Tubing
For stock-form planning, compare round, rectangular, and custom options in our tungsten carbide stock forms guide. To estimate round rod weight from diameter and length, use the carbide rod weight calculation guide.
Choose stock after the tolerance is understood
RO stock can be a practical starting point when the grade and rod size are known. If the part also needs a tight finish or controlled OD after ordering, include the finished tolerance and any downstream grinding requirements with the request.
For round parts that need finished OD control, review CNC cylindrical grinding before treating stock selection as the final step.
*All lengths are standardized
