Our Opinion

The Milwaukee 2101-22 can deliver a maximum of 44 in. lbs. of torque that is very sensible for a compact screwdriver. It has a two-speed gearbox which can operate at 0-200 revolutions per minute at low-speed setting and 0-600 rpm at high-speed setting.

The power and speed of this model from Milwaukee make for a high performing screwdriver. It will be able to handle more than just removing screws from toys. It can assemble and disassemble your furniture, install shelving and curtain rods, and other light to moderate tasks in and around your house.

It Uses the Innovative Red Lithium Battery

The 2101-22 screwdriver uses Milwaukee’s battery technology innovation. Milwaukee introduced the new batteries in 2010 It replaced their previous line of M12 and M18 lithium-ion batteries. Apparently, Milwaukee teamed-up with people from MIT to develop the Red lithium battery. The company did not really make the actual battery cells; they just made the actual battery pack better.

In battery innovation, the battery pack construction, the lithium-ion cells in the pack, and the electronics within the are the three major things to consider. To avoid overcharging of batteries which may cause it to get damaged, Milwaukee’s smart Red lithium-ion batteries have constant communication with the charger. This communication also happens during the actual use of the tool to prevent overheating of the battery and eventually cause both the battery and the motor of the tool to get damaged. It also no longer requires you to fully discharge the battery to be able to maximize the battery’s full capacity.

The thermal protection in the Red lithium batteries lets the battery stay cooler longer before it gets cut off. This means that you can use the power tools with Red lithium batteries for much longer especially since power tools need to operate continuously to finish the job.

Compared to the older batteries used in Milwaukee tools, the Red lithium batteries have 40% more run-time, 20% more speed, 20% more torque, and fade-free power. According to the company, you will be able to drill about 200 holes using the M4 before the battery completely drains. These packs can also run 20% cooler, can be recharged 50% more, and does not suffer from memory effect.
