The Bosch Power Change Plus Arbor features a reinforced shank for improved tolerances, resulting in less play and greater accuracy. It offers better guidance due to the pilot drill bit and a unique keyless system that allows for fast and easy plug ejection with a simple click. This arbor is suitable for use with all corded and cordless drill drivers, providing more robustness and precision than its predecessor. It serves as a keyless connection between power tools and hole saws, simplifying the changing process and saving valuable time.
