Soft rock formations consist mainly of sand, clay, limestone or shale and are ideal for drilling with Mill Tooth Tricone bits. When working with soft formations you can use either sealed bearing or open bearing mill tooth tricone bits, depending on the scope and duration of your project. Sealed bearing tricone bits are longer lasting, but generally more expensive due to the precision work required to protect the bearings. Open bearing bits, on the other hand, are not as well protected and will wear out more quickly, however they are cheaper to manufacture. Tricone bits designed for soft rock generally have longer protruding teeth, [A" shaped teeth, or chisel shaped buttons. In all cases the teeth will be more widely spaced for tricone bits that are designed with soft formations in mind.
