Far Eastern Drilling takes pride in manufacturing a versatile range of open-bearing, tricone Milled Tooth Bits. Our milled tooth Bits also named steel tooth tricone bit. It is available in a range of formations, such as sandstone, dolomite and granite, as well as softer formations such as shales, clays and red beds. Our specialized tungsten carbide hard-facing helps provide maximum resistance to gauge wear and reduces vibration through harder formations. Thompson's Milled Tooth design will help drillers achieve maximum penetration rates.| Basical Specification | |
