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

Introducing the DEWALT 4 in. Bi-Metal Hole Saw—a durable, professional-grade tool crafted to deliver clean, precise cuts across metal, wood, and composites. Designed for serious projects, this 4-inch hole saw stands up to demanding use while maintaining accuracy and efficiency.

  • Bi-metal construction combines high-strength teeth with a flexible alloy body for long life, reduced tooth wear, and dependable performance through tough drilling tasks.
  • 4" diameter with a 1.75" cutting depth enables fast, substantial openings for electrical conduits, plumbing, vents, and larger hardware installations.
  • Arbor not included—intended to pair with your preferred arbor or quick-change system. Check your toolkit for a compatible setup to match your drilling workflow.
  • Trusted DeWalt quality meaning reliable cutting accuracy, consistent results, and the resilience required on professional jobsites.

Ideal use scenarios:

  • Electric, HVAC, and plumbing installations requiring clean 4" holes in metal panels or wood structures.
  • Woodworking projects where you need a precise, large-diameter opening without excessive splintering.
  • Home improvement tasks like venting, exhaust routing, or large-pass-through installations.

Tips for best results:

  • Begin with a sharp pilot hole to guide the saw and reduce wandering.
  • Apply steady pressure and use lubrication when cutting metal to minimize heat buildup and extend blade life.
  • Secure the workpiece and drill at a controlled pace to maintain a clean, square hole.
  • Pair with a compatible arbor and a drill/driver that can handle the torque required for smooth cuts.

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.
