High-speed steel HSS bi-metal hole saw with shank for wood and metal, drilling panels, plastic (28MM+30MM+32MM+35MM+38MM+40MM)

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 be used to 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 flexible material that allows the hole saw to absorb the impacts of drilling holes in hard-to-cut materials. It cuts faster and smoother with less vibration than other hole saws thanks to its variable-pitch teeth; it creates holes for pipe and tube installations, door lock installations, electrical conduits, hoses, and antennas. The teeth are electronically welded for a strong core. Made of shatter-resistant, shock-absorbing alloy; packaged in individual boxes. Specification: Material: M42 HSS steel.
