Abstract
An arbor for a hole saw includes an arbor shaft configured to be coupled to a power tool. The arbor shaft defines a longitudinal axis. The arbor also includes an arbor stem supported by the arbor shaft. The arbor stem includes at least one arm having a threaded portion configured to engage the hole saw. The arbor further includes an actuator supported by the arbor shaft. The actuator is operable to move the threaded portion of the at least one arm relative to the longitudinal axis.
Claims20
An arbor for a hole saw, the arbor comprising:
- an arbor shaft configured to be coupled to a power tool, the arbor shaft defining a longitudinal axis;
- an arbor stem supported by the arbor shaft, the arbor stem including at least one arm having a threaded portion configured to engage the hole saw;
- and
- an actuator supported by the arbor shaft,
- wherein the actuator is operable to move the threaded portion of the at least one arm relative to the longitudinal axis.
A method of operating an arbor for a hole saw, the arbor including an arbor shaft configured to be coupled to a power tool, the arbor shaft defining a longitudinal axis, an arbor stem supported by the arbor shaft, the arbor stem including at least one arm having a threaded portion configured to engage the hole saw, and an actuator supported by the arbor shaft, the method comprising:
- threading the hole saw onto the threaded portion of the at least one arm;
- actuating the actuator;
- and
- moving the threaded portion of the at least one arm relative to the longitudinal axis in response to actuating the actuator to release the hole saw from the threaded portion of the at least one arm.
An arbor for a hole saw, the arbor comprising:
- an arbor shaft configured to be coupled to a power tool, the arbor shaft defining a longitudinal axis;
- an arbor stem supported by the arbor shaft, the arbor stem including a plurality of arms, each arm having
- a threaded portion configured to engage the hole saw,
- a base portion extending from the threaded portion, and
- a hole defined by the base portion;
- a collar supported by and slidable along the arbor shaft;
- a plurality of pins extending from the collar toward the base portions of the plurality of arms, a portion of each pin receivable within the hole of a respective arm;
- and
- a biasing member coupled to the plurality of arms,
- wherein the collar is movable relative to the arbor shaft between a first position, in which the plurality of pins is received in the holes of the plurality of arms to maintain the threaded portions of the plurality of arms away from the longitudinal axis to engage the hole saw, and a second position, in which the plurality of pins are moved at least partially out of the holes of the plurality of arms such that the biasing member moves the threaded portions of the plurality of arms toward the longitudinal axis to release the hole saw.
