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

Engineered for demanding cutting tasks, the DEWALT 1-7/8 in. Bi-Metal Hole Saw is built to deliver reliable, clean holes across a range of materials. With a 1-7/8" diameter and a 1.75" cutting depth, it’s sized for common openings in conduit, piping, and hardware installations, letting you complete through-holes in fewer passes.

Bi-metal construction combines toughness and versatility. The durable body pairs with hardened teeth to resist wear and maintain a steady cut through wood, metal, and certain plastics. This means fewer tool changes, smoother cuts, and extended life on tougher jobs—whether you’re wiring a panel, mounting fixtures, or prepping openings for resistive or conductive fittings.

  • Diameter: 1-7/8" — matches standard hole openings for many fixtures and conduits
  • Cutting depth: 1.75" per pass, enabling efficient through-holes
  • Material: Bi-Metal construction for durability and versatile performance
  • Arbor: Arbor not included; requires a compatible arbor (sold separately)
  • Package: 1 hole saw per package
  • Brand: DeWalt — trusted for professional-grade reliability

Ideal use cases

  • Electrical installations: clean, precise holes for conduit and cable management in panels, boxes, and enclosures
  • Plumbing and HVAC: openings for pipes and fittings through wood, certain metals, and sturdy plastics
  • Carpentry and general fabrication: create reliable pass-throughs for hardware, shelving, and fixtures

Pro tips for best results

  • Secure your workpiece and align the drill to prevent wandering, especially on metal surfaces
  • Use steady feed pressure and let the teeth do the cutting to minimize heat buildup
  • Combine with a compatible arbor and appropriate drill bit to optimize performance and safety

Note: Vendor Internet Sales Policy: Sale of this product on third-party online marketplaces (eg. Amazon, eBay, Walmart) is prohibited.

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.
