75mm HSS bi-metal hole saw with chuck for wood and metal

Bi-metal hole saw material: Heat-treated M42 bi-metal saw blade with a sharp tooth shape, offering durability and good stability. Suitable for processing materials: thin metal, wood, plastic, PVC, etc. The hole saw requires only one pass to cut studs. Ideal for work where high performance and precision are needed. Excellent for cutting wood, plastic, machined metal, nail-embedded wood, plywood, pipes, and steel. High-speed steel hole saw with impact-resistant teeth that resist stripping. The flexible spring steel creates a flexible backing material that allows the hole saw to absorb the impacts of drilling in hard-to-cut materials. Faster, smoother cuts with less vibration than others thanks to its variable-pitch teeth. Creates holes for pipe and tube installations, door lock installations, electrical conduits, flexible hoses, and antennas. The teeth are electron-welded for unbreakable, shock-absorbing alloy bodies. Packaged in individual boxes. Note: The mandrel is included. Product dimensions (L x W x H): 85 x 85 x 50 cm; 300 grams
