Armeg Professional Diamond Core - 78mm

These dry diamond core bits are of superior design and high quality manufacture. They are suitable for use on lightweight building materials, ordinary facing brickwork and blockwork up to 10N/ sq mm. These cores give rapid, clean service entries with virtually no making good required. The cores thread onto an adaptor, either with a SDS or Hex shank to suit your drill chuck. The adaptor can be fitted with a pilot drill to guide the core. For deep holes, a 200mm extension adaptor is available. For maximum safety and efficiency use a drill of at least 850W with a rigid side handle and fitted with an integral slipping clutch. Cores are only to be used with non-hammer drills or with the impact switched off.
