Bosch Dust Extraction Guard 19DC-9 9 Inch Angle Grinder (Depth Adjustment OSHA Silica Compliance Support Metal Housing Concrete Cutting Attachment)

Bosch 19DC-9 9-Inch Angle Grinder Dust-Extraction Guard

The Bosch 19DC-9 Dust-Extraction Guard is an industrial masonry cutting attachment engineered for concrete slab scoring, expansion joint routing, brick wall scoring, and stone slab trimming using 9-inch angle grinders. Designed to connect 9-inch diamond cutoff wheels directly to 35 mm vacuum extractor hoses, this metal shroud supports OSHA Table 1 silica dust compliance when integrated into the Bosch PRO+GUARD dust collection system. Equipped with a single-screw depth adjustment mechanism, a wide steel foot plate for cutting stability, and heavy-gauge metal construction, this 5-pound shroud fits 1800-series, 1900-series, 1893-6, and 1994-6 angle grinders.

Best Used For:

• Concrete Slab Expansion Joint Cutting: Routing straight expansion joints in cured concrete slabs while capturing airborne crystalline silica dust.
• Brick Masonry & Block Wall Scoring: Trimming structural brickwork and cinder blocks cleanly without blanketing jobsite interiors in mortar dust.
• Stone & Paver Tile Slicing: Guiding straight-line plunge cuts across thick stone pavers and concrete retaining wall blocks.

Key Performance & Safety Features

• OSHA Silica Table 1 Compliance Support: Captures harmful crystalline silica dust at the point of cut when hooked to an OSHA-compliant HEPA vacuum.
• Heavy-Gauge All-Metal Housing Construction: Rugged steel casing withstands continuous impact from abrasive concrete slurry and high-speed debris.
• Single-Screw Depth Adjustment Mechanism: Allows operators to set exact blade cutting depths quickly and maintain uniform groove depths.
• Broad Steel Guide Foot Plate: Wide base plate stabilizes the 9-inch grinder to prevent wheel binding and keep cuts square.
• Direct 35 mm Vacuum Port Connection: Mates directly to 35 mm anti-static vacuum hoses and Bosch VAC-series dust extractors without loose adapters.
• Type 1 / 1A Wheel Guard Compatibility: Accommodates standard 9-inch diamond cutoff wheels and masonry abrasive discs.

Technical Specifications

Pro-Tip: Set the single-screw depth guide to allow the diamond blade to extend 1/4 inch past the bottom of the concrete slab before cutting; keeping the foot plate firmly flush against the surface maintains maximum vacuum suction.
