Irwin Bi Metal High Speed Hole Saw

The 117mm IRWIN Bi-Metal High Speed Hole Saw is an excellent size for larger industrial installations and commercial construction applications. This diameter is particularly useful for substantial drainage systems, commercial ventilation terminals and various industrial fittings that require generous clearances through structural elements. Built with advanced bi-metal construction and electron beam welded teeth, this 117mm 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 iron and stainless steel.
