Abstract
A circular saw blade is provided with a first bore of a first size, configured for engagement with a first size arbor. The disk also has a second bore of a second size configured for engagement with a second size arbor. The second bore is disposed concentrically with the first bore, and is placed within a knockout portion of a disk secured to a face of the saw blade. The knockout portion is removable for enlarging an inner transverse dimension of the disk beyond that of the first bore. The second transverse dimension is within an ISO H7 standard tolerance. The disk is thus configured for mounting the second bore on the second size arbor, and alternatively for removing the knockout portion to mount the first bore on the first size arbor.
