Dry Diamond Cores

Dry diamond cores for drilling into hard materials such as concrete blocks, brick, paving slabs, asphalt, limestone, clay, bricks and cured concrete. Simple to use, they produce very clean-cut holes. In use the cores are threaded onto an adaptor, either with a SDS or Hex shank to suit the drill chuck. The adaptor can be fitted with a pilot drill to initially guide the core. For deep holes a 200mm extension adaptor is available. Note; the 22mm core is 300mm long, and does not require a pilot drill. For maximum safety and efficiency use a drill of at least 850W with a rigid side handle and fitted with an integral safety clutch. Cores should only be used with non-hammer drills or with the impact switched off.
