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.

The core principle of a pneumatic drilling machine lies in its ability to convert pressurized air into kinetic energy. This is achieved through a complex system of pistons and cylinders, where compressed air is directed into the machine, causing the piston to move rapidly back and forth. This reciprocating motion is then transferred to the drill bit, resulting in a rotary motion that pierces through the surface being drilled.
