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 Bi-Metal Oscillating General Purpose Kit 21 pc — a robust, all-in-one blade kit designed to power your oscillating multitool through a wide range of tasks. Built with bi-metal construction, these blades combine durability with a flexible edge that stands up to frequent cutting across common materials, so you spend less time changing blades and more time getting the job done.

Key advantages that set this kit apart:

  • Bi-Metal durability for longer blade life and reliable performance under everyday cutting loads.
  • 21 pieces in a clamshell for comprehensive general-purpose cutting and organized storage right out of the box.
  • Universal fitment designed to work with most oscillating tools, making swaps quick and hassle-free.
  • Oscillating-tool ready blades optimized for clean, precise cuts with minimal vibration and deflection.

What you can tackle with this versatile set:

  • Woodworking tasks such as trimming and profiling during renovations or cabinet work.
  • Light metal and plastic cutting for DIY projects, repairs, and hobby work.
  • Drywall, plastics, and composite materials where controlled, flush cuts matter.

Who benefits most from this DEWALT kit?

  • DIY homeowners and hobbyists who want a reliable, ready-to-go blade set for a variety of projects.
  • Professional tradespeople who need a dependable general-purpose solution without stocking multiple specialty blades.

Why this kit is a smart choice for your toolbox:

  • Consolidates essential blades into one package, reducing the need to shop for individual blades for different tasks.
  • Bi-metal construction delivers improved wear resistance and longevity compared with standard blades.
  • Universal fit means you can confidently pair these blades with the oscillating tool you already own, keeping workflow smooth on job sites.

Practical tips for best results:

  • Choose the blade that best matches the material and begin with light, steady pressure to avoid blade deflection.
  • Operate at a steady speed and let the blade do the work to minimize heat buildup and extend blade life.
