Long and short Core Barrels

Standard barrels are 450mm long.
Longer core barrels are regularly needed in some applications, whereas shorter barrels work well in confined spaces.

Most have to come from the Eastern states, but here are the barrels we keep in Bibra Lake, W.A.
They will core concrete as well as reinforced concrete.

See our "Core Drill Accessories and Spare Parts" page for further info here.

Note - For operator safety, most manufacturers recommend drilling over 67mm be done with the drill mounted in a stand.
If in doubt, contact us,  the barrel or drill manufacturers.

Dymaxion diamond core bits are laser welded and 220mm long.
Suitable for cutting concrete, brick, compressed fibre cement sheet, granite and other masonry building materials. 
Can be used on core drills or standard drills (SDS Plus, Max or hex) with an adaptor.
Back end fitting is 1/2" BSP female.
Can be used with a pilot bit (ABD300) on larger diameters to prevent drifting when starting.
Maximum coring depth 190mm

  • Diamond core drills and hole saws require the use of proper lubrication, correct drill speed and proper pressure.
  • Drilling methods and techniques vary significantly depending upon the material being drilled.
  • To achieve optimum cutting performance and maximum core drill life use a slow to very slow drill speed, low drill pressure, and plenty of water for lubrication. Quench with water if no water feed on your drill.
  • Variable speed drills work best since the correct speed can be selected. Lower speeds work best.
  • The life of any type of diamond drill depends upon the hardness, abrasiveness and thickness of the material being drilled and the specific drilling techniques used.
  • Do not use hammer mode
  • Withdraw regularly from hole to clear debris, otherwise bit can jam
  • Do not force.
  • Wall ties and any loose obstructions can damage the bits.
  • If using standard drill, ensure your drill has a safety clutch and variable speed.
  • Ensure drill has sufficient power to use larger diameters.

Silica dust - when workers cut, saw, crush, drill, grind or polish products that contain silica, particles are created, which are one-hundredth of the size of a grain of sand. These can get  stuck deep in the lungs. 
Ensure precautions to limit exposure to dust are in place.
See the WA government's info on silica dust here.
