Chevron drill bits are used for drilling more abrasive formations
like soft sandstones
The Chevron style bit is more durable than the step drill bit but,
because of cutting
structure, will penetrate more slowly.
Rotary table speed should be between 50 and 60 rpm with light to
medium weight on bit
(WOB). Harder formations require more WOB.
