Application

Drill collar is mainly used for providing drill bits with required drilling pressure, ensuring pull force transmitted to drill pipe and centralize the drill bit. According to API Spec7-1 specifications, the material quality is 4145H that’s after heat treatment, thread hardening treatment and phosphate to better anti-seize. It also can be produced upon customers’ requirements.

Characteristics

Heavy Weight Drill collar is an essential part of the performance of Jinke down hole drilling tools. Drill collars provide weight on bit for drilling through formations.

JCDRILL keeps a generous supply of carbon steel drill collars in stock. Lead Collar Lead collars purpose is to put a short amount of space between the drilling bit, and near bit stabilizer. This is just another way Jinke gives you the ability to tweak your performance needs as down hole challenges arise. By adding this short spacing between bit, and near bit stab, you stiffen the BHA wright at the bit, reducing bit walk, therefore, promoting a straighter hole. Jinke keeps a generous supply of carbon steel lead collars in stock.
