Type A Drill Collar Slips, often referred to as Woolley Style slips, are essential tools in drilling operations, specifically designed for gripping and suspending drill collars in the rotary table of drilling rigs. These slips ensure secure handling of heavy drill collars, providing the support needed during tripping in and out of the wellbore. Known for their durability and high load capacity, the Type A Drill Collar Slips are widely used in oil and gas drilling.

The Woolley Style design enhances gripping capability and overall safety by distributing the load evenly across the drill collar, preventing slippage and minimizing wear on both the slips and the drill collar. These slips are made from high-grade alloy steel, ensuring longevity and resistance to the demanding conditions of drilling environments.
