A hole-saw device, comprising:
- a motive force;
- a slotted base plate rotatable by the motive force;
- at least one cutting ring;
- locking mechanisms to mount the base plate to the at least one cutting ring;
- and
- the hole-saw device further comprising a first transverse cutter or polisher assembly, which is transverse to a longitudinal direction of the base plate and configured to cut or polish interior to the at least one cutting ring and parallel to a plane of the base plate;
- wherein the first transverse cutter or polisher assembly consists of a single arm hingedly attached to the at least one cutting ring at a first single arm end, the single arm having a cutter or polisher at a second distal single arm end, the single arm actuated to extend towards and retract from a center of the at least one cutting ring by a hydraulic second motive force mounted to the single arm and the at least one cutting ring.
