'Oops' Arbor

'Oops' Arbor

The 'Oops' arbor is for use in conjunction with the A1, A2 and A10 hole saw arbors. Replacing the pilot drill, the 'Oops' arbor enables diameters to be enlarged by attaching a saw of the same size to that of the existing hole, thereby acting as a pilot for the larger diameter saw. Minimum hole enlargement is 4.7mm between the pilot saw diameter and the cutting saw diameter.
