A pilot bore sprocket is supplied with a small starter bore so it can be machined out to suit the shaft – keyway and set screws. Finer sprockets are made from high quality steel with induction hardened teeth – improving resistance to wear and extending working life. All Finer sprockets are engineered in accordance with ISO 9000 standards.
