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

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.

About Product Overview

Meet the DeWalt 20V MAX ATOMIC Cordless 4-1/2 in. Angle Grinder (Tool Only) — a compact powerhouse built for fast material removal in tight spaces without the cord clutter. This is the tool you reach for when you need precision, control, and real mobility on install sites, in the shop, or up on scaffolding.

Why this grinder stands out

  • Cordless versatility with 20V MAX power: Move freely between metal, masonry, and other materials without worrying about outlets or extension cords.
  • Brushless reliability: A brushless motor delivers higher efficiency, cooler operation, and longer life for demanding grinding tasks.
  • High-speed performance: Up to 11,000 maximum RPM powers through fast material removal, reducing fatigue during long jobs.
  • Compact, balanced design: A 4-1/2 in wheel diameter and 10.5 in tool length keep it maneuverable in tight spaces, while a weight of just 3.4 lb reduces user fatigue.
  • Quick and secure wheel changes: Spindle lock and a 5/8-11 spindle make swapping wheels smooth and tool-free between tasks.
  • Precise control: Paddle switch offers easy one-handed operation for safer, more controlled grinding and finishing.
  • ATOMIC advantage: Part of DeWalt’s ATOMIC line, designed to deliver aggressive material removal in a compact package for professional results faster.

What you get and how to use it

This tool is listed as a Tool Only model, so you’ll need a compatible 20V MAX battery and charger (not included) to power through projects. It comes with a grinding wheel included so you can start grinding right away, whether you’re deburring a cast-iron edge, smoothing welds, or prepping metal for paint. The grinder is UL Listed for safety and backed by DeWalt’s 3-year limited parts and labor warranty for peace of mind on the job site.

Ideal use cases

  • Metal fabrication: deburring edges, weld prep, rust removal, and surface finishing after cutting.
  • Masonry and tile prep: light grinding and smoothing of mortar joints or tile edges in tight spaces.
  • Facility maintenance: quick cleanup and edge finishing on equipment, supports, and structural components.

Practical tips for getting the most from this grinder

  • Pair with a compatible 20V MAX battery that matches your workload—different amps hours translate to longer runtime between charges.
  • Use the spindle lock for effortless wheel changes and always confirm the wheel is appropriate for the material and inspection criteria you’re meeting.
  • Start with a light touch and steady motion to maintain wheel life and prevent overheating during extended grinding sessions.
  • Ensure you follow safety guidelines and wear appropriate PPE, including eye and hand protection, while operating.

Whether you’re a professional tradesperson upgrading to cordless flexibility or a serious DIYer tackling metal and masonry projects, the DeWalt 20V MAX ATOMIC Cordless 4-1/2 in. Angle Grinder (Tool Only) delivers the performance, portability, and precision you need to finish jobs faster and with confidence.

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 co-op 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.
