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 4-1/2" x 1/8" Metal Cutting/Grinding Disc with 5/8"-11 Arbor

Tackle metalwork with confidence using Milwaukee’s proven 4-1/2" metal cutting/grinding disc. Designed for speed and precision, this disc keeps up with demanding cutting and shaping tasks in workshops, fabrication shops, and maintenance bays. With a robust 5/8"-11 arbor and a maximum speed of 13,300 RPM, it delivers consistent performance on metal stock, welds, and structural components.

What’s included

  • Quantity: 1 disc
  • Packaging: Boxed for protection and easy storage
  • Product Type: Metal Cutting/Grinding Disc
  • Brand: Milwaukee
  • Diameter: 4-1/2 inches
  • Arbor Size: 5/8-11

  • Max Speed: 13,300 RPM

Why this Milwaukee disc stands out

  • High-speed efficiency: Optimized to maintain a steady cut and finish at elevated RPMs, helping you complete metalworking tasks faster without sacrificing control.
  • Versatile metal performance: Specifically engineered for cutting and grinding on metal, making it a dependable choice for fabrication, maintenance, and DIY metal projects.
  • Precision with a standard arbor: The 5/8"-11 arbor is a common fit for many 4-1/2" grinders, providing reliable alignment and reduced vibration during use.
  • Broad applicability: Ideal for trimming, deburring, and smoothing edges on metal components, pipes, brackets, and structural pieces.

Use cases and practical tips

Whether you’re shaping a newly cut steel bar, trimming a metal pipe, or cleaning welds, this disc offers consistent results with minimal stock removal waste. For best results:

  • Let the grinder do the work—apply steady, moderate pressure rather than forcing the wheel through the material.
  • Keep a firm, controlled motion to prevent gouging and overheating the disc.
  • Wear appropriate PPE, including eye protection, gloves, and hearing protection, and use a proper guard on your grinder.
  • Inspect the disc for cracks or damage before each use and replace if signs of wear appear.

Built for reliability in metalworking environments, this Milwaukee disc is a practical choice for professionals and serious DIYers who demand consistency, speed, and safety in every cut and grind.

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.
