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 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.
