One of the key advantages of thread carbide extension rods is their exceptional hardness. Made from a combination of tungsten carbide and cobalt, these rods possess a Rockwell hardness rating of up to 93 HRC, which is significantly higher than conventional steel or aluminum counterparts. This superior hardness allows them to maintain their sharpness and cutting ability even after extended use, reducing the frequency of sharpening and maintenance downtime.
