Dymaxion Vacuum Suction Sets:

The vacuum suction pipe is inserted into the ring take off which then sucks out water or dust into your wet/dry vacuum. The inner reducing rings increase the suction efficiency depending on the core drill bit diameter. These ring sets can be used in conjunction with normal masonry or concrete power drill operations where dust and typical drilling debris cause concern. The master suction ring will grip onto most wall or floor surfaces. The more powerful vacuum you use will increase the overall performance.

Open Ring Diameter: 80mm	Open Ring Diameter: 150mm
Inner Rings: 60, 45 & 40mm	Inner Rings: 115 & 125mm

Dymaxion Vacuums and Base Plates:
- The VACPLATE is a universal device - it has a centre bolt rising from the centre of the plate over which the core drill rig is positioned via the centre U slot that is available on all core drill rig bases, with a large washer (which grips the base) the nut is then tightened down. An example of its use would be a perfect floor (tile/granite) that has to be drilled for a new lavatory bowl - the VACPLATE will not leave a mark on the floor but will hold the rig firmly for drilling.
See our range of vacuum pumps on our separate page here.

The Core Lifter by Golz is a quick easy way for lifting cores out of the hole after drilling. Use the cold chisel to snap the core off (taking care not to damage the holes edge), then use the "lasso" to loop around the core. Use the cold chisel as a handle to lift the barrel out of the ground.
