Specifications side by side

How to choose the right one

1. Check the chuck size

   The drive size determines which sockets you can use. A 1/2-inch drive fits standard automotive and general mechanical fasteners. The Milwaukee M18 and DEWALT DCF961B both use this size. It is versatile for most jobs. A 3/4-inch drive handles larger, heavier bolts. The DEWALT DCF964B uses this larger drive. Choose 1/2-inch for everyday tasks. Pick 3/4-inch only if you work with heavy construction or large industrial equipment regularly.

2. Verify battery compatibility

   Most tools here are sold as bare tools. This means they do not include a battery. You must already own compatible batteries from the same brand. The Milwaukee M18 requires 18V packs. The DEWALT and Makita models need 20V or 18V systems. Check your existing battery inventory first. Buying a bare tool saves money if you have the power source. If you lack batteries, you will need to purchase them separately to use the tool.

3. Consider motor efficiency

   Brushless motors offer better efficiency and longer life. They use less power for the same output. The DEWALT DCF961B, DCF964B, and Makita XWT08Z all feature brushless motors. This design reduces heat and wear. The Milwaukee M18 is also a high-performance option. Brushless tools often provide more run time per charge. This matters if you work on large sites without easy access to charging stations. It is a key spec for long-term value.

4. Assess weight and size

   Weight affects comfort during extended use. The Milwaukee M18 weighs 5.95 pounds and measures 10.5 inches long. It is the lightest and most compact option here. The DEWALT DCF964B is the heaviest at 9.04 pounds. Heavier tools may cause fatigue in tight spaces. If you work in confined areas, choose a lighter model. The Milwaukee fits smaller hands and tighter spots better. Compare the dimensions in the specs to ensure it fits your workspace comfortably.

5. Review included accessories

   Check what comes in the box. All listed tools are sold as impact wrenches only. They do not include batteries, chargers, or cases. You need to verify your setup before buying. The Milwaukee M18 is a bare tool. The DEWALT and Makita options are also bare tools. You must supply your own power source. This keeps the initial cost lower if you are already invested in the ecosystem. Plan your purchase to include necessary batteries and chargers separately.
