Contact SupplierWireline Core Drilling is a special type of drilling mostly used for mineral exploration. It is seen that during conventional drilling more time is spent in hoisting and lowering of drill string for taking out the core. With the objective of cutting down the time spent is hosting & lowering of drill string the wireline system was developed.
The wireline core barrel has a retractable inner tube which can be removed with the help of overshot assembly once the 3 mt drilling is completed. The bit, barrel & drillrods need not to be removed to take out the core there by reducing the down time considerably.
The wireline core barrels are made of high strength cold drawn seamless steel tubes and are available in different length. The outer tube of the core barrel is Hard Chrome plated to a length of 18” on both the ends.
Rockdrill manufactures precision machined high quality double tube and triple tube.
