*KEY: T = Threaded, LH = Pin Locating Holes added and central thread drilled out**, ED = Extended Depth** Due to the nature of all holesaws, the threads are not always sufficiently strong to hold securely to the arbour. For this reason, for certain holesaw sizes, the threads are drilled out and 2x locating holes added that then form the method of drive from the corresponding pins on the tap.
