Lenox 4-3/4" 121mm Bi Metal Hole Saw is a professional-grade tool designed for cutting through a variety of materials, including wood and metal. It features a vari tooth design, positive rake tooth, and shock-resistant teeth that provide a deep, aggressive cutting action. The speed slot design makes removing the plug faster and easier, while the reinforced backing plate with holes for drive pins resists damage due to high torque. The increased wall thickness improves durability and minimizes tooth loss, while the larger, sharper teeth remove more wood for fast cutting. The optimized tooth design penetrates metal with ease, and the staircase design allows for fast, easy plug ejection. This hole saw offers improved metal cutting performance, easy plug removal, and is 2X more durable and has a 50% longer life than standard hole saws.
