Chevron Drill Bits
These are also known as fishtail type bits are a very aggressive, fast digging bit excellent for soft – medium soft formations. Reduce the drilling speed to slow and reduce the weight on the bit to less than half of what you would use when drilling with a tricone drill bit.
A drag bit is a drill bit usually designed for use in soft formations such as sand, clay, or some soft rock. However, they will not work well in coarse gravel or hard rock formations. Uses include drilling water wells, mining, geothermal, environmental and exploration drilling. Whenever possible, they should be used to drill pilot holes because they produce cuttings that are easiest to log.
Drag bits generally are designed for use in softer formations of unconsolidated material such as clays, sands, shale, and soft limestone’s. They have a wide range of uses from geothermal and waterwell drilling to road construction, ground water, natural gas and everything in between.
