Bi-metal HSS hole saw with 12.5cm shank for wood and metal

The bi-metal hole saw is a heat-treated M42 bi-metal saw blade with a sharp tooth profile, offering durability and good stability. It can cut materials ranging from thin metal to wood, plastic, PVC, and more. The hole saw requires only one pass to cut studs; these hole saws are ideal for jobs where high performance and precision are needed. Excellent for cutting wood, plastic, machined metal, nailed wood, plywood, pipe, and steel. The high-speed steel hole saw blade provides impact- and scratch-resistant teeth. The flexible spring steel creates a material that allows the hole saw to absorb the impacts of drilling holes in difficult-to-cut materials. It cuts faster and smoother with less vibration than other hole saws thanks to its variable tooth pitch. Creates holes for pipe and tube installations, door lock installations, electrical conduits, hoses, and antennas. The teeth are electronically welded to shatterproof, shock-absorbing alloy bodies; packaged in individual boxes. Note: The arbor is included.
