In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

About Product Overview

DEWALT built this 4-inch angle grinder around a brushless motor, which means less wear on internal parts and more run time per charge compared to a brushed setup - useful when you're working through a stack of cuts or grinding welds on a job site with no outlet nearby. It runs on the 20V MAX platform and hits speeds up to 12,500 RPM, enough for cutting, grinding, and surface prep on metal and masonry.

The spindle lock makes wheel changes fast, and the paddle switch gives you a familiar, secure grip for extended use. At 2.9 lbs tool weight, it's light enough for overhead work or tight spaces without wearing out your arm. This is the ATOMIC sub-brand from DEWALT, aimed at pros who want full-size performance from a compact tool.

Sold as tool only - no battery or charger included - so this is built for anyone already running the DEWALT 20V MAX system. UL Listed for safety, backed by DEWALT's 3-year limited warranty.

  • Brushless motor for extended runtime and durability
  • 20V MAX cordless, up to 12,500 RPM
  • 4-inch wheel diameter, spindle size 3/8-24
  • Tool-only weight: 2.9 lbs; tool length: 10.5 in
  • Spindle lock for quick wheel changes; paddle switch design
  • UL Listed, 3-year limited parts and labor warranty

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
