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

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.

What makes it special

Engineered for aggressive material removal, these Norton fiber discs tackle rust, scale, and weld beads head-on, exposing clean metal ready for finishing. The center-mount design ensures a secure, stable grip on compatible hubs, reducing wobble and chatter so you can remove material efficiently without compromising control.

Best uses

  • Rust and scale removal on automotive frames, machinery, and structural metal
  • Bead grinding and weld smoothing before priming and painting
  • Rough shaping and deburring of castings and fabricated metal parts
  • Pre-finishing surface prep where quick material removal is critical

Practical tips for optimal performance

  • Match the disc to your tool’s capacity and run it within the tool’s rated speed for safe, effective grinding.
  • Keep the disc flat against the workpiece and use a light to moderate pressure; let the abrasive do the work to avoid gouging.
  • Maintain visibility and control with proper guards and personal protective equipment—eye protection, gloves, and a respirator when removing rust and scale.
  • Inspect discs regularly for cracks or wear; replace when performance drops or you notice vibration.

With a 25-disc pack, Norton’s 4.5 in Aluminum Oxide Center Mount Fiber Discs deliver reliable, consistent cutting performance across multiple heavy-duty projects, making them a dependable choice for metal fabrication, automotive restoration, and DIY metalworking alike.

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.
