The Bosch EXPERT SDS Plus Power Change Plus Arbor is a professional-grade holesaw arbor designed to eliminate the time-consuming process of swapping hole saws during drilling tasks. Changing hole saws on a traditional arbor means fumbling with screws and bolts, costing tradespeople valuable time on site. The Power Change Plus uses a one-click keyless mechanism that lets you pull out one hole saw and push in another in seconds — up to 5x faster than a standard adapter. Despite the simplicity of the system, connection quality is not compromised. The reinforced shank transition reduces play compared to conventional arbors, while the rounded shank and special reinforcing process help eliminate stress concentrators that can cause premature breakage. The arbor accepts the full range of Bosch Power Change Plus hole saws from 14mm to 210mm, making it suitable for electricians, plumbers, and joiners working across a wide variety of applications. The pilot drill bit also doubles as a plug ejector, pushing cut plugs out quickly and cleanly for uninterrupted workflow.
