Taper Drill Rod With Rubber Collar
The drill rod with rubber collar consists of a tapered drill rod body and a rubber collar. One end features a hexagonal chuck section for torque transmission during drilling, while the other end is tapered for connection to the drill bit.
The rubber collar fits tightly against the conical surface, reducing direct contact between drill rod and drilling rig. This design minimizes wear while reducing noise and vibration during operation.
The product undergoes carburizing heat treatment, hardening both inner and outer surfaces to enhance durability and service life.
