Introduction

Grinding metal, concrete, or stone creates massive amounts of dust — and that dust isn’t just a cleanup hassle. Silica dust, in particular, poses serious health risks. Consequently, if you’re using a grinder without proper dust collection, you’re breathing in harmful particles that can damage your lungs over time.

That’s where the DEWALT DWE46170 7-Inch Surface Grinding Dust Shroud comes in. This shroud is designed to fit your DEWALT grinder and capture dust at the source, keeping your work area cleaner and your lungs safer.
