Spyder hole saws are the pro's choice for innovation, high performance, speed, and versatility – drill more holes in more materials in less time, cutting up to 5x faster than conventional hole saws. Use Spyder's Rapid Core Eject™ arbor system to remove cores without prying (drill the hole, press the button, pull back the hole saw, and eject the core), cut at an angle, and use two adapters on one pilot bit to enlarge existing holes.
Spyder hole saws fit on Spyder's Rapid Core Eject™ arbors and pilot bits (sold separately) and on the universal hole saw arbors (1/2-20 thread hole saws use Spyder Hex8 arbor/pilot bits and 5/8-18 thread hole saws use Spyder Hex10 arbor/pilot bits). It is recommended to use a drill motor with a support handle. Bi-Metal hole saws feature variable tooth pitch geometry that yields fast, clean cuts through steel, stainless steel, aluminum, nail-embedded wood, non-ferrous metal, plastics/PVC, and more (maximum cutting depth: 1-7/8-in). 13-piece kit includes: 9 holes saw bits (3/4, 7/8, 1-1/8, 1-3/8, 1-1/2, 2, 2-1/8, 2-1/4, and 2-1/2), 2 High-Speed Steel (HSS) pilot bits (Hex 8 and Hex 10) and two arbor adapters (Hex 8 and Hex 10) in a hard storage case. Spyder's Tungsten Carbide Tipped (TCT) hole saws last longer, cut cleaner, and drill into more materials, including wood, MDF, plywood, cement fiber board, porous concrete block, some brick, ceramic wall tile, plastic, PVC (maximum cutting depth: 2-3/8-in). Not for use in hammer mode, drilling metal, wood with nails, or block/brick/tile applications with a Mohs hardness of 6 or greater. 18-piece kit contains 12 holes saw bits (3/4, 7/8, 1-1/8, 1-3/8, 1-1/2, 1-3/4, 2, 2-1/2, 2-3/4, 3, 3-5/8, 4-1/8, 4-1/2), four pilot bits (Hex10 TCT, Hex10 HSS, Hex8 TCT, Hex8 HSS), and two arbor adaptors (Hex8 and Hex10) in a hard storage case.
