The Bosch EXPERT Hex Shank 8.7mm Power Change Plus Arbor is a professional-grade holesaw arbor designed to dramatically speed up hole saw changes on site. Switching hole saws has traditionally been a time-consuming, fiddly process — particularly when working at pace. This arbor eliminates that frustration with a one-click keyless mechanism that lets you pull one hole saw out and push another in without screws, bolts, or additional tools. Bosch claims it works up to 5x faster than a standard adapter, making it a genuinely practical upgrade for contractors and tradespeople who regularly change between sizes. Despite the simplicity of the quick-change system, the connection remains firm and precise. A reinforced shank transition reduces play compared to conventional arbors, while a rounded shank profile and special reinforcing process help eliminate stress concentrators that cause premature breakage. The arbor also supports fast plug removal — the pilot drill bit can be used to push the cut plug out cleanly. Compatible with the full Bosch Power Change Plus system, this arbor accepts hole saws from 14mm to 210mm, covering a wider range than most alternatives. The 8.7mm hex shank fits standard drill chucks for straightforward fitment across a variety of drills.
