Bosch Dust Extraction Bit DXS5044 7/8 Inch SDS-Max Hollow Speed Clean (25 Inch Length 4-Cutter Carbide Head OSHA Silica Concrete Anchor Drill)

Bosch DXS5044 7/8" x 25" SDS-Max Speed Clean Hollow Dust Extraction Concrete Drill Bit

The Bosch DXS5044 7/8-inch SDS-Max Speed Clean hollow dust extraction concrete drill bit bores deep, debris-free anchor holes across cured concrete slabs, structural masonry walls, reinforced foundation footings, and solid brick. Engineered with an internal hollow vacuum channel forged into a 25-inch high-carbon steel body, this 2.9-lb masonry bit extracts pulverized stone dust directly through the bit head during drilling, reducing respirable airborne crystalline silica by up to 90% to meet OSHA Table 1 standards. Featuring an embedded four-cutter solid carbide head and a flexible rubber suction connector, it delivers 25% faster penetration speeds while completely eliminating traditional blow-brush-blow cleaning routines for Simpson Strong-Tie adhesive chemical anchoring systems.

Best Used For:

• Structural Adhesive and Epoxy Anchor Setting: Drilling 7/8-inch holes to spec for Simpson Strong-Tie AT-XP, Set-XP, and commercial chemical resin capsules without manual blowing or wire brushing.
• OSHA Table 1 Silica Compliant Commercial Boring: Drilling deep anchor penetrations inside enclosed facilities, occupied buildings, and cleanroom environments without generating dust clouds.
• Seismic Retrofitting and Rebar Dowel Pinning: Boring 15-inch usable depth channels into reinforced structural concrete foundations while bypassing friction jams around rebar matrices.

Key Performance & Safety Features

• Hollow-Core Internal Extraction Channel: Vacuums concrete dust and stone aggregate directly from the hole bottom during drilling, reducing total anchor prep time by up to 50%.
• OSHA Table 1 Silica Dust Compliance: Captures up to 90% of respirable crystalline silica dust when connected to a certified HEPA dust extraction vacuum system.
• Four-Cutter Solid Carbide Tip Geometry: Micrograin carbide matrix resists rebar strikes, prevents head binding, and drills round holes for maximum adhesive bonding strength.
• 25% Boost in Penetration Speed: Immediate debris clearance eliminates hole friction and thermal buildup, maintaining continuous impact transfer from the rotary hammer.
• High-Carbon Monoblock Steel Body: Forged from premium high-carbon tool steel to provide structural stiffness and resist torsional fatigue across its 25-inch overall length.
• Heavy-Duty Rubber Vacuum Collar: Flexible, airtight rubber extraction collar snaps securely over the bit shank to mate seamlessly with commercial vacuum hoses.

What's Included

Technical Specifications

Pro-Tip: Ensure your HEPA vacuum maintains continuous suction throughout both the downward drilling stroke and the upward withdrawal; keeping airflow active as you pull the bit out guarantees the hole walls remain clean and ready for chemical adhesive injection.
