  • Heavy-duty full metal gearbox – This feature gives you maximum torque and incredible durability that is hard to find on many other wrenches today. A feature like this is mostly present on high-end models manufactured by top brands but Milwaukee showed innovation and style to add this to their M12BIW38-0 tool. It makes this tool one that any DIY or professional must own.
  • ⅜ inch square drive – A tool that offers universal use is every DIYer and professional’s dream. This feature means you can use this tool with universal sockets giving an edge over other tools.
  • Optimized handle – This feature means you are in control of the tool all the time because you’ll have a tight grip. This minimizes the risk of injury because many people who work with power tools get hurt when they lose control. It is great to see a company that takes the safety of its users very seriously.
  • Runs using a RED LITHIUM- battery technology – This incredibly strong battery gives you twice the battery life, twice the runtime, and 20% more power. Not only will you work quicker, but you can work for longer too thanks to its amazing durability.
  • REDLINK Intelligence – When you use a tool like a wrench for a very long time, it might overhead. This feature allows you to use your wrench without worrying about it overheating which prolongs its lifespan and increases performance.


  • Innovative design – The mechanism design that Milwaukee went more means you can fasten quicker allowing you to finish plenty of jobs in a day.
  • LED light – Milwaukee M12BIW38-0 has an LED light that is built into it which enables you to work in dark rooms. Sometimes you can find yourself in places that are poorly lit and this feature comes in handy for such occasions.

  • Flexible battery system – The tool can work with all Milwaukee M12 batteries saving you a fortune. If you own any of these batteries at home, all you have to do is spend money buying the tool and not have to buy the batteries all over again.


  • Battery-powered tool – The only thing one might find frustrating is the runtime. Since it is battered powered which is the approach many companies are taking those days, the power stops when the battery runs out and needs to be charged. It is different from corded tools that will give you unlimited power as long as they remain plugged into a socket.
  • Price tag – Anyone looking to buy a Milwaukee tool has to know that they are cheap. They are some of the most expensive products on the market and this tool divides opinion as many people find it a bit expensive.
