The Milwaukee 2957-20 is an M18 FUEL 1/4-inch hex impact driver that adds ONE-KEY connected tool features to a compact fastening tool. It is sold as a bare tool. The buying decision is whether you need its control and tracking features, whether they suit your worksite, and whether you already own M18 batteries and a charger.

What the 2957-20 includes

Milwaukee Canada lists one 2957-20 impact driver and a belt clip in the box. Battery and charger are not included. Do not assume the tool-only SKU includes the batteries shown in a marketing image; check the exact retailer package and model number.

Specifications and controls

• Up to 2,000 in-lb torque and 3,900 rpm: Milwaukee publishes these ratings. They are not an independent comparison and do not predict outcomes for all fasteners or materials.
• 4.47-inch tool length: the stated bare-tool length may help with access; battery and bit add to the space needed.
• Four-mode drive control: selectable modes let the user tailor output; Milwaukee also describes a self-tapping screw mode that stops when the fastener seats. Read the manual and test settings on scrap.
• Tri-LED lighting: integrated lights illuminate the immediate workspace.
• ONE-KEY: the manufacturer describes functions for customizing, tracking and managing the tool, saving settings, and locking it out if lost or stolen. App availability, permissions and tracking depend on the service and configuration; confirm current details with Milwaukee.

Impact drivers use a 1/4-inch hex collet for compatible bits. They are primarily fastening tools, not replacements for a drill/driver’s adjustable chuck. For varied drilling, see our drill-versus-impact-driver guide.

Who should compare this model?

The ONE-KEY features may be relevant to tradespeople or teams that already manage tools digitally and have a real use for saved settings or asset tracking. For a homeowner driving occasional screws, those connected features may add little value compared with a simpler impact driver. This is a use-case distinction, not a claim that one model is faster or better in practice.

If you already own compatible M18 batteries, a bare tool may reduce duplication. If not, include the cost of a battery and charger in your Canadian comparison. Also consider the battery’s effect on weight and balance. Our kit-cost checklist covers tool-only purchases.

Before buying

1. Verify 2957-20 and distinguish it from older models or a 2957-22 kit.
2. Confirm which batteries, charger and case are included in the exact SKU.
3. Check ONE-KEY app requirements, current feature availability and any permissions you are comfortable granting.
4. Review manual, warranty, authorized seller and return terms.

Research-based view: The 2957-20’s clearest differentiator on paper is the combination of compact dimensions, four modes and ONE-KEY connectivity. It is most worth comparing when those functions solve a real worksite need. We have not tested driving speed, trigger feel, app performance, battery life or tracking accuracy.
