Bahco Bi-Metal Hole Saw
From the Manufacturer BAHCO was the first to create a successful bi-metal blade that combined a flexible, shatter-resistance spring steel back with high speed steel cutting edge that provides faster, more durable cutting power. With the latest generation of bi-metal holesaws, we take the technology even further. The cutting edge (eith 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. Knockout holes allow easy core removal. 5 1/4 Diameter 133mm high speed cutting edge Flexible Shatter-resistant spring steel back high speed cutting edge
