About Drillstring Toolbox
A free calculator to find the capacities of drillpipe connections and tubes.
The group behind the DS-1 standard has created this Drillstring Toolbox! It's a free calculator that will tell you what the API-recommended makeup torque is for drill-stem connections with whatever sizes you want to plug in. It'll also give you the tensile capacities of that connection. Swipe to the right and you'll find tensile and torsion capacities for drillpipe tubes, too!
