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 – 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.
