Item Overview

Craftsman is a value-oriented, quality brand, and this heavy-duty CRAFTSMAN CMCF900M1 impact wrench offers great deals at a low price. With 0-2500 impacts per min, up to 350 foot/pounds of torque, and a large battery included, you’ll have everything you need to keep going.

The 4Ah battery has a substantial charge, so you won’t have to think about charging it after each working session. The battery is also “multi-chemistry,” which is just a polite way of saying that it’s a regular lithium-ion battery if you don’t know what that means.
Overall, the Craftsman high-duty impact wrench is suitable for home mechanics and DIY enthusiasts, but it should not be used for heavy activities.

CMCF900M1 Impact Wrench pros & Cons

  • Unbelievable value
  • Excellent torque/dollar
  • the battery charges quicker than most impacts drivers on the Market and stays charged longer.
  • Because of the dented anvil, swapping sockets is more difficult.
  • When you open the package, it can be sticky. Because of the tool alone, the inside of the box can be distorted. Two white straps held the object that was destroying the cardboard case in place.
  • a slight downside is large and heavy


The torque wrench is more significant than expected, but it feels strong in hand. It is easy to cut lug nuts—plenty of torque and fuel for automotive tasks. The torque wrench pictures are a little misleading in that the business end of the tool is not black as it appears in the photos. It’s more like a dark grey. This has no impact on the wrench’s functionality.
Full disclosure: my only complaint is that a power tool of this caliber did not come with a case or pocket, which is surprising given how difficult it is to find one that matches a torque wrench. I really wouldn’t swap this for any of the other cordless torque wrenches under $200. I wholeheartedly recommend this method!


Are Craftsman impact drivers good?

The impact driver has a 3-speed gearbox and a maximum torque of 1700 in/lbs for challenging work. At speed 3, the full revolutions per minute is an impressive 2,900 RPM. At 2.1lbs, this tool performs admirably for its size. Both tools’ LED work lights were bright and well-placed.

What is the Country of origin Craftsman?

Are impact wrenches worth it?

An impact wrench and the necessary compressor would be costly ONLY till you were used. Craftsman makes life much more straightforward. Even if you think you’ll need it for a few jobs right now, once you have it, you’ll discover other jobs.
