Bosch Dust Extraction Bit DXS5050 1 Inch SDS-Max Hollow Speed Clean (8 Inch Depth 4-Cutter Carbide Head OSHA Silica Adhesive Concrete Drilling)

Bosch DXS5050 1" x 8" SDS-Max Speed Clean Hollow Dust Extraction Concrete Drill Bit

The Bosch DXS5050 1-inch SDS-Max Speed Clean hollow dust extraction masonry drill bit bores clean, debris-free holes in cured concrete, reinforced aggregate, stone, and solid masonry for structural chemical adhesive anchors. Engineered with an internal hollow vacuum channel forged into a one-piece alloy steel shaft, this 17-inch drill bit extracts airborne particulate matter directly through the bit head during drilling, reducing respirable silica by over 90% and satisfying OSHA Table 1 safety compliance. Featuring a four-cutter embedded solid carbide tip matrix and an included replaceable rubber vacuum hose adapter, it delivers 25% faster drilling rates while completely eliminating the traditional blow-brush-blow hole cleaning sequence for structural epoxy and hybrid adhesive anchor installations.

Best Used For:

• Structural Chemical Adhesive Anchor Setting: Drilling clean 1-inch anchor holes for Simpson Strong-Tie AT-XP, SET-XP, and epoxy anchoring systems without separate manual hole-cleaning steps.
• OSHA Silica Table 1 Compliant Commercial Drilling: Boring concrete anchor holes in occupied spaces, indoor retrofits, and high-rise commercial structures without generating airborne silica plumes.
• Rebar Down-Dowel and Post-Tensioned Retrofits: Drilling deeply into high-PSI cured slab foundations and retaining walls while preventing cutter binding around embedded rebar.

Key Performance & Safety Features

• Hollow-Core Vacuum Channel: Extracts concrete dust and stone aggregate directly from the hole bottom during drilling, cutting overall anchor installation labor time by 50%.
• OSHA Table 1 Dust Compliance: Captures up to 90% of respirable crystalline silica dust when connected to an approved HEPA dust extractor system.
• 4-Cutter Solid Carbide Head: Embedded micrograin carbide cutting tips resist rebar strikes, prevent bit binding, and produce round anchor holes for maximum epoxy bond strength.
• 25% Faster Penetration Velocity: Immediate particulate removal eliminates friction and thermal build-up inside the hole, ensuring maximum rotary hammer impact transfer.
• Monoblock Alloy Steel Forging: Machined from a single block of premium tool steel to deliver exceptional torsional durability under continuous heavy-duty hammer drilling cycles.
• Replaceable Rubber Vacuum Collar: Heavy-duty, flexible suction adapter snaps securely onto the bit shank and seals tightly around standard dust extractor hoses.

• (1) Replaceable Heavy-Duty Rubber Vacuum Hose Extraction Collar Adapter

Technical Specifications

Pro-Tip: Keep your dust extractor running during the entire drilling stroke; this clears concrete pulverized aggregate continuously through the hollow center and produces an adhesive-ready anchor hole immediately without requiring wire brushing or compressed air blowouts.
