The Irwin bi-metal hole saw with a diameter of 20 mm is a powerful tool suitable for a variety of materials, including stainless steel, aluminum, wood, and plastic. Thanks to the innovative WELDTEC™ technology, this hole saw offers a longer lifespan and higher cutting speed. The variable tooth pitch of 4.5 / 5.5 allows for faster cuts and reduces torque buildup, improving efficiency in chip removal. The robust backing plate ensures that the hole saw remains reliable even in the most demanding applications. With its bi-metal construction, it is particularly durable and resilient, making it an ideal choice for professional users.
