Nova Spur Centre Chuck Accessory

This is a rugged, 4 pronged Spur Drive with a 19mm square shank which fits snugly into the Nova chuck jaws. This spur center quickly clamps in the Nova chuck, eliminating the need to remove the chuck when requiring a spur center. Creep of the spur is prevented as the shank is slotted to allow the chuck jaws to close over it. The wedged shape of the prongs allows them to penetrate and firmly grip the wood.
