For Bosch Progressor holesaws, this Power Change Plus arbor has an beefy 8.7mm hex shank for a secure grip in the chuck of your drill. The arbor fits all sizes of Progressor holesaws. The quick fit/quick release feature means holesaws simply click into the arbor. To change from one size of holesaw to another takes a second or less. No more holesaws jammed or seized on the arbor.
Holesaws are available separately. Supplied with a HSS-G pilot drill.
