The Bosch PRO 14 Piece Multi Material PC Plus Hole Saw Set is a professional bi-metal hole saw kit designed to handle the range of materials encountered during interior installation work. Lasting up to 2x longer than a standard HSS M3 hole saw, it is an ideal choice for electricians and plumbers who need a single, reliable solution on site. The set features high-cobalt HSS alloy teeth — incorporating 8% cobalt — for extended cutting life and consistent performance across tough materials including steel cladding and drywall. The enhanced tooth geometry delivers fast, smooth cuts with reduced effort, making it well suited to repetitive tasks such as installing electrical back boxes, pipe runs, and recessed lighting. Compatibility with the Bosch Power Change Plus keyless arbor system means swapping hole saws and pilot drill bits is quick and straightforward, with material plug removal handled efficiently. This reduces downtime between cuts and keeps work moving on busy installations.
