Ring-saw assemblies and processes

A hole-saw device, comprising:

• a motive force;
• a base plate rotatable by the motive force;
• at least one cutter;
• and
• locking mechanisms to mount the base plate to the at least one cutter;
• wherein the base plate is a slotted platter, the slotted platter having a plurality of slots radiating outwardly from a slotted platter center;
• wherein the locking mechanisms to mount the slotted platter to the at least one cutter comprise locking pin clips slidably mountable to the slotted platter along the plurality of slots;
• wherein the at least one cutter has a plurality of tabs configured extend through the plurality of slots, the plurality of tabs having a notched recess to connect the at least one cutter onto the platter by an edge of the locking pin clips;
• and
• wherein the at least one cutter is configured to be lockably retained to the platter by sliding, then securing, the locking pin clips towards the slotted platter center until the locking pin clip edge extends into the notched recess, whereby the at least one cutter is are retained thereon;
• wherein each at least one cutter comprises an assembly having a cylindrical extension mountable to the slotted platter on a first end;
• a cutting ring mount to mount a cutting ring along an entire circumference of the cylindrical extension on a second end;
• wherein the cutting ring mount comprises a plurality of tabs configured to slidably extend into corresponding slots on the second end of the cylindrical extension, the corresponding slots having a recessed portion at its distal end to receive a rotatable locking disk disposed at a distal end of the plurality of tabs;
• wherein the rotatable locking disk has a first position to allow entry of the plurality of tabs into the corresponding slots and the rotatable locking disk rotatable into a second position into the recessed portion of the corresponding slots;
• and
• wherein the locking disk has a rotational axis that is perpendicular to a longitudinal axis of the hole saw.
