DRILLSTAR fishing magnet is a valuable tool before diamond coring or drilling. Its strong magnetic field will retrieve all types of small steel objects from the bottom of the hole. 

Basket subs, also called junk subs, are used during milling operations in order to retrieve the heavy cuttings and prevent them from settling at the bottom of the borehole.

Drillstar Industries washover shoes (also known as rotary shoes or mill shoes) are available in a wide range of dimensions and threads. They come in 12 types, each designed for a specific application.
