The Irwin BIMETAL hole saw with a diameter of 117 mm is a powerful tool suitable for a variety of materials, including copper, aluminum, iron, plastic, stainless steel, zinc, and wood. Thanks to the innovative WELDTEC™ technology, this hole saw offers a longer lifespan and higher cutting speed, making it ideal for demanding applications. The variable tooth pitch of 4.5 / 5.5 allows for faster cuts and reduces torque build-up, while the thick backing plate provides additional robustness. This bi-metal design ensures high durability and efficiency in chip removal, making work easier and increasing productivity.
