Irwin Bi Metal High Speed Hole Saw

The 177mm IRWIN Bi-Metal High Speed Hole Saw is an extended-range size specifically designed for substantial industrial installations. This larger diameter is particularly useful for major commercial ventilation systems, oversized drainage components and various industrial fixtures that demand generous clearances in commercial and industrial environments. Built with advanced bi-metal construction and electron beam welded teeth, this 177mm holesaw maintains sharpness and cutting efficiency through demanding use. The variable tooth design (4-6 pitch) ensures faster cutting action across multiple materials, from softwoods through to harder metals like stainless steel and iron.
