Spyder’s Bi-Metal hole saws feature variable tooth pitch geometry and bi-metal steel that make them the durable choice for making holes in wood with nails, metals and plastics. Use 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 use two adapters (second adapter sold separately) on one pilot bit to enlarge existing holes. All Spyder hole saws fit on Spyder Rapid Core Eject™ arbor/pilot bits, and on universal hole saw arbors.
