Abstract
An arbor for a hole saw includes a shaft and a plurality of pins having either bearing surfaces, drive portions or both for engaging the hole saw. The arbor further includes a fixed position flange and a locking plate located above the flange, to which the pins are connected. The saw is mounted to the arbor and has a cylindrical body portion having a closed end defined by a drive plate and an opposite end defining a cutting edge for performing sawing operations on a work piece. The drive plate includes apertures for receiving the drive portions of the pins which pass through holes in the flange. When assembled the drive ends of the pins extend through the holes in the flange and into the mating drive plate apertures such that the bearing surfaces on the pins engage and support the drive plate of the hole saw. The assembly is held together by a locking nut positioned above the locking plate and threaded onto the shaft such that it can be brought into engagement with the locking plate thereby urging and maintaining the bearing surfaces of the pins in engagement with the drive plate.
