Bosch HCD2051 SDS-Plus Speed Clean 5/16 Inch x 9 Inch Dust Extraction Drill Bit

The Bosch HCD2051 SDS-Plus Speed Clean 5/16-Inch x 9-Inch Dust Extraction Bit operates as a hollow concrete masonry drilling tool engineered to evacuate silica dust through the bit body while boring holes for chemical adhesive anchors and mechanical fasteners. Featuring a solid carbide-tipped two-cutter head, an SDS-plus shank, a 5/16-inch diameter, a 4.25-inch usable length, and a 9-inch overall length, this hollow extraction bit connects to jobsite extractors using the included rubber adapter. By drawing concrete debris through an internal extraction channel during drilling, this tool increases drilling speeds up to 25%, captures 90% of airborne dust, and eliminates manual hole-cleaning steps required for structural epoxies.

Best Used For:

  • Chemical Adhesive & Mechanical Anchor Installation: Boring 5/16-inch holes for concrete screws and post-installed structural anchors while fulfilling clean-hole standards without manual blow-brush cycles.
  • OSHA Table 1 Compliant Concrete Drilling: Capturing 90% of airborne respirable crystalline silica dust directly at the point of impact when connected to a HEPA vacuum extractor.
  • Commercial Masonry & Brick Penetration: Drilling clean 4.25-inch deep penetrations through solid poured concrete, masonry blocks, and brick for electrical and plumbing fixtures.

Key Performance & Safety Features

  • Integrated Hollow Extraction Channel: Internal vacuum passage removes concrete dust instantly at the cutter head, bypassing manual hole cleaning to accelerate anchor installation by 50%.
  • Up to 25% Faster Drilling Speed: Continuous dust extraction eliminates debris accumulation at the cutter tip, reducing thermal friction for rapid penetration.
  • 90% Airborne Silica Dust Reduction: Captures respirable crystalline silica dust directly at the bit head to assist in maintaining OSHA Table 1 jobsite compliance.
  • Solid Carbide Two-Cutter Head: Thermally brazed carbide cutting tip maintains hole diameter accuracy and provides service life comparable to solid drill bits.
  • Adhesive Anchor System Certified: Fulfills strict clean-hole parameters required by commercial structural anchoring epoxies.
  • Includes Speed Clean Vacuum Adapter: Flexible rubber adapter connects the SDS-plus hollow shank directly to standard jobsite extractor hoses.

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: When using the HCD2051 Speed Clean bit for chemical adhesive anchoring, ensure your connected dust extractor maintains an active filter-cleaning pulse mechanism. Uninterrupted airflow ensures the internal extraction core remains clear, allowing you to inject structural epoxy immediately after drilling without manual hole brushing.
