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

Take on large-diameter holes with confidence using the Irwin 15/16 in. x 6 in. High Speed Steel Drill Bit with a straight 1/2" shank. Built for durability and precision, this bit is ready to tackle metalworking tasks that require a solid, stable cut and reliable performance from start to finish.

  • Material and finish: High Speed Steel (HSS) core with a Black Oxide finish for enhanced lubricity and rust resistance, helping you push through metal films with less heat buildup.
  • Size and geometry: 15/16" drill diameter, 3" flute length, and a total length of 6" provide you with the control and reach needed for deeper holes in metal workpieces.
  • Shank and compatibility: 1/2" straight shank fits a wide range of standard drill chucks, including drill presses and handheld tools, delivering solid grip and stability under load.
  • Packaging and practicality: Sold as a single bit in a protective tube, making storage, transport, and replacement straightforward for both shop benches and field work.
  • Ideal applications: Perfect for drilling larger holes in mild steel, aluminum, and other metals, as well as certain plastics. Use with appropriate cutting fluid or oil to maximize life and cutting speed.

Why this Irwin bit stands out: the combination of a robust HSS core, corrosion-resistant Black Oxide finish, and a generous 6" overall length gives you a dependable, long-lasting tool for demanding metalworking projects. The straight 1/2" shank ensures compatibility with common chucks, providing dependable alignment and reduced wandering on initial entry—crucial when precision matters as you breach through thick materials.

Practical tips for best results: lubricate with cutting fluid when drilling metal, maintain steady feed pressure, and avoid forcing the bit through material to minimize heat. Periodically withdraw the bit to clear chips and inspect the edge for wear. This single Irwin bit is ready to be a reliable workhorse in your toolkit, delivering clean, accurate holes when size and durability matter most.

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.
