The Bosch Progressor range is the go-to bi-metal holesaw for plumbers, electricians and general site work where you're cutting through mixed materials. The 20mm size handles conduit holes, small pipe runs and cable access points in wood, metal, plasterboard and plastics.

Built with an 8% cobalt HSS cutting edge welded to a spring steel body, the Progressor delivers roughly twice the blade life of the previous generation. The progressive tooth design varies the pitch across the cutting edge, which reduces vibration and clears chips faster than a standard tooth pattern.

Features

• 8% cobalt bi-metal construction for cutting wood, metal, plasterboard, plastics and stainless steel
• Progressive tooth strip for faster chip clearance and reduced vibration
• 44mm cutting depth handles standard stud walls and thicker materials
