The Bosch EXPERT Power Change Plus Hole Saw Arbor Extension Bar in 300mm is built for professionals who regularly need to cut holes in deep or particularly hard-to-reach areas. The extended 300mm bar provides significantly greater reach compared to the standard length, making it the go-to choice for challenging installations where a shorter arbor simply won't cut it. The same class-leading one-click system means you can still swap hole saws in seconds — no screws or bolts needed — while the reinforced shank and close-fitting guide drill maintain a firm, accurate connection with less play than conventional systems.
