Irwin Bi Metal High Speed Hole Saw

The 48mm IRWIN Bi-Metal High Speed Hole Saw is an excellent choice for installing larger ventilation components, substantial waste pipes and oversized electrical accessories. This diameter is particularly valuable in commercial installations where larger service runs are required through walls, floors and ceilings. Engineered with professional-grade bi-metal construction and electron beam welded teeth, this 48mm holesaw delivers consistent cutting performance through repeated use. The sharp, variable tooth design (4-6 pitch) provides efficient material removal with minimal vibration, making it easier to maintain accuracy in demanding applications.
