Close Tolerance Precision Rolled Rounds
We carry a range of Rounds which can offer attractive cost savings for many machining applications. Material has been produced by the "Kocks Reducing Roll" process and has a close tolerance (typically -0 +.25mm) combined with excellent bar straightness and scale free surface. Size range 22mm - 60mm dia.
For components involving surface removal during processing these products are recommended as a viable cost saving alternative to Drawn Bars.
