Use drilling fluid additives - Reduction of torque leads to longer life of your drilling equipment. Torqueless, an environmentally safe product can be used alone or in combination with other additives to lubricate, reduce wear and rusting of the rods and cool the core bit. It is often used with DD-2000. It also raises the viscosity of the drilling fluids so that cuttings can be more easily flushed out. One added benefit is that it is non-abrasive and helps cool and protect the core bit when mixed with Torqueless, resulting in longer bit life.
Choose the right waterway configuration. You should consider waterway configurations that specifically address the conditions you encounter.
Confirm water flow: Make sure there is proper and sufficient water flow to the bit. Make sure that your rods don’t leak Proper flow and pressure at the bit face will make sure rock cuttings are flushed and the bit is cooled.
