FIELD: processing of materials by cutting.
SUBSTANCE: invention can be used for making round holes in walls, ceilings or similar structures made of concrete or other mineral materials. Core bit crown comprises tubular rod, mounting platform, located at near end of tubular rod and intended for installation of core bit crown on power tool. Ring cutting section of the bit includes abrasive cutting segments located at the far end of the tubular rod. First transceiver is located at the far end of the tubular rod. Provided is a repeater comprising a second transceiver at the near end of the tubular rod, antenna facing first transceiver and wire connection between said antenna and follower.
EFFECT: efficient destruction of material due to abrasion of ring-shaped hole with intact inner cylindrical core, increased stability of crown.
