwaukee Systems

The Wera ratcheting screwdriver feels solid in the hand, and one of the first things we noticed was its nonslip, ergonomic grip that’s contoured to help the user get a firm grasp. The bit storage base slid out easily with just a light push of the button on the bottom, making it easy to select the bits. We inserted screws in pine, ash, and walnut boards, and the screwdriver held up to all densities. There are a handful of styles of ratcheting screwdrivers, so the results of our tests and this comprehensive guide let you know what’s out there before you start shopping. The main difference in style is how each screwdriver stores its interchangeable bits. There are benefits to each style, so it’s worth giving some consideration. Bits in the Handle We also tested the wire stripper, and it easily removed the insulated sheath from household electrical wires, making the Milwaukee a beneficial tool for DIY electricians as well as for assembling furniture and other projects.

We found the Megapro well suited for use by those with large hands. Its handle features rubber inserts and is comfortable to grip, but it might be a little large for someone with smaller hands. The end cap slides out for easy bit retrieval, and the double-ended bits make it handy to find the right bit without needing to carry extra bits around. The directional collar is easy to switch, and the ratcheting action is smooth. Don’t expect frills or extras with the Williams T-Handle Ratcheting Screwdriver, because you won’t find any. What you will find is a solid screwdriver that comes with a long shaft and accepts standard ¼-inch bits. It comes with just one Phillips-head bit.On the larger Klein Tools screwdriver, using strong force to insert a screw into a walnut board was more than it could take, and the ratcheting mechanism broke. Bob Vila has been America’s Handyman since 1979. As the host of beloved and groundbreaking TV series including “This Old House” and “Bob Vila’s Home Again,” he popularized and became synonymous with “do-it-yourself” home improvement. Most ratcheting screwdrivers use a gear-and-pawl system. Depending on the direction you set the screwdriver to, the pawl will engage with the gear, forcing the tip to rotate with the handle. When you twist the screwdriver in the other direction, the pawl skips over the gear’s teeth, rotating the grip independently of the tip.

The benefit of storing the bits in the handle is that it’s harder to lose them. As long as the cap stays shut, the bits are secure, even if they pop out of their clips. The downside is that switching between bits stored in the handle does create some downtime. Also, these bits are often smaller and harder to grip. Bits on the HandleThe Milwaukee is a solid little tool, and its ratcheting action is among the smoothest of the models we tested. This didn’t come as a surprise, since the Milwaukee brand is well known and has a great reputation for making quality tools. The head features a strong magnet that holds the bits in place, and the directional collar is well made and easy to switch. As opposed to storing your bits inside the handle, several models come with storage on the handle. These models have slots or holes for holding the bits right in the grip. They either clip into place or slide in from the bottom of the handle. The most common style of ratcheting screwdriver stores its bits inside the grip. Often, there is a cap that threads on and off or pops out of the handle, providing access to the driver bits. Multiple bits clip to a removable ring, allowing you to choose the appropriate bit or store it away securely. Other models have bit-clips built into the cap.
