The Bosch EXPERT Power Change Plus Arbor and HSS-G Pilot Drill is a keyless hole saw arbor system designed to dramatically speed up hole saw changes for tradespeople working on demanding applications. Changing hole saws with a conventional arbor is a time-consuming process that costs professionals valuable time on site. The EXPERT Power Change Plus eliminates this frustration entirely with a one-click mechanism — simply pull one hole saw out and push the next one in, with no screws or bolts required. Despite the speed of the system, there is no compromise on rigidity or accuracy. A reinforced shank transition and close-fitting pilot drill reduce play to less than that found in many traditional screw-fix systems, making it suitable for precise work across a range of materials. The arbor accepts hole saws from 14mm up to 210mm, covering the full range of Bosch Power Change Plus compatible hole saws. The HSS-G pilot drill is also designed to assist with plug removal, helping to push cut plugs clear quickly and smoothly once a hole is complete.
