Description BAHCO BI-METAL HOLESAW BAHCO® was the first to create a successful bi-metal blade that combines a flexible, shatter-resistant spring steel back with a high speed steel cutting edge to provide faster, more durable cutting power. With the latest generation of bi-metal holesaws, we take the technology even further. The cutting edge (with 4 to 6 teeth per inch) is electron beam-welded to a tough alloy back, and then the teeth are precision ground to further increase cutting efficiency. The result is a holesaw that can cut clean, accurate holes in virtually any machinable material. Vertical slots allow easy core removal.
