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

DEWALT 4 in. W Semi-Circle Carbide Grit Grout Blade is purpose-built for grout removal and precise plaster work, delivering aggressive cutting power where it counts. Crafted with carbide grit and a semi-circle profile, this blade slices through hard grout and thin sections with controlled, chip-free results — helping you finish faster with less rework.

Key features that set this blade apart:

  • 4-inch width with a semi-circle cutting edge for accurate, edge-to-edge grout removal in tight tile joints.
  • Carbide grit construction drives durability and long wear, standing up to dense grout and plaster without dulling quickly.
  • Universal fitment designed to work with most oscillating tools, so you can upgrade your grout-removal kit without replacing your entire tool set.
  • Clamshell packaging protects the blade and keeps it ready for fast replacement in busy jobsites.
  • Ideal for grout removal, plaster work, and thin joints — a versatile blade for tile installers, remodelers, and DIY enthusiasts tackling delicate edge work.

Who benefits from this blade

  • Tile installers and remodelers needing clean grout lines without chipping adjacent tiles.
  • DIY homeowners restoring bathrooms, kitchens, or backsplashes where old grout has softened or cracked.
  • Drywall and plaster projects requiring precise, narrow-cut sections along edges and corners.

Use cases and practical tips

  • Target grout lines between ceramic or porcelain tiles for quick, edge-friendly removal. The semi-circle edge helps you follow the grout line without gouging surrounding tile glaze.
  • Resume work where traditional blades struggle — especially in tight joints and around irregular tile layouts.
  • Operate your oscillating tool with steady, low-to-moderate speed and light, gradual passes to maximize blade life and minimize dust.
  • Pair with a dust extraction attachment or vacuum to keep the work area clean and improve visibility during detailing.
  • Protect surrounding materials by starting at the grout line edge and feeding the blade along the line rather than forcing it straight through the joint.

Why this DeWalt blade enhances your project

Choosing a carbide grit grout blade from DeWalt means reliability you can trust on busy job sites. The carbide composition resists wear when chewing through stubborn grout and plaster, reducing blade changes and downtime. The 4-inch width with a semi-circle edge provides precise control, helping you achieve crisper grout lines and cleaner tile edges compared with generic abrasive blades. If you value efficiency, durability, and professional-grade results in ceramic tile maintenance and edge work, this blade is designed to deliver.

Packaging and compatibility details: the blade ships in clamshell packaging and is designed for universal fitment, making it a straightforward upgrade for most oscillating tools you already own. Whether you're refreshing grout in a kitchen backsplash or tidying plaster edges around a shower niche, this blade targets the task with purpose and performance.

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.
