Spyder's carbide-tipped Tarantula hole saws cut the toughest materials including steel, stainless steel, nail-embedded wood, fiber cement board, plastics, and more. Durable tungsten carbide cutting teeth make up to 50x more cuts than conventional bi-metal hole saws, and they are up to 10x faster — cutting through the toughest materials and extending bit life. Use with Spyder's Rapid Core Eject arbor system to remove cores without prying (drill hole, press button, pull back the hole saw, and eject the core), cut at an angle, and enlarge existing holes using two adapters on one pilot bit (adapters and pilot bit sold separately). Spyder TCT, Bi-Metal, and Tarantula hole saws fit on Spyder's Rapid Core Eject arbor and pilot bits and on universal hole saw arbors. Using a drill motor with a support handle is recommended. Not for use in hammer mode or on harder, more abrasive materials. 9-piece kit contains (5) hole saws: 1, 1-1/8, 1-3/8, 1-1/2, 2; (2) HSS pilot bits: Hex8, Hex10; and (2) arbors: Hex10 and Hex8, in a hard case.
