Bosch 9pc Bi-Metal Holesaw Plumber Set, 19-51mm, Power Change

Bosch 9pc Plumber Holesaw Set

The Bosch Bi-Metal Holesaw Set provides professional-grade cutting performance for high-demand plumbing installations and general construction tasks. This kit features high-speed steel construction alloyed with 8% cobalt for extreme resilience against heat and friction. It covers six essential diameters required for standard pipe passages and plumbing fixtures. The inclusion of the Power Change Plus adapter allows for rapid, tool-free transitions between different sizes on the job site.

Built for the Job

Plumbing contractors utilize this kit for running supply lines, waste pipes, and vent stacks through varied structural materials. The bi-metal teeth are designed to bite through stainless steel, aluminum, wood, and plastics without the immediate dulling associated with standard carbon steel alternatives. Site supervisors value this set for its organized storage case which ensures all components remain secure and accounted for during transport between floors or sites.

• Boring holes for 15mm and 22mm copper pipes using the smaller diameter saws.

• Creating clean penetrations for PVC waste pipes in kitchen and bathroom cabinetry.

• Cutting through metal studs or reinforced flooring for utility routing.

Product Highlights

Advanced Metallurgy

The 8% cobalt alloy maintains tooth sharpness significantly longer than standard bi-metal when cutting tough metals.

Vario-Tooth Geometry

• Alternating tooth pitch reduces vibration during the cut for smoother finishes.
• Optimized chip clearance prevents clogging in deep wood or plastic bores.

Power Change Plus System

This locking mechanism enables the user to swap sizes or eject the core with a single click, eliminating the need for wrenches.
