Holesaw system

A holesaw arbor comprising:

• a holesaw holder portion coupleable to a holesaw;
• a pilot drill bit holding portion coupleable to a pilot drill bit;
• and
• a decoupling mechanism coupled to the holesaw holder portion and to the pilot bit holder portion,
• wherein the decoupling mechanism is operable in a first mode in which the decoupling mechanism is configured to rotatably drive the holesaw holder portion in unison with the pilot bit holder to form a hole in a workpiece, and in a second mode in which the decoupling mechanism is configured not to drive the holesaw holder portion when the pilot bit holder portion is rotated to remove a plug of material from the holesaw.

A holesaw system comprising:

• a holesaw including a base and a generally cylindrical wall with a proximal end coupled to the base and a distal end with a cutting edge;
• a pilot drill bit including a front cutting tip, a rear shank portion, and an intermediate portion between the front cutting tip and the rear shank portion;
• and
• a decoupling mechanism coupled to the holesaw and to the pilot drill bit, the decoupling mechanism operable in a first mode in which the decoupling mechanism is configured to rotatably drive the holesaw in unison with the pilot drill bit, and in a second mode in which the decoupling mechanism is configured to decouple the holesaw from the pilot bit so that the pilot bit may rotate independently of the holesaw.
