Spyder 600109CF 5-1/2-inch Bi-Metal Hole Saw for Hex10 Arbor

The Spyder 600109CF is a heavy-duty, professional-grade 5-1/2-inch bi-metal hole saw engineered for boring large-diameter openings cleanly and efficiently. Designed with a robust 1-7/8-inch cutting depth and advanced variable tooth pitch geometry, this tool drastically decreases vibration and chatter to provide smooth, rapid cuts through highly dense materials. It is built to integrate natively with Spyder's patented Rapid Core Eject™ (RCE) system, empowering operators to release tightly packed cores instantly with a button press, make clean entries at aggressive angles, and stack a second cup over the pilot bit to seamlessly enlarge pre-existing holes on busy jobsites. Spyder 600109CF 5-1/2-inch Bi-Metal Hole Saw is machined with standard universal 5/8-18 threads to adapt across standard market arbors. It operates at maximum performance when dropped onto the Spyder Hex10 Rapid Core Eject arbor and pilot bit kit.
