The Nova 9020 7/8'' Flexible Point Drive Center features a single spring-loaded center point that engages with the wood first, allowing you to mount your workpiece in the latheâ€”or remove itâ€”while the lathe is still spinning. As you increase tailstock pressure and the outer spur ring bites into the wood, your workpiece will begin to spin. With only light pressure, your workpiece spins, but stops if you have a catch, minimizing damage to your workpiece. Increase the pressure, and the drive center will power through even the heaviest cuts. Since the multiple teeth in the spur ring spread the pressure over a larger area, the center is much less likely to cause splitting than a standard spur drive. Flexible Point Drive Centers are available in a range or sizes to best suit different spindle diameters.Notice: Designed to fit into your Nova 4-jaw chuck (sold separately).
