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

Milwaukee High Carbon Steel SAE NC Plug Tap and Drill Bit Set — a focused, two‑piece solution built for metalworking precision. Designed for through‑holes and standard coarse threading, this kit delivers reliable performance when you need clean threads quickly and consistently.

Crafted from high carbon steel, this set is optimized for durability and wear resistance in tough metals. The SAE NC (National Coarse) plug tap ensures standard coarse threads that bite fast, making it ideal for rough or freshly drilled holes where speed and reliability matter. The accompanying drill bit pairs with the tap to streamline your workflow, so you can prep and thread in a single, efficient sequence.

  • Two-piece kit with a plug tap and a drill bit, both forged from high carbon steel for lasting wear resistance.
  • SAE NC threading tailored for quick, forgiving coarse threads in metalworking projects.
  • 5.75-inch length provides practical reach for common milling, fabrication, and automotive tasks.
  • Carded packaging offers organized storage and easy on-shelf display.
  • Milwaukee reliability—durable construction and consistent performance trusted by professionals.

Use cases

This set is well suited for automotive repairs, machinery maintenance, fabrication projects, and any metalworking task that requires dependable NC thread tapping. Whether you’re restoring a vehicle, fabricating a new frame, or simply enhancing a metal appliance, this Milwaukee kit helps you complete holes with threaded accuracy in steel and other hard alloys.

How to use

  1. Drill the pilot hole using the included drill bit with appropriate metal cutting lubricant to reduce heat and chip buildup.
  2. Position the plug tap and apply steady, forward pressure to start cutting threads. Maintain a smooth, even rotation to avoid chatter.
  3. Periodically back off to clear chips, then continue tapping to full depth. After threading, remove the tap and deburr the hole if needed.

Tips for best results

Keep the cutting edges sharp and use fresh cutting oil or lubricant designed for steel to extend tool life. Match the drill bit size to your target hole and tap size for the chosen SAE NC thread, and work with steady, controlled feeds to minimize tool wear and maximize thread quality.

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.
