Buying advice: power tools
- Major platforms each cover hundreds of tools. Choose one with the specialty tools you may need later.
- Brushless motors are more efficient and durable. Brushed tools are fine for occasional light use.
- Kits include batteries and a charger. Once you own batteries, bare tools are much cheaper.
- 12V tools are compact for light work. 18V or 20V max tools handle most home projects. Higher-voltage platforms suit heavy cutting.
- Check tool and battery warranty lengths and whether registration is required.

Which drill is more powerful, DeWALT or Milwaukee?
At comparable price tiers, Milwaukee M18 FUEL brushless drills are more powerful than DeWALT XR brushless. At budget tiers (brushed motors), the difference is smaller. For drilling through concrete and hardwood repeatedly, Milwaukee FUEL has the edge. For standard home use (drywall, softwood framing, assembly), the difference is imperceptible.
If I already have DeWALT batteries, should I switch to Milwaukee?
The battery platform transition cost makes switching rarely worthwhile. If you have DeWALT batteries, buy DeWALT tools. The performance difference between professional-tier DeWALT XR and Milwaukee FUEL is real but small, not worth replacing a battery library over.
