Ahead of Amazon’s October Prime Day 2026 event, Lifehacker on September 25 published a roundup of discounted DIY tools, including DeWalt tool sets discounted up to 51%, cordless saws, and bit accessories. The sale, officially called Big Deal Days, begins Tuesday, October 6, 2026, at 12:00 a.m. PT / 3:00 a.m. ET and runs for two days. For shoppers planning fall DIY projects, the roundup highlights discounts on tools that are otherwise expensive at regular price.
The largest discounts in the roundup fall on tool sets. The DeWalt 20-volt oscillating multitool set is listed at $157, 47% off its regular price, and includes the multitool, a 2-amp-hour battery, a charger, three starter blades, a sanding attachment, and sandpaper. According to Lifehacker writer Becca Lewis, the tool can cut metal, wood, plaster, drywall, PVC, and tile, and can also be used for sanding and polishing. The DeWalt 192-piece mechanic’s tool set is listed at $169.94, 41% off, with ratchets in three drive sizes, SAE and metric sockets, spark plug sockets, driver bits, hex wrenches, and adapters. At the entry level, the Craftsman 10-piece mechanics tool set is listed at $14.99, 51% off, including a 3/8-inch ratchet and nine metric sockets.
On cutting tools, the DeWalt 7 1/4-inch cordless compound miter saw is listed at $296.65, 20% off — a tool-only deal that requires a separate DeWalt 20-volt battery and charger. The Husqvarna 14-inch 225i battery-powered chainsaw is listed at $264.99, 30% off, and includes a chain, battery, and charger; according to the listing, it can make up to 190 cuts on a single charge. The DeWalt 20-volt jig saw is listed at $139.90, 41% off, also as a tool-only purchase.
Accessories carry the steepest percentage discounts in the roundup. The DeWalt 35-piece impact bit set is listed at $29.98, 66% off, the largest discount cited. The Bosch 41-piece drilling and driving combo set is listed at $21.47, 57% off, with drill bits up to 3/4 inch, driver tips, an adapter, and a case. The Milwaukee socket adapter set is listed at $8.21, 47% off, covering 1/4-inch, 1/2-inch, and 3/8-inch sockets.

04 / WHY THE TIMING MATTERS
Fall projects meet a short sale window
For homeowners and DIYers, tools can be a significant expense. The event lands ahead of seasonal maintenance, yard work and winterizing projects, but the buying window is brief.

What to know before the sale opens
Why Fall Tool Discounts Matter
Quality power tools are a significant expense for homeowners and DIYers, and Prime Day events are among the few predictable windows when brand-name tools like DeWalt, Bosch, Milwaukee, and Husqvarna see substantial price cuts. Lewis notes that several of the highlighted deals — such as the miter saw and jig saw — are tool-only purchases, meaning shoppers already invested in a brand’s battery ecosystem can expand their collection at a lower per-tool cost, while first-time buyers must factor in the added cost of batteries and chargers.
The timing also aligns with fall home maintenance and yard work: the roundup points to uses like cutting up downed limbs, repairing fencing, and winterizing projects. Because the sale lasts only two days, shoppers comparing prices need to act within a narrow window.
How Prime Day Big Deal Days Works
Amazon’s October Prime Day — branded as Big Deal Days — is a two-day sales event open to Prime members only. According to Lifehacker, the October 2026 event starts Tuesday, October 6, 2026, at 12:00 a.m. PT / 3:00 a.m. ET and offers discounts on thousands of products across the site. It functions as a shorter, fall counterpart to the main summer Prime Day. Lifehacker’s roundup was published on September 25, 2026, roughly ten days before the event, as part of its advance deal coverage.
“This bit set is a good starter set because it has both driver tips and drill bits, so you could use it with a drill for hanging pictures or curtains, or for assembling flat-packed furniture.”

Pricing and Availability Caveats
Several details remain uncertain. Lifehacker’s own disclosure states that deal pricing and availability are subject to change after publication, and the site may earn a commission from links — so listed prices may not hold through the event. The roundup was published before Big Deal Days began, and it is not yet clear whether these prices will drop further during the official sale, whether stock will hold for the full two days, or whether comparable deals will appear from other retailers such as Home Depot or Lowe’s, which typically run counter-promotions. The regular “usual” prices cited for each discount percentage are as listed by the source and have not been independently verified. Some highlighted items, including the saws and certain bit sets, are tool-only deals requiring separate battery and charger purchases, which changes the total cost.
When the Sale Begins
Big Deal Days opens Tuesday, October 6, 2026, at 12:00 a.m. PT / 3:00 a.m. ET and runs two days. Shoppers will need an active Amazon Prime membership to access the discounted prices. Expect expanded deal coverage from Lifehacker and other outlets during the event itself, including lightning deals and price-tracking updates. For any tool purchase involving outdoor power equipment like chainsaws, follow manufacturer safety guidance and protective equipment requirements; for home projects involving electrical or structural work, licensed professionals remain the recommended route.
