Dry drilling with extraction vs wet drilling
Water controls dust brilliantly and sabotages your seal.
Wet drilling
Water suppresses dust at source and cools tooling, which is standard for diamond coring and cutting.
It produces slurry, needs management and containment, and is unsuitable in many finished or live interiors.
Dry with extraction
Capture at source keeps the work area dry and is far more practical indoors and on finished surfaces.
It depends entirely on the extractor being adequate and maintained — see extraction setup.
Why it matters for vacuum anchoring
Slurry under a sealing pad is worse than dry dust. If you must work wet, plan the attachment position away from water paths and clean between attachments.
Choosing
Occupied buildings, finished surfaces, fixings: dry with extraction.
Large-diameter coring and hard stone: wet, with the attachment consequences managed.
Questions about this
Which controls dust better?
Both work. Water suppression is highly effective and cools tooling; on-tool extraction keeps the area dry and is far more practical indoors and on finished surfaces.
Why does wet drilling complicate vacuum anchoring?
Slurry under a sealing pad is worse than dry dust. If you must work wet, plan the attachment position away from water paths and clean between attachments.
