The 6 alternatives listed here were chosen because their specifications overlap with the original model. Each option shares key traits like brushless motors and 1/4-inch hex chucks, but varies in weight, length, and included components. You can compare these specs to find the best fit for your workflow.

Comparing these alternatives to Milwaukee
DEWALT 20V MAX XR 1/4-Inch Brushless Impact Driver
The DEWALT 20V MAX XR model offers a lighter, more compact body than the Milwaukee. It weighs just 2.2 pounds and measures 5.1 inches in length, making it easier to handle in tight spaces. However, it is sold as a bare tool. You must already own a 20V battery and charger. This option suits users who want maximum torque and portability without buying a new power system. It trades the included accessories of the Milwaukee for a smaller footprint and existing battery compatibility.
DEWALT 20V MAX XR Brushless 1/4 In. Impact Driver
This DEWALT 20V MAX XR unit provides higher torque and speed control for professional applications. It is significantly larger than the Milwaukee, measuring 11.9 inches long and 9.5 inches high. The trade-off is size for raw power. It lacks the compact design of the Milwaukee but offers superior illumination and detailed control. This tool fits users who prioritize performance over portability. It is a robust choice for heavy-duty fastening where space is not a constraint. You get a powerful tool but sacrifice the ease of use in confined areas.
DEWALT ATOMIC 20V MAX 1/4 In. Impact Driver Kit
The DEWALT ATOMIC kit includes both a battery and charger, similar to the Milwaukee. It delivers high torque in a compact form factor suitable for tight spaces.

BLACK+DECKER 20V MAX Brushless 2-Tool Combo Kit

The impact driver has a 2.0 Ah battery, matching the Milwaukee’s capacity. It is a good choice for DIYers needing a versatile set. The trade-off is that it is less specialized for heavy-duty impact tasks. You get more tools for your kit but less focused performance on impact driving alone. It suits users who need drilling and driving capabilities in one package.
Ryobi ONE+ HP Compact 1/4 in. Impact Driver
The RYOBI ONE+ HP model is an 18V brushless impact driver with a 5.0 Ah and 1.5 Ah battery option. It is lighter and more portable than the Milwaukee, weighing 5.6 pounds. It fits users who value portability and existing RYOBI battery compatibility. The trade-off is slightly less raw power compared to the Milwaukee’s 1,600 in./lbs. It is ideal for light-duty fastening and occasional use. This tool offers a practical balance of power and weight. You get a reliable option for home projects without the bulk of larger professional kits.
Greenworks 24V Brushless 1/2-Inch Drill Driver
The Greenworks 24V Brushless Drill Driver is a different tool type, focusing on drilling rather than just impact driving. It features a 1/2-inch metal chuck and delivers 530 in./lbs. of torque. It is lighter than the Milwaukee at 2.43 pounds. This option suits users who want 24V performance in a compact body.
