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.

About Product Overview

Meet the DEWALT Performance Coating 1-1/4 in. W Bi-Metal Oscillating Blade, a purpose-built tool for precise metal cutting with your oscillating multi-tool. The blade combines bi-metal construction with DEWALT's Performance Coating to deliver controlled cuts, reduced heat buildup, and extended life in demanding metalwork tasks.

  • Bi-metal construction pairs a durable cutting edge with a flexible backing to resist breakage and handle tougher metals without chipping.
  • Performance Coating minimizes friction, keeping the blade cooler during long cuts and delivering cleaner edges.
  • 1-1/4 in. width provides a narrower blade profile for accessing tight spaces and intricate metalwork projects.
  • Universal fitment ensures compatibility with most oscillating tools that use standard arbors, so you can swap in this blade across brands.
  • Metal cutting specialization optimized geometry for efficient, steady cuts through metal sheets, channels, brackets, and conduit.

Who should use this blade? Ideal for DIYers and professionals tackling metal remodeling, HVAC work, automotive repairs, or electrical installations where a clean, precise cut matters more than speed. If you’re upgrading from wood-cutting blades or generic blades, this DEWALT blade offers a tangible difference in cut quality and blade life when you’re working with metal.

Practical tips for best results: mount the blade securely on a compatible oscillating tool, apply steady, moderate pressure, and let the tool do the work rather than forcing the blade. For smoother finishes, start with light passes and finish with even strokes across the cut line.

With its robust construction and coating technology, this blade is designed to last longer in metal-cutting tasks, helping you complete projects with fewer blade changes and less downtime.

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.
