Bosch Concrete Drilling Shroud HDC250 SDSmax Core Bit Dust Collection Attachment (1-1/2 to 6 Inch Diameters Dual Air Chambers Universal Vacuum Mount)

Precision-Engineered Dual Air Chamber Dust Extraction Shroud with Universal Vacuum Surface Clamping and 6-Inch Core Bit Capacity

The Bosch HDC250 SDS-max Core Bit Dust Collection Attachment Universal Concrete Drilling Shroud delivers specialized airborne particulate containment utility and exceptional surface stability efficiency across high-capacity structural coring frameworks. Engineered with a unique dual air chamber system, this high-performance safety shroud utilizes its primary internal chamber to create a vacuum seal directly against rough masonry walls for absolute hands-free tracking stability, while the secondary chamber evacuates concrete dust directly at the rotating bit interface. This contractor-grade diagnostic solution resolves hazardous crystalline silica inhalation exposures, messy jobsite debris cleanup overheads, and complicated tool-specific clipping constraints by decoupling entirely from the rotary hammer and attaching dynamically to structural surfaces. Outfitted with a standard 1-3/8 inch native hose connection port, a replaceable dust-tight sealing brush ring, and an expansive coring width footprint accommodating 1-1/2 inch up to 6-inch diameters, this ruggedized extraction system optimizes subcontractor productivity during commercial plumbing core drillings, structural HVAC duct runs, and industrial electrical conduit penetrations.

Best Used For:

• Commercial Utility Coring: Extracting heavy aggregate particulate matter during high-diameter wall boring for commercial electrical conduit feeds and drain lines.
• HVAC Firewall Penetrations: Maintaining a dust-free enclosed workspace while driving large SDS-max core bits through structural vertical masonry walls and concrete blocks.
• OSHA Silica Mitigation: Serving as a vital field compliance device during plant retrofitting assignments to safely suppress airborne crystalline silica vectors.

Key Performance & Safety Features

• Dual Air Chamber System: Patented airflow division routes strong vacuum pressure to secure the shroud flush against vertical walls while maintaining high dust-capturing velocities.
• Universal Surface Clamping: Surface independent design relies entirely on vacuum suction, making the attachment fully compatible with all rotary hammer brands and layout tools.
• Adaptable Coring Footprint: Optimized to process standard 1-1/2 inch to 5-inch bits natively, expanding to clear large 6-inch diameters by removing the interior ring.
• Replaceable Surface Seal: High-density perimeter brush ring creates a tight barrier matrix against coarse masonry to contain fine floating particles instantly.
• Rugged Suction Gasket: Resilient rubber backing compound conforms dynamically to uneven structural concrete surfaces to prevent loss of seal holding metrics.

Technical Specifications

Pro-Tip: Turn on your dust extractor unit before touching the shroud frame to the concrete wall surface. Allowing the vacuum pressure line to reach max static threshold before alignment guarantees an immediate, rock-solid surface lock that lets you focus both hands safely on managing heavy SDS-max rotary tools.
