About this product
This 121mm bi-metal holesaw from Faithfull is designed for large-scale cutting tasks such as major ducting installations, large-diameter waste pipes, and access points through timber or metal frameworks. It suits professional plumbing, construction, and ventilation work where a wide cutting diameter is needed.
Made from bi-metal with 8% cobalt content, it offers good heat and wear resistance for extended product life. The precision-set teeth allow aggressive material penetration with efficient swarf clearance, giving a smooth and fast cutting action across thin and thick gauge materials.
It cuts stainless steel, steel, aluminium, sheet metal, mild metal, non-ferrous metals, cast iron, soft and hard woods, and PVC, and is suitable for use in most variable speed power drills. Cutting depth is 38mm.
