Irwin Bi Metal High Speed Hole Saw

The 52mm IRWIN Bi-Metal High Speed Hole Saw is specifically sized for certain drainage and ventilation applications where standard 50mm dimensions require additional clearance. This precise diameter accommodates fittings with external sleeves or insulation, making it valuable for specialist plumbing and HVAC installations. Featuring robust bi-metal construction with electron beam welded teeth, this 52mm holesaw provides reliable cutting performance through repeated use. The sharp, variable tooth design (4-6 pitch) delivers efficient material removal with reduced operator effort, producing clean holes whether working with timber joists or metal frameworks.
