The Bosch PRO 11 Piece Multi Material PC Plus Hole Saw Set is a professional-grade hole saw kit designed for electricians and plumbers working across a range of interior installation tasks. Rated to last up to 2x longer than a standard HSS M3 hole saw, this set is built around a bi-metal construction with 8% cobalt HSS teeth. The enhanced tooth geometry delivers fast, smooth cuts through challenging materials including steel cladding and drywall, reducing the need to switch between specialist saws on site. The set is compatible with the Bosch Power Change Plus keyless arbor system, which speeds up hole saw changes, pilot drill bit swaps, and plug removal — helping tradespeople maintain pace during cable routing, pipe installation, and recessed lighting work. With eight diameter options ranging from 25mm to 86mm, this kit covers the most common aperture sizes required for back boxes, conduit entry points, and pipework penetrations, making it a practical all-in-one solution for the van.
