A concrete core drill that runs dry: no water core rig, no slurry, no generator. Sept Tools brushless tools cut large-diameter penetrations through reinforced concrete with diamond core bits, at 60 dB and 0.35 m/s2. Designed and built in Roanne, France.
On an occupied site, diamond core drilling of concrete usually means a water-fed core rig: an anchor plate, a hose, a slurry tray, and a wet mess running across the floor below. Sept Tools takes a different route. Our brushless tools handle dry core drilling of concrete and reinforced concrete with diamond core bits, so core drilling concrete no longer requires a thermal or water rig for every large-diameter penetration. The Gazelle Foreuse drives the core bit through dense aggregate and rebar at a constant 1600 W of torque. The Foreuse Périmétrique aligns contiguous bores to open rectangular penetrations without a wet diamond saw. The Pic Épeiche, with its base, holds perpendicularity for certified anchors. All three run at 60 dB, measure 0.35 m/s2 at the handle, and carry an IP65 rating against concrete dust and washdown. Diamond core drilling without the slurry, the noise, or the logistics of a water core rig.
Dry core drilling on occupied sites: none of the noise of a thermal core rig.
Measured at the handle. Full shifts of core drilling concrete without exceeding the limit.
Sealed against concrete dust and washdown, indoors and outdoors.
Brushless motor rated x14 above a carbon-brush tool, up to 20000 h.
Diamond core bits cut concrete and rebar dry. No slurry, no hose, no anchored wet stand for large-diameter penetrations.
The Gazelle Foreuse holds its regime through dense aggregate and reinforcement. Motor life rated x14, up to 20000 h.
The Foreuse Périmétrique aligns contiguous diamond cores to open rectangular penetrations without a wet diamond saw.
Designed and assembled in France. Parts in stock, national service, two-year warranty on every concrete core drill.
Set out the penetration on the reinforced concrete. The Pic Épeiche base or the Foreuse Périmétrique guide holds perpendicularity from the first core.
Start the brushless motor and feed the diamond core bit into the concrete. Constant 1600 W torque drives through dense aggregate without water.
The core bit meets rebar and keeps cutting: no stall, no regime drop. Source extraction to a class H vacuum captures dust at the bit.
Withdraw the intact concrete cylinder. For rectangular openings, the Foreuse Périmétrique repeats contiguous cores to outline the cut.
Combined blowing and extraction leaves a clean dry bore, ready for a duct, a riser, or a certified chemical anchor.

A wet core rig needs an anchored stand, a water feed, a slurry tray, and runoff protection on every penetration.
Dry core drilling of concrete: the Gazelle Foreuse cuts with a diamond core bit and no water, removing the slurry chain entirely.
Underpowered or battery tools lose torque when the core bit reaches rebar, forcing the operator to push.
Brushless 1600 W constant torque: the diamond core bit crosses reinforcement without a drop in regime.
Thermal core rigs run at high noise levels: time restrictions, neighbour complaints, lost contracts on sensitive sites.
60 dB brushless: core drilling concrete on occupied sites with no scheduling restriction.
Cutting an opening with a water-fed diamond saw means slurry, hose logistics, and a heavy setup on an occupied building.
The Foreuse Périmétrique drills contiguous dry diamond cores to outline the opening: clean, dry, no boue.
Dry core drilling without extraction releases concrete and silica dust into an occupied space.
Direct connection to a Sept Tools class H vacuum: source extraction at the bit keeps the bore and the air clean.
Large-diameter diamond core drilling of concrete walls and slabs for HVAC ducts, plumbing risers, and cable trays. The Gazelle Foreuse drives the core bit through dense aggregate and rebar at constant torque, dry, so the penetration is clean and ready without a slurry cleanup pass.
The Foreuse Périmétrique aligns a row of contiguous diamond cores to outline a rectangular opening for a hatch, a riser, or a technical passage. Dry core drilling replaces the water-fed diamond saw: no boue, no hose logistics, no neighbour complaints on an occupied building.
The Pic Épeiche on its base holds perpendicularity and depth for chemical anchors that must satisfy a technical assessment. The hole connects to a class H vacuum for combined blowing and extraction, so the bore is clean and ready to receive the resin without a separate compressor.
Diamond core bits extract an intact cylinder for geotechnical study, quality control, or pathology expertise. Constant brushless torque crosses reinforcement without shattering the periphery, so the core drilling concrete sample reaches the lab intact and usable.
