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 1-1/4 in. Bi-Metal General Purpose Oscillating Blade — a compact, durable blade built to tackle a wide range of tasks with your oscillating tool. Its bi-metal construction combines a tough backing with high-speed steel teeth, providing long life and enhanced resistance to tooth wear even when you encounter nails or other hard materials in DIY and professional projects.

What makes this blade stand out

  • Bi-metal engineering: A smart blend of materials delivers durability, flexibility, and longevity, so you can cut through wood, plastic, and soft metals without frequent blade changes.
  • 1-1/4 inch length: A forgiving yet precise size ideal for tight spots, flush cuts, and detailed work in cramped spaces where larger blades can’t reach.
  • General purpose versatility: Designed to handle a variety of tasks from remodeling and cabinetry to crafting projects, making it a reliable all-around blade in your toolkit.
  • Universal fitment: Works with most oscillating tools with standard arbors, giving you a single blade option that covers multiple tool brands and models.

Materials and applications

This blade is purpose-built for versatility. Use it to slice through wood for trim and finishing, cut plastics for clean gaps, and tackle light metals or metal-fastened wood where you might encounter nails or fasteners. The bi-metal teeth stay sharper longer, reducing downtime and helping you maintain momentum on projects that demand steady, controlled cuts.

How to get the best results

  • Match blade speed to material — slower, controlled passes for plastics and metals; steadier strokes for hardwood and trim work.
  • Pace your cuts and let the blade do the work; avoid forcing the tool, which can cause overheating or tooth wear.
  • Keep the work surface steady and use a light guiding hand to maintain straight, clean cuts and minimize tear-out.
  • Inspect the blade periodically for wear and replace when teeth show significant dulling or chipping.

Ideal for

  • DIY enthusiasts and professionals who need a reliable, all-purpose blade for a variety of materials.
  • Projects requiring precise, tight cuts in cabinetry, trim work, or edge work where space is limited.
  • Jobs where you want a single, durable blade that can handle wood, plastic, and light metal without swapping blades constantly.

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.
