Spyder Carbide-tipped Arbored Hole Saw Set (14-Piece) with Hard Case

Spyder's Tungsten Carbide-Tipped (TCT) hole saws cut more materials up to 5x faster and make up to 10x more cuts — lasting longer than conventional bi-metal hole saws. TCT hole saws drill through wood, MDF, fiber cement board, porous concrete block, ceramic wall tile, plastic/PVS and more. 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. All TCT, Tarantula, and Bi-Metal hole saws fit on Spyder Rapid Core Eject arbors and pilot bits (sold separately), and on universal hole saw arbors. Spyder's TCT hole saw is the pro's choice for innovation, high performance, speed, and versatility — drill more holes in more materials in less time. Not for use in hammer mode, or for drilling metal, wood with nails, harder, abrasive materials, or block/brick/tile applications with a Mohs hardness of 6 or greater. Always use a drill with a support handle. 14-piece kit contains (11) hole saws: 1-3/8, 1-1/2, 1-3/4, 2, 2-1/2, 2-3/4, 3, 3-1/2, 4, 4-1/4, 4-1/2; (2) pilot bits: Hex10 TCT, Hex10 HSS; (1) arbor: Hex10 in a hard storage case.
