How to choose the right one
-
Check voltage needs
Voltage determines the power available for your tasks. You should match the voltage to the fastener size and material. The Milwaukee M18 Mid-Torque 3/8" Impact Wrench operates at 18 volts. This higher voltage suits heavy-duty bolts and structural work. The ACDelco G12 kit runs at 12 volts. This lower voltage is ideal for smaller automotive fasteners. You must choose the voltage that matches your specific job requirements for optimal performance.
-
Compare included tools
The number of tools in the kit affects versatility. You need to decide if a single tool or a combo is best. The Milwaukee kit includes only the impact wrench. This is sufficient if you already have other tools. The ACDelco kit includes an impact driver and ratchet wrench. This combo offers more variety for general tasks. You should select the kit that provides the tools you actually use most often.
-
Evaluate motor type
Motor type influences efficiency and durability. Brushless motors generally offer longer runtime and less maintenance. The ACDelco G12 kit features a brushless motor.

-
Assess chuck size
Chuck size determines the socket or bit compatibility. You must ensure the chuck fits your standard accessories. The Milwaukee M18 uses a 3/8-inch chuck. This size is standard for many impact wrenches and sockets. The ACDelco kit includes a 1/4-inch chuck for the driver. This is typical for screwdriver bits. You should verify that your existing sockets and bits match the chuck size of your chosen kit.
-
Review battery capacity
Battery capacity indicates runtime per charge. All kits on this list include 2.0 Ah batteries. This capacity provides a balanced mix of weight and power. You should consider if you need additional batteries for long jobs. The Milwaukee kit includes dual batteries for extended operation. The ACDelco kit includes single batteries. You must plan your workflow around the number of batteries included in the package.
