Abstract
A hole cutting accessory for a power-driven tool may include an arbor that provides for quick release of an annular saw blade component of the accessory, and for quick release of a pilot drill bit component of the accessory. The quick release of the annular saw blade component from the arbor may be accomplished separately from the quick release of the pilot drill bit component from the arbor.

A quick change hole cutting accessory, comprising:
- a hole saw;
- a pilot drill bit;
- and
- an arbor including a shaft configured to be coupled to the hole saw, a bore in the shaft configured to receive the pilot drill bit, at least one actuator coupled to the shaft, and a drive projection coupled to the at least one actuator,
- wherein:
- in a first position of the at least one actuator, the drive projection is coupled to the hole saw, the drive projection transfers a driving force to the hole saw, the pilot drill bit is non-removably coupled to the arbor and the hole saw is non-removably coupled to the arbor;
- and
- in a second position of the at least one actuator that is different from the first position, the drive projection is decoupled from the hole saw and the hole saw is releasable from the arbor;
- and
- in a third position of the at least one actuator that is different from the first position and the second position, the pilot drill bit is releasable from the bore.
A quick change hole cutting accessory, comprising:
- a hole saw;
- a pilot drill bit;
- and
- an arbor including a shaft, a front end portion that includes a bore configured to receive the pilot drill bit and a threaded portion that is configured to be received in a threaded opening in the hole saw, and at least one actuator coupled to the shaft, wherein:
- in a first position of the at least one actuator, the hole saw is non-removably threaded to the front end portion and the hole saw is non-removably coupled to the arbor, and
- in a second position of the at least one actuator that is different from the first position, the hole saw is able to be unthreaded from the front end portion to remove the hole saw from the arbor, and
- in a third position of the at least one actuator that is different from the first position and the second position, the pilot drill bit is releasable from the bore.
A quick change hole cutting accessory, comprising:
- a hole saw;
- a pilot drill bit;
- and
- an arbor including a shaft configured to be coupled to the hole saw, an actuator coupled to the shaft, and a bore configured to receive the pilot drill bit, wherein:
- in a first position of the actuator, the hole saw and the pilot drill bit are non-removably coupled to the arbor;
- in a second position of the actuator that is different from the first position, the pilot drill bit is releasable from the arbor;
- and
- movement of the actuator between the first position and the second position includes a rotational movement of the actuator.
