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 — up to 5x faster than standard hole saw arbors. Cut at an angle, and use two adapters (second adapter sold separately) on one pilot bit to enlarge existing holes. All Hex10 Spyder hole saws fit on Spyder Rapid Core Eject™ arbor/pilot bits, or use your favorite hole saw (with a 5/8-18 thread) with the Spyder Rapid Core Eject™ arbor system. Always use a drill motor that is equipped with a support handle.
