Vole Brand Tufnol
Vole Brand Tufnol is a medium / fine weave grade suitable for mechanical applications where the finish requirements or shape of the component require a finer reinforcement than other general purpose grades. Vole Brand Tufnol is excellent for screw threading and other parts where good machining is required.
Applications:
A wide range of mechanical applications where a good machined finish is important such as fine gears, threaded items, scraper blades and wear resistant components.
