CAM

CAM 2653 2276 33 Located within the drifter's rotation unit, this cam plays a direct role in turning the drill steel. It translates motion from the drifter's internal mechanics into the precise, incremental rotation needed to break rock effectively. Without proper cam function, the drill bit fails to strike a new rock face with each blow, drastically slowing down penetration speed.

A worn or damaged cam is a common cause of poor drilling performance. It leads to erratic or weak rotation, which not only reduces efficiency but also increases the risk of the drill string getting jammed in the hole. This puts unnecessary stress on other rotation components, potentially leading to more widespread and costly failures inside the drifter.

Listen for clicking or grinding sounds from the drifter, and watch for inconsistent rotation of the drill chuck. These are clear signs that the cam may be worn. During a drifter rebuild, always inspect the cam surfaces for rounding or pitting and replace it to restore reliable drilling performance.
