Use this strong metal bar from RS PRO to tool machine parts. It's commonly used in both domestic and commercial settings, including garages, production lines and industrial plants.


As the tool steel bar is fully annealed, it's pliable and easy to work with. It saves you time when machining as it's easy to cut. It's also suited for hardening and has high wear and tear resistance as it's a non-carburised metal. This ensures that the bar will maintain its strength for a long time, even when stretched and reworked repeatedly.


For peace of mind, this tough metal bar complies with British Standard BS 4659: 1971 BO1 as a safe tooling steel. You can use it to make durable cams, gauges and machine parts.
