The 400 Series Tools were developed at the request for the smallest Wireline Sampling System that would collect 3″ Shelby Samples. This Robust sytem includes sampling techniques from soft surface material to hard rock coring. This wireline system is deployed using unique QD Tech 400 Series “Ocean” Drill Rods optimizing remote make and break performance with a light weight internally upset design. The QD Tech Toggle Overshot enables the fixed latch wireline system to work remotely.
