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

Extend your drilling reach with the Diablo 5-1/2 in. Hole Saw Extension. This compact accessory adds 5-1/2 inches of depth to your hole saw setup, enabling deeper cutouts in tight spaces without the need to reposition your workpiece.

Key specifications

  • Length: 5-1/2 inches
  • Shank diameter: 7/16 inch
  • Product type: Hole Saw Extension
  • Brand: Diablo
  • Package quantity: 1

Why this Diablo extension stands out

  • Deeper reach for recessed or multi-layer materials, so you can complete complex cuts without changing your setup.
  • Broad compatibility with standard 7/16" shank arbors, making it a versatile addition to many hole saw kits.
  • Simple integration — drop it onto your existing hole saw system and get back to work with minimal downtime.

Use cases

Ideal for electricians routing through walls, plumbers creating through-holes for pipes, or woodworkers needing larger cutouts in furniture or cabinetry where space is limited. The 5-1/2" extension lets you reach deeper into the workpiece, expanding your project possibilities without swapping tools.

Practical tips

  • Pair with a stable drill and maintain steady pressure to minimize wobble when extending the depth of cut.
  • Begin with a light pass to establish a clean guide line, especially when working with harder materials.
  • Keep the work area clear of debris to maintain cutting efficiency and accuracy.
