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's High Carbon Steel SAE Straight Taper Tap in 1/8-27 NPT is built for precision threading in metalworking projects where a tight, leak‑resistant pipe thread matters. The high‑carbon steel composition delivers edge retention and durability, while the black oxide finish reduces friction and enhances corrosion resistance for long service life in busy workshop environments.

Designed for internal threading with an SAE straight taper profile, this tap creates true 1/8-27 NPT threads that mate reliably with standard fittings. Its 2.25" overall length provides ample reach for through-holes and many blind-hole applications, giving you versatile performance in a compact tool.

Key Features

  • Material and finish — high‑carbon steel tap with a black oxide finish for wear resistance and smoother cutting.
  • Thread specification — internal 1/8-27 NPT threads, SAE standard, taper cutting for proper engagement with pipe fittings.
  • Size and packaging — 2.25" overall length; sold as a single piece in carded packaging; drill bit not included.
  • Applications — ideal for creating or repairing small-diameter pipe threads in steel, cast iron, and other metals used in housings, manifolds, and equipment.
  • Usage guidance — use with a tap wrench (hand tapping) and appropriate cutting oil; maintain alignment and back off to clear chips for clean threads.
  • Maintenance — clean chips after use, apply light oil, and store in a dry environment to preserve edge and finish.

Why this Milwaukee tap stands out

Milwaukee combines rigid construction with a finish that reduces friction, delivering consistently clean, accurate threads for 1/8-27 NPT ports. This tap is tailored for professionals and serious hobbyists who need reliable results in tight spaces, whether porting hydraulic components, coolant lines, or compact fittings in automotive, industrial, or workshop projects.

Ideal use scenarios

  • Porting small hydraulic manifolds or cylinders that require 1/8-27 NPT threads
  • Adding ports to engine blocks, housings, or machine frames for coolant, oil, or air lines
  • Repairing damaged internal threads in softer metals with proper lubrication for renewed fit and seal
