Stubby Cordless Impact - Milwaukee Tool has a new line of small M12 impact wrenches that Milwaukee claims are the "industry’s first cordless stubby impacts" and also "the most compact cordless impact wrenches on the market".  The new FUEL M12 impact wrenches are very small, lightweight and powerful.  Full specifications for the 1/4", 3/8” and 1/2" models are listed below.

The new stubby impact wrenches are designed to replace pneumatic stubby impacts.  Cordless units have no hoses and no maintenance and provide close to the same performance.  Like other FUEL models, the M12 FUEL Stubby Impact wrenches are powered by Milwaukee Tool's POWERSTATE Brushless Motors along with the REDLINK Intelligence system to protect the battery and tool.  Each impact wrench model has a four-mode DRIVE CONTROL feature with the 4th featuring an Auto-Shut-Off Mode to prevent over-fastening of bolts.

Long-Term Use
These small and very ergonomic impacts are our new go-to tool for small tasks.  The M12 line has a slightly larger handle because the battery fits connect in the handle, but these tools fit our hands well and they are nicely balanced.  While it would be nice to see the fuel gauge on the battery, the Milwaukee M12 line has them on the tool.  This forces us to make sure the batteries are charged after each use.

The drive control is changed on the top of these units and is lit up by a light.  When you pull the variable speed trigger, the light turns on for a few seconds letting you know what mode you are in.  To change modes, you just push the button and the other mode will light up.  This did cause us a bit of confusion when we first started using them as we were switching them back and forth and when the next guy picked up the tool, he did not know what mode they were in.  While the drive control mode is cool looking, the long term question is when that area gets dirty or the cover on the button cracks, will it work as well.  I would much rather see a simple switch so one could visually see what mode they are in at all times.  There are times where we enjoy technology in tools and other times where we just want simple and reliable, in this case, if we had a choice, we would opt for a switch rather than a button for drive control.

On the other hand, these drive control buttons open up the door for Milwaukee to adapt their new ONE-KEY technology for these tools in the future.

If you think 12 volt tools cannot provide the power and run time you need, we suggest you try some out.  These days, they have improved and can be a great player in the market.  There is not a huge gamble on the tools as it is backed with Milwaukee's tool warranty for 5 years and the battery is backed for 2 years.
