Hollow masonry drill bit with an SDS Max shank designed to extract dust when used with a dust extractor. Intended to reduce airborne dust during drilling and to speed hole creation and adhesive anchor installation. Compatible with dust extraction systems and compliant with OSHA Table 1 silica control provisions when used with the appropriate extractor/shroud.
Project Ideas
Business
Dustless Anchor Lab
Offer OSHA Table 1–compliant adhesive anchor drilling and installation for hospitals, schools, and clean environments. The hollow SDS Max bit produces clean, dust-free 1-1/2 in anchor holes quickly, improving bond quality and reducing containment costs. Include pull testing and documentation for GC and engineer sign-off.
CleanPass penetrations
Specialize in small-diameter core-alternative penetrations (to 1-1/2 in) through masonry for EV chargers, CCTV, network cabling, and mini-split drains. Market the service as a faster, cleaner option versus wet coring, with integrated dust extraction and optional firestopping and sleeve install.
Retail sign and standoff installs
Provide turnkey facade hardware installs—stand-offs, awnings, and exterior signage—using the 1-1/2 in dust-extracting bit to keep stores open and clean during work. Bundle layout, drilling, adhesive or mechanical anchoring, and weather sealing; sell on minimal dust disruption and neat penetrations.
MicroCore mobile drilling
Operate a per-hole mobile drilling service for trades needing sub-2 in penetrations in tight or sensitive spaces where coring rigs are impractical. Price by depth and material; bring SDS Max hammers, the deep hollow bit, and HEPA extractors to deliver fast, low-mess holes with precise placement.
Heritage-safe retrofit anchors
Serve historic buildings by installing reversible sleeves and adhesive anchors in mortar joints rather than brick faces. The 1-1/2 in hollow bit creates clean, controlled cavities for insert sleeves and stainless hardware, with detailed documentation for preservation boards and minimal dust in occupied spaces.
Creative
StoneLock floating shelves
Drill deep 1-1/2 in sockets into brick or concrete to accept 1-1/4 in steel pipe stubs, epoxy-set for high-load, cantilevered supports. The 39-3/8 in working length lets you create long, parallel sockets for a mantel or floating shelf run, while the hollow bit keeps dust out of living spaces and speeds adhesive anchor prep.
WallBar cantilever bench
Create a modern outdoor bench or bar that projects from a block retaining wall. Use the SDS Max hollow bit to bore clean 1-1/2 in holes for stainless tube arms set with structural adhesive. The integrated dust extraction keeps your patio clean and helps the epoxy bond by removing fines from the hole.
Invisible glow wall-wash
Route 1 in flexible conduit behind a masonry facade for hidden LED wall-wash fixtures. The long, 47-1/4 in bit length allows gentle angles and deep passes through block or stone, and on-tool dust extraction minimizes mess when drilling in finished interiors.
Garden wireways and irrigation sleeves
Drill precise pass-throughs in garden or courtyard walls for low-voltage lighting, drip irrigation, or sensor lines. Line the 1-1/2 in holes with 1-1/4 in PVC sleeves and grommets for a clean, serviceable finish; the hollow bit’s extraction keeps plant beds and pathways free of silica dust.
Rain curtain feature
Lay out a grid of 1-1/2 in through-holes in a masonry screen wall and insert short stainless tubes connected to a concealed manifold to create a sheet-like rain feature. The dust-extracting bit makes indoor manifold tie-ins safer and faster, and the long flute length lets you penetrate thicker walls cleanly.
