DEWALT Warranty: 3-Year Coverage, Free Service and Claims
DEWALT’s famous “3-1-90” promise is one of the strongest in power tools — but each number means something different, and the fine print decides whether your repair is free.
A dewalt warranty bundles a 90-day money-back guarantee, a year of free service, and a 3-year limited warranty (7 years on select products) against defects in materials and workmanship. This guide breaks down each tier, the exclusions that deny claims, and exactly how to get your tool serviced.
Quick Answer: DEWALT Warranty at a Glance
Every DEWALT power tool carries three layers: a 90-day money-back guarantee (full refund if unsatisfied), 1-year free service (free maintenance and worn-part replacement from normal use), and a 3-year limited warranty repairing defects in materials or workmanship free of charge. Select products state a 7-year limited warranty instead. Coverage applies only to products bought from DEWALT or authorized sellers. Questions: 1-800-433-9258, 7 AM–11 PM ET daily.

DEWALT’s Three Warranty Tiers in Detail
90-day money-back guarantee: if you are not completely satisfied with the tool’s performance for any reason, you get a full refund. Handle it through the retailer first if you’re inside their return window; otherwise a DEWALT factory service center (FSC) can process it. Proof of purchase showing when and where you bought it may be required.
1-year free service contract: for the first year, maintenance and replacement of worn parts caused by normal use are free. A service center diagnoses the tool first — if the problem turns out to be abuse or an excluded cause, charges may apply after inspection.
3-year limited warranty: DEWALT repairs, without charge, any defect due to faulty materials or workmanship for three years from purchase (or delivery, whichever is later). This is the core manufacturing-defect coverage most claims fall under.
What Is the DEWALT 7-Year Warranty?
Products explicitly marked with a 7-year limited warranty get seven years of defect coverage under the same terms as the 3-year tier: free repair of defects in materials or workmanship, original purchaser only, wear and abuse excluded. Check the packaging and product page — the 7-year term applies only where DEWALT states it.
Your dewalt warranty card confirms which tier your specific tool carries.
| Tier | Length | What it does |
|---|---|---|
| Money-back guarantee | 90 days | Full refund if unsatisfied, any reason |
| Free service contract | 1 year | Free maintenance + normal-use worn parts |
| Limited warranty | 3 years | Free repair of material/workmanship defects |
| Limited warranty (select) | 7 years | Same defect coverage, marked products only |
What the DEWALT Warranty Does Not Cover
DEWALT’s published language is explicit about what’s out:
- Excluded Normal wear and tool abuse. Part failure from normal wear (on the 7-year tier) and any tool abuse are excluded — the warranty covers defects, not worn-out tools.
- Excluded Accidental damage, misuse, abuse. Drops, overloads, and misuse are not covered under the 3-year limited warranty.
- Excluded Unauthorized repairs or modifications. If anyone else has repaired or modified the tool, coverage is gone.
- Excluded Accessories. The warranty does not apply to accessories — check accessory-specific terms.
- Excluded Unauthorized sellers. DEWALT can reject claims for products bought from unauthorized sellers, including unauthorized internet sites. Buy from DEWALT or an authorized retailer.
- Excluded Incidental or consequential damages. DEWALT disclaims liability for downstream damages from a tool failure.
How to Register Your DEWALT Tool
- Join MyDEWALT at dewalt.com and create your account.
- Register each tool with its model and serial numbers plus purchase details.
- Keep your receipt — DEWALT may require proof of purchase showing when and where you bought the tool.
- Buy authorized. If you’re unsure a seller is authorized, email [email protected] before you buy.
How to File a DEWALT Warranty Claim
- Confirm the tier: within 90 days (refund), 1 year (free service), or 3/7 years (defect repair).
- For refunds, go to the retailer first; if they refuse, take or send the tool to a factory service center.
- For service/warranty, use ServiceNet on support.dewalt.com to confirm the tool is repairable and find the nearest factory service center.
- Bring proof of purchase and describe the failure — the center diagnoses before quoting.
- Expect inspection charges if the diagnosis finds an excluded cause (abuse, unauthorized repair).
DEWALT Batteries and Chargers: What’s Covered
DEWALT batteries and chargers are covered against defects in materials and workmanship under the same tier structure as the tools. What trips owners up is capacity fade: a battery that holds less charge after hundreds of cycles is experiencing normal wear, not a defect, and isn’t covered.
A battery that arrives dead, won’t charge from day one, or has a failed cell is a defect — document it early and file within the tier windows.
Keep batteries out of extreme heat, don’t leave them fully discharged for months, and keep your receipt — the claim process for batteries is identical to tools: ServiceNet, factory service center, proof of purchase.
Pro tip: photograph the date code on the battery housing when you buy it — DEWALT date codes help establish age if the receipt goes missing, and service centers accept them as supporting proof. If a pack fails just outside a tier window, ask anyway: centers occasionally goodwill borderline cases for registered MyDEWALT members.
DEWALT Warranty vs the Competition
DEWALT’s 3-year term sits in the middle of the pro-tool pack (per each brand’s published terms). Milwaukee advertises 5 years on many tools, Makita matches DEWALT at 3, and RIDGID’s registered Lifetime Service Agreement beats everyone on paper — with a strict 90-day registration catch. DEWALT’s differentiator is the 1-year free service contract covering normal wear parts, which most rivals don’t offer.
| Brand | Standard term | Standout feature |
|---|---|---|
| DEWALT | 3 years (7 on select) | 1-year free service incl. wear parts; 90-day money-back |
| Milwaukee | 5 years (many tools) | Longer base term, no free-service year |
| RIDGID | 3 years + lifetime LSA | Lifetime parts/service/batteries if registered in 90 days |
| Makita | 3 years | Comparable base term |
Match the warranty to your habits: heavy users who maintain their tools should weigh RIDGID’s LSA; everyone else gets excellent, no-fuss protection from the dewalt warranty 3-1-90 bundle and its factory support network.
- Buy from authorized sellers only. A bargain from an unauthorized site can mean zero warranty.
- Use the free service year. Worn brushes and normal-use parts are free in year one — don’t pay for them.
- Keep the receipt forever. DEWALT can require proof of when and where you purchased.
- Don’t open the housing. Unauthorized repair attempts void the remaining coverage.
- Check for the 7-year marking. Some tools carry double the standard term — know which tier you own.
DEWALT Warranty FAQs
How long is the DEWALT warranty?
3 years limited warranty on defects, plus 1-year free service and a 90-day money-back guarantee. Select products carry a 7-year limited warranty instead of 3.
What does the 1-year free service cover?
Maintenance and replacement of parts worn through normal use, free of charge. The service center diagnoses first; excluded causes (abuse, unauthorized repair) may incur charges.
How does the 90-day money-back guarantee work?
If you’re not completely satisfied for any reason, you get a full refund. Start with the retailer; if they refuse, a DEWALT factory service center can handle it. Proof of purchase may be required.
Are DEWALT batteries covered by the warranty?
Batteries follow the tool’s warranty tiers against defects in materials and workmanship, but capacity loss from normal cycling is wear — not a defect. Check your battery’s specific terms.
Does the DEWALT warranty apply if I bought from Amazon or eBay?
Only if the seller is DEWALT-authorized. DEWALT can reject claims for unauthorized sellers, including unauthorized internet sites — verify before you buy.
Which DEWALT tools have the 7-year warranty?
Only products explicitly marked with the 7-year limited warranty. Check the packaging and the product page — it is not automatic across the lineup.
Does DEWALT warranty cover commercial or jobsite use?
The tiers apply to the original end-user purchaser; abuse and misuse are excluded regardless of setting. Heavy jobsite wear beyond defects isn’t covered.
What if I lost my receipt?
DEWALT may require proof of purchase showing when and where you bought the tool. MyDEWALT registration plus retailer order history (for online buys) is your backup.
Are DEWALT accessories covered?
No — the limited warranty does not apply to accessories. Check the accessory’s own terms.
How do I contact DEWALT about a warranty claim?
Call 1-800-433-9258 (7 AM–11 PM ET, 7 days) or use the support form and ServiceNet at support.dewalt.com to find a factory service center.
Conclusion
For most buyers, a dewalt warranty is genuinely strong: 90 days to change your mind, a free-service year that covers normal wear parts, and 3 years of defect protection (7 on marked products). The two claim-killers are unauthorized sellers and unauthorized repairs — avoid both and the process is straightforward.
Register in MyDEWALT, keep the receipt, and use factory service centers. Check your tool’s warranty tier at dewalt.com and confirm the exact terms before you need them.
