Irwin 15 Piece Bi Metal Hole Saw Set

The Irwin 15 Piece Bi-Metal Hole Saw Set is a comprehensive drilling kit designed for cutting precise holes through multiple materials. This professional-grade holesaw set is housed in a durable soft storage case with an unbreakable hinge and internal padding to protect the tools during transport and storage. The case features an integral handle for easy portability on site. Engineered with bi-metal construction, these holesaws deliver exceptional durability when cutting through aluminium, copper, iron, stainless steel, wood and zinc. The precision set teeth enable faster penetration through materials, whilst the electron beam weld creates a stronger bond between the tooth edge and saw body for extended tool life. This makes the set ideal for electricians installing conduit systems, plumbers fitting pipework, and carpenters working with mixed materials. The comprehensive 17-piece kit provides a practical range of cutting diameters to suit common installation tasks. Two mandrels accommodate the full size range, whilst the included pilot drills ensure accurate hole positioning.
