Product Description<\/strong><\/p>\n\n\n\n

We supply slick drill collars<\/strong>, spiral drill collars<\/strong> and non-magnetic drill collars<\/strong>; their sizes are from 3-1\/8 to 11 inches. Besides the drill collars in the table below, we can supply other drill collars at customers’ request.
Materials:<\/strong>  
Drill collars are manufactured from AISI 4145H modified steel, and are supplied in the “as rolled” surface finish condition. Alternative surface finishes are available.  
Rigid Inspection Procedures: <\/strong>
We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar.   
Cold Rolling:  <\/strong>
Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation.
Phosphate-coated or Copper Plating:  <\/strong>
All connections are phosphate-coated or copper plated to improve resistance to corrosion.     
Slip Groove, Elevator Groove and Size:<\/strong>
Lake offers optional slip and elevator recesses to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with API spec 7-1 guidelines.   
Thread Protectors: <\/strong>
Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.<\/p>\n\n\n\n
