DeWalt DWE46170 7″ Surface Grinding Dust Shroud

The DeWalt DWE46170 7″ Surface Grinding Dust Shroud is a grinder dust shroud made for dust collection during concrete surface grinding. This is a dust shroud designed for concrete grinding and dust containment. Model Number: DWE46170. It is built for users running 7 inch DEWALT large angle grinders who need a cleaner setup, better visibility at the work surface, and a more practical way to manage fine grinding dust on the job.

What makes this accessory worth paying attention to is how it solves real jobsite problems. The spring-loaded hinged door gives you coverage for open-area grinding, then opens up when you need to work tight to an edge. That matters when you are flattening concrete, cleaning up seams, or getting close to walls without giving up dust collection the whole time.

DEWALT also built the hose connection the way it should have been done years ago. The universal connector locks onto the tool with a twist-and-click connection, which means no duct tape wrapped around the hose just to keep everything together. That saves setup time, holds more securely during use, and makes the whole dust extraction setup less frustrating when you are moving around a slab or repositioning for the next pass.

The body of the shroud is designed to balance durability with enough flexibility to keep contact on the concrete surface. That is important because surface grinding is hard on accessories. A rigid shroud can fight you when the grinder angle changes, while a weak one gets chewed up fast. DEWALT calls out abrasion resistance for abusive jobsite environments, so this is clearly built for real use around concrete dust and debris rather than light-duty shop work.

From a safety and productivity standpoint, the DWE46170 is part of DEWALT’s Perform & Protect approach to dust management. Used with an efficient dust collection vacuum, it helps improve productivity by reducing airborne dust and cutting down on cleanup. It also helps reduce user exposure to harmful silica dust, which is one of the main reasons contractors add a dust shroud to a large angle grinder in the first place.

Compatibility is straightforward. The tool-free clamp system is compatible with all DEWALT large angle grinders, and DEWALT specifically notes it is ideally suited for the DWE4597 and DWE4557. If you are already in that grinder platform, this accessory makes a lot of sense because it adds dust control without complicating your setup.

Who should buy it? Concrete contractors, remodelers, masons, and general tradespeople doing surface prep are the obvious fit. If your work includes grinding floors, smoothing patches, knocking down high spots, or edge work where dust control matters, this accessory earns its keep. If you only grind occasionally outdoors and do not use dust extraction, you may not get the full benefit. But for indoor work, occupied spaces, or code-conscious jobsites, this is the kind of grinder attachment that quickly stops feeling optional.
