Anti
Stick-slip
Tool
The Anti Stick-slip Tool (AST) from Tomax ensures stable loading of PDC bits in all kinds of rock. This allows the cutters to cross boundaries with minimal waste of energy and low risk from vibrations.
Autonomous regulation of the drill-bit interface has proven useful for drillers aiming for continuous improvement of operational efficiency.
The millisecond response of the AST reduces losses to friction at the rock interface. This leaves more energy available to cut rock faster and at the same time reduces cutter heat and, consequently, wear.
