Diameter: The outside diameter of a Short Drill Collar is 3 1/2, 4 1/2, and 5 inches. The inside diameter can also vary but is usually much smaller than the outside diameter.
Length: As the name suggests, Short Drill Collars are shorter than regular drill collars. They can range in length from 5 to 10 feet, depending on the application.
Material: Short Drill Collars are made of high-strength alloy steel, designed to withstand the intense pressures and stresses of drilling operations.
Connections: Short Drill Collars usually have API connections, which allow them to be screwed into the drill string.
Weight: The weight of a Short Drill Collar can vary greatly depending on its size and material, but it is generally heavy enough to provide significant weight on the drill bit.
Slip and elevator recesses: These are grooves cut into the collar to allow for secure gripping by the handling tools.
