Irwin Bi Metal High Speed Hole Saw

The 27mm IRWIN Bi-Metal High Speed Hole Saw is particularly useful for larger electrical installations and plumbing work where additional clearance is required. This size is frequently specified for installing larger back boxes, cable entry grommets and medium-bore pipework, making it essential for comprehensive trade toolkits. Engineered with professional-grade bi-metal construction and electron beam welded teeth, this 27mm holesaw provides consistent cutting performance across multiple materials. The sharp, variable tooth design (4-6 pitch) delivers efficient material removal with reduced vibration, producing clean holes in everything from aluminium to zinc.
