Bosch Grinder Dust Shroud GA50UC 5 Inch Cutting Guard (Single Screw Depth Stop Airsweep Vacuum Port Footplate Masonry Mortar Silica Hood Cover)

Bosch GA50UC 5" Angle Grinder Dust Collection Cutting Attachment

The Bosch GA50UC 5-inch dust collection cutting guard converts compatible small angle grinders into clean, stabilized concrete scoring and mortar tuckpointing machines while capturing up to 99% of airborne crystalline silica dust at the point of contact. Built with a 1.2-lb hybrid composite and steel housing, this extraction hood features a broad, durable metal footplate that glides smoothly across masonry to prevent kerf wobble and uneven blade gouging. Outfitted with a rapid single-screw depth adjustment mechanism, a tool-free grinder clamp assembly, and an adapter-free Airsweep vacuum extraction port, it provides precise cutting control, cleaner air quality, and strict OSHA Table 1 compliance across indoor renovations, tile work, and commercial masonry restoration.

Best Used For:

• Mortar Joint Raking and Tuckpointing: Guiding 4-1/2-inch and 5-inch diamond tuckpoint wheels cleanly along brick mortar joints while extracting silica dust before it escapes.
• Indoor Concrete Slab Scoring and Trenching: Slicing straight floor relief lines and shallow plumbing chases inside occupied residential or commercial buildings.
• Masonry Paver and Backer Board Sizing: Trimming concrete pavers, porcelain tile, and cement backer board cleanly with precise, repeatable single-screw depth settings.

Key Performance & Safety Features

• Near-Total Dust Containment: Traps up to 99% of airborne concrete and silica particles at the blade edge to ensure cleaner jobsite air and faster final cleanup.
• Airsweep Direct Vacuum Port: Connects directly onto Bosch Airsweep vacuum extractors and standard 35mm industrial hoses without needing loose aftermarket adapters.
• Tool-Free Grinder Mounting: Quick-clamp installation system locks securely onto compatible grinder collars in seconds without hand tools.
• Precision Single-Screw Depth Control: Dedicated thumb screw allows operators to set, calibrate, and maintain uniform cutting depths across long linear passes.
• Large Structural Footplate: Broad metal base stabilizes the tool flat against the substrate to eliminate blade chatter, tilting, and crooked cuts.
• Compact Low-Profile Design: Lightweight 1.2-lb footprint delivers superior balance and unobstructed sightlines when cutting along vertical walls and tight corners.

Technical Specifications

Pro-Tip: Pull the grinder along the cut line in a backward dragging motion rather than pushing it forward; dragging keeps the metal footplate seated flat against the brick face and channels cutting debris directly into the Airsweep suction stream.
