Bosch EXPERT Hex Shank Power Change Plus Hole Saw Arbor Extension Bar

Up to 5x faster than a standard adapter, the Bosch EXPERT Hex Shank Power Change Plus Hole Saw Arbor Extension Bar transforms the way professionals work with hole saws. Attaching hole saws to a drill has traditionally been a fiddly, time-consuming process — but Bosch's clever one-click arbor lets you switch hole saws in seconds, with no screws or bolts required.

Simply pull one hole saw out and push another in. Despite this keyless simplicity, the system delivers a firm, reliable connection thanks to a reinforced shank and close-fitting guide drill that actually produces less play than conventional systems. These extension bar arbors are specifically designed for cutting holes in hard-to-reach areas, making them an essential addition to any professional toolkit.

Available in 150mm and 300mm lengths to suit different access requirements, the EXPERT Power Change Plus is compatible with the full range of Bosch Power Change Plus hole saws.
