Abstract
A cutting tool includes a hole saw, a pilot bit, and an arbor assembly. The arbor assembly includes a shank, a sleeve, a first ball bearing moveable relative to the shank, the first ball bearing engaging the hole saw to releasably secure the hole saw to the shank, and a second ball bearing moveable relative to the shank, the second ball bearing engaging the pilot bit to releasably secure the pilot bit to the shank. The sleeve 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 ball bearing disengages the hole saw, allowing removal of the hole saw from the shank, and to a third position where the second ball bearing disengages the pilot bit, allowing removal of the pilot bit from the shank.
