Product Overview

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.

  • 21 position clutch with auto-shut off for improved torque control
  • Heavy-duty 2 speed gearbox - 200/600 RPM
  • Powerful motor: delivers 44 in-lbs of torque
  • 1/4 in. quick-change chuck for one-handed bit changes
  • On-board battery fuel gauge displays remaining run-time
  • Includes: (1) 2101-20 M4 screwdriver (1) screwdriver tip

M4 4-Volt Lithium-Ion 1/4 in. Cordless Hex Screwdriver (Tool-Only) is rated 3.5 out of 5 by 6.
Rated 5 out of 5 by from Milwaukee M4 Great for small to medium jobs, and fits in your back pocket too.

Rated 2 out of 5 by from Disappointed Used once to twice a day to change tooling--about 40 set screws. Works very well in terms of holding a charge, feels solid. However, it was dropped (on a concrete floor) the second day and the switch was damaged (repaired on warranty, though). A few months later, the highest torque setting produces less than 4 in. lb. Will be sending it in again.

Rated 1 out of 5 by from M4? Really? If you want to sell these make it M12 Firstly, I asked Milwaukee for this years ago. It responded with...we don't discuss new offerings. Fine. So I waited more. Then, ALAS! it's here! Ah...M-what? Four???! I can't believe it. Well, Mil, seriously I doubt these are flying off the shelves and it's because NO ONE wants a sole M4 platform battery and charger for one tool--especially when some of us are $100,000+ deep in M12 and M18. Please, for 2016, re-introduce this in M12. I promise I will be the first to buy it...and as a bonus, get it done by June and I'll even buy the kit: batteries and charger even though I probably own 50+ charges and 100+ batteries. Best wishes in 2016 and Happy New Year! Thanks for everything else M12/M18 this year. Great stuff!!

Rated 5 out of 5 by from Works great for laptop repair and lower torque applications I bought this because I already own the kit with two batteries and a charger, and decided to keep one for work and one for home. The battery life is great. It's lightweight and good for everyday use, and it's perfect for what I had originally intended: laptop and PC repair. Many years ago, Craftsman made a mini cordless screwdriver with high speed and low torque that was perfect for field service computer repair. Unfortunately, I left mine on the trunk of my car while loading parts and it suffered a horrible fate on the highway. Ever since, I have been looking for a suitable replacement. Most cordless screwdrivers operate below 200 RPM which is about what you can achieve by spinning the shaft of a hand screwdriver between your thumb and fingers. Leave it to Milwaukee to make a much improved version of the high speed / low torque cordless screwdriver. My co-worker has a competitors heavy 4v that (apparently) is made of cast iron and lead. not ideal for precision work. I haven't really tested the upper end of the torque range because I have an M12 drill and impact driver for that. Bottom line: Would I buy it again? I already have!
