Milwaukee 2101-21 M4 1/4 Hex Screwdriver Kit W/1 Bat

Product Information

Many cordless screwdrivers come with rechargeable batteries, and they tend to range between 4 and 8 volts. Since a cordless screwdriver requires much less speed and power than a drill, these lower voltages are adequate. The benefit of a smaller lower-voltage battery is that it fits in smaller places than full-size options and it helps make the screwdriver as light as possible while still being rechargeable.

The Denali screwdriver doesn’t boast many bells and whistles, but it did allow us to choose from one of three torque settings. We found that handy when inserting screws into materials with different densities—for instance, more torque when inserting screws in wood than in softer drywall. It also features an LED guide light, but we found it to be dim and unlikely to offer much illumination in low-light situations. There are a few slightly different methods to operating a cordless screwdriver, but here is a general usage guideline: Cordless screwdrivers don’t have the power to drive through a lot of dense material, so don’t plan on building an entire storage shed with one. However, they can be a good option for light to medium jobs like running screws to hang pictures on walls, tightening cabinet door hinges, and removing outlet covers and switch plates. We’re big fans of power tools that make DIYers’ lives easier, and cordless screwdrivers rate right up there at the top.Too much torque can break smaller, older, or low-quality fasteners. Fortunately, the best cordless screwdrivers have adjustable clutch settings to avoid stripping or breaking these fasteners. The clutch can also avoid overdriving the screw too deeply, which may also cause unwanted results.

A cordless screwdriver can reach and manipulate screws in small, awkward spaces much more easily than a manual tool can. If there is room for the tip of the driver to go onto the fastener, these powered screwdrivers help do the rest.The only real downside we noted was that the Denali tended to bog down a little when we inserted screws in wood. It did the job, but it took longer than it did on drywall. Still, this is a handy little cordless screwdriver to have around the house or to keep in the trunk of a car for when small jobs arise.
