Griffin graphite rods are sanded and polished to a fine 400 grit finish. The round graphite rods are sanded and polished to a fine finish with a tolerance of .005+/- on the diameter of the rod. The rods are 12″ long and have unfinished ends (not shaped or rounded over). The round stock is made from high grade isostatic tight density graphite. This grade is milled and NOT EXTRUDED like lesser quality import grade stock and will hold a shape better and longer. The high quality will pay for itself by not requiring replacement nearly as often as inferior extruded products. This rod is ” x 1/2″ in diameter by 12″ long”.
