The Bosch EXPERT Hex Shank Power Change Plus Arbor is a professional holesaw arbor designed for rapid, tool-free hole saw changes on the job. Fitting and removing hole saws has traditionally been a time-consuming process that costs tradespeople valuable time on site. The EXPERT Power Change Plus addresses this directly, delivering up to 5x faster accessory changes compared to a standard adapter — all without screws, bolts, or keys. The one-click keyless system lets you pull one hole saw out and push another in within seconds. Despite this convenience, the reinforced shank transition provides a firm, low-play connection that outperforms many conventional systems, reducing the risk of premature breakage during demanding work. Compatible with the full range of Bosch Power Change Plus hole saws from 14mm to 210mm, this arbor suits electricians, plumbers, and general contractors who regularly switch between hole saw sizes. It also features a smooth plug-ejection function, allowing the pilot drill to push out cut plugs quickly and cleanly.
