  • PC850 percussion cores are an innovative new dry diamond core that makes drilling large diameter holes in all types of masonry quicker and easier. An essential addition for electricians and plumbers or anyone involved in the installation of piping and ventilation systems.
  • Until now, dry diamond core drilling has only been possible with drilling machines operating on rotary. Marcrist PC850 Dry Diamond percussion core users are able to maintain an uninterrupted percussion action through both pilot hole and diamond drill phases, resulting in faster, easier drilling of large diameter holes in all types of masonry materials.
  • PC850 Dry Diamond percussion cores will work on most manufacturers’ percussion drilling machines, and have been launched in conjunction with the new Marcrist DDM1 compact lightweight diamond drilling machine.
  • The new diamond segment has a turbo formation for increased drilling speed which, when combined with the percussion action, provides unbeatable speeds through masonry materials.
  • PC850 Dry Diamond percussion cores not only provide exceptional diamond drilling speed but also life. In tests, the new diamond percussion core has achieved up to 300 holes on general building materials.
  • PC850 cores also minimises the amount of break-through at the rear side of the material. This is because it is the diamond segments rather than the impacting action that are doing most of the work, resulting in a cleaner, neater exit.
