In order to optimise the drilling with Wassaras water-powered equipment, we do recommend following the configuration guidelines presented in our Product Selection Guides.
Wassara offers three different Product Selection Guides (PSG).
One is our General guide where you find what you need for most drilling applications. But we also offer a guide for Extra straight drilling and for Casing advancing.
Please feel free to contact us at LKAB Wasssara for recommended configuration of sizes that are not presented here.
