How to Shop DEWALT Deals
- Know what tool only means. Many DEWALT deals are bare tools without a battery or charger. Pair them with a battery deal if you’re new to the system.
- Pick brushless for heavy use. XR brushless tools like the DCF845 run cooler and longer than brushed models, which matters if you use them often.
- Stay on one battery platform. All 20V MAX tools share batteries and chargers, so sticking with one system keeps your garage simpler.
- Watch the clock on October 7. Prime Big Deal Days ends at 11:59 p.m. PT on October 7. If something you want isn’t discounted, look again around Black Friday on November 27.
