This cordless 4-volt Screwdriver incorporates the latest Milwaukee core technologies in motor, Red Link Intelligence electronics and Red lithium 2.0 batteries, increasing the tool’s power and run-time, while shrinking its size. It has a 21 position clutch with auto shut-off that stops rotation of the bit once the desired torque setting is met. The quick-change chuck allows for one-handed bit changes, and a snug bit grip prevents dropped screws when the screwdriver is inverted. Drill mode easily drills pilot holes or removes damaged screws.

Rated 4.6 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Excellent service and product Powerful and very easy to use. Highly recommend product December 10, 2014
Rated 4.0 out of 5.0 by One con... Great features for the price and works well. During use the handle too easily moves out of desired position and can loss of control. October 14, 2014
Rated 5.0 out of 5.0 by Great quality in the Milwaukee Tradition. I had the first model of this Milwaukee Cordless Screwdriver, and have missed using it as the battery died after 5 years of use. This new Lith-Ion lasts longer on a charge. Great for hanging curtain rods, wiring receptacles, taking appliances apart, working in car, getting into those hard to reach places Really any where you have to turn the screw many times and you do not want to strip the threads. Saves time in hanging hinges when you do not need the power of the impact driver. The extended length phillips bit included is well made. Hope to find additional bits of that length and quality. Surprising power with two speeds, several locking features to prevent the screwdriver from turning on in your tool box. The bending feature is great for the extra push. I have had the tool for a Month used four of five times. Its a MILWAUKEE tool I am glad to have back in my took box. March 4, 2014
Rated 4.0 out of 5.0 by Great Summary I love the fact that the battery lasts longer than expected. It is not super fast in speed but just perfect or projects around the home. March 18, 2014
Rated 5.0 out of 5.0 by Great little screwdriver For everyday use you can't beat this little driver. Compact and powerful and the battery lasts forever. I bought this one to replace one I've had for 10+ years and the battery finally failed on me. It was cheaper to buy the entire kit than replace the battery. March 4, 2014
Rated 5.0 out of 5.0 by Excellent tool I have had three models of this tool for thirty years. They all still work. This one is an excellent addition to the product line yielding excellent torque and power for a small tool and useful for the vast majority of projects. I usually reach for this one first. As usual, Milwaukee quality. February 11, 2014
Rated 4.0 out of 5.0 by good battery performance replaced b & d unit that wouldn't hold a charge and had less torque. li - ion battery performs much better and at a slightly higher voltage than old driver. February 11, 2014
