Abstract: A hole-saw assembly including a hole-saw having at one end a plurality of cutting teeth and at the other end two shafts. The assembly includes a mandrel coaxially aligned with said hole-saw and including a body having two bores therethrough coaxially aligned with said shafts. An annulus located on top of the body is coaxially aligned with said mandrel and hole-saw and includes two holes, the annulus rotatable around its longitudinal axis from a first to a second position. In the first position, the annulus holes are aligned with the bores and shafts allowing the shafts to be freely insertable and removable and in the second position the holes are misaligned to lock the shafts to the annulus. Such an arrangement allows the hole-saw and the mandrel to be easily and quickly mountable and demountable.
