A cutting tool includes a hole saw, a pilot bit, and an arbor assembly. The arbor assembly includes a shank, a body, a first engagement member moveable relative to the shank, the first engagement member engaging the hole saw to releasably secure the hole saw to the shank, and a second engagement member moveable relative to the shank, the second engagement member engaging the pilot bit to releasably secure the pilot bit to the shank. The body is moveable to a first position where the hole saw and the pilot bit are secured to the arbor assembly, to a second position where the first engagement member disengages the hole saw, allowing removal of the hole saw from the shank, and to a third position where the second engagement member disengages the pilot bit, allowing removal of the pilot bit from the shank.

A cutting tool comprising:
- a cutting accessory;
- a pilot bit;
- and
- an arbor assembly including
- a shank removably coupled to the cutting accessory and to the pilot bit,
- a body moveable relative to the shank,
- a first engagement member moveable relative to the shank, the first engagement member configured to engage the cutting accessory to releasably couple the cutting accessory to the shank, and
- a second engagement member moveable relative to the shank, the second engagement member configured to engage the pilot bit to releasably couple the pilot bit to the shank,
- wherein the body is moveable between a first position where the first engagement member engages the cutting accessory and the second engagement member engages the pilot bit, securing the cutting accessory and the pilot bit to the arbor assembly, a second position where the first engagement member disengages the cutting accessory, allowing removal of the cutting accessory from the shank, and a third position where the second engagement member disengages the pilot bit, allowing removal of the pilot bit from the shank;
- wherein moving the body from the first position to the second position moves the first engagement member radially inwards towards the shank, wherein radially inward movement of the first engagement member disengages the cutting accessory, and
- wherein moving the body from the second position to the first position moves the first engagement member radially outwards from the shank, wherein the radially outward movement of the first engagement member engages the cutting accessory.
