Settle for Nothing Less Than 50% Faster, OSHA-Compliant Dustless Drilling

Streamline your chemical anchoring and structural fastening tasks with the Bosch HCD2051 5/16-Inch x 9-Inch SDS-Plus® Speed Clean™ Dust Extraction Bit. Expertly manufactured from a single piece of premium-grade steel, this hollow core masonry bit features a precision-milled internal dust channel. By connecting directly to a jobsite vacuum system, it dynamically removes concrete debris, stone dust, and fine aggregate powder at the point of impact. This groundbreaking design completely bypasses the labor-intensive, multi-step manual "drill-blow-brush-blow" hole cleaning method, allowing commercial contractors to install post-installed adhesive anchors up to 50% faster while drastically lowering labor costs on high-volume production jobs.

The Bosch Speed Clean extraction system does not just save labor hours; it heavily optimizes drilling physics and operator safety. Removing abrasive powder instantaneously minimizes tip-head friction, yielding up to 25% faster drilling penetration speeds while capturing 90% of airborne masonry dust before it can escape. Solid carbide tips are deeply embedded into a robust two-cutter steel head, providing high impact resistance and a long service lifespan that matches the legendary Bosch Bulldog™ series. An ideal pairing for chemical anchor installation, it is engineered to deliver the pristine hole standards required by structural epoxies. Included with a universal rubber vacuum hose adapter, this bit integrates into the Bosch PRO+GUARD™ solution to reduce hazardous respirable crystalline silica exposure and help your team maintain effortless compliance with OSHA Table 1 safety regulations.

Key Features

  • 50% Time Savings: Bypasses the tedious manual blow-brush cleaning sequence, cutting post-installed anchor setup times straight in half.
  • 25% Faster Concrete Penetration: Continuous core dust collection eliminates friction on the bit tip, allowing you to drive through masonry 25% faster.
  • 90% Airborne Dust Reduction: Dynamically draws fine concrete particles through the hollow steel interior, trapping up to 90% of structural masonry dust.
  • Bulldog-Class Durability: Engineered from a solid one-piece steel body with embedded carbide tips for maximum resilience under heavy trade loads.
  • OSHA Silica Compliance Support: Pairs with industrial HEPA dust extractors via the included rubber adapter to heavily protect workers from respirable crystalline silica dust.

What's Included

  • (1) 5/16" x 4-1/4" x 9" SDS-Plus® Speed Clean™ Dust Extraction Drill Bit
  • (1) Heavy-Duty Speed Clean Rubber Vacuum Hose Adapter

PRO-TIP: Because a 5/16-inch extraction bit has a narrower internal hollow channel compared to large-diameter structural core bits, it can be susceptible to blockages if you encounter trapped moisture or damp concrete dust. To maintain prime extraction velocity, let the vacuum system run for 3 to 5 seconds after pulling the bit completely clear of the hole to ensure the inner core line evacuates entirely!
