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.

Core Lifter 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. Only $30 incl GST each core-lifter.png

Core Puller - spring loaded for removing a barrel from the ground, or a core from a barrel. Suits all 1 1/4"UNC and 1/2" BSP barrels. Now in stock - $295 incl GST Core Carrier - available in steel. Handle simply screws into the barrel for carrying larger barrels around with ease. $45 incl GST Each

Slider Core Barrel Quick Release Ring The Slider Core Barrel Quick Release Ring (Second Edition) by SFM Tools in Germany is designed for quick-releasing of core barrels and to protect barrels from jamming on to the core drill shaft. The Slider builds up it's internal stress by approximately 0.3mm expansion between drill shaft and core barrel. This principle ensures the easy release of the core barrel with minimal effort by the operator, preventing jamming core bits on core drills. All the metal parts are made out of special heat treated steel and have permanent lubrication. The fully encapsulated protection is made out of oil-resistant injected rubber, which ensures extremely long life. With an over-all depth of only 10 mm, the Slider can be mounted on any commercial single phase core drilling machine with a standard 1 ¼" UNC connection.
$95 incl GST each

Core Drill sharpening block - made by Tyrolit to resharpen glazed core barrels. The cheapest way to resharpen a barrel is to core into a limestone block but that wears the diamond away also, where as this specialist block removes the bond only. Drill only 3/4 of segment height down, so not to wear weld. Overlap holes, and use both sides and then you will get many resharpens from this. 320mm x 55 x 320mm. Now in stock - $250 incl GST

Drill Guides: Drilling holes in stone tiles or other hard, smooth surfaces is often hard to start, especially when working with the lubricants necessary for diamond hole cutters/drill bits. This drilling guide is designed to hold your bit steady so you can start the hole in the right spot without slipping or sliding. Both use a 120mm suction cup. I have had customers use two of these to make their own seamsetters at a fraction of the normal price.

Plastic (red): 8-80mm, with water injection point (for lubrication when drilling) $15

Steel (blue): 8mm to 54 mm $25

(Pictures show two guides in each photo - prices are for 1 each)
