- Various step and chevron drag bits are available from 2 inch to 17 1/2 inch.
- There is very good feedback because of the quality and price.
- Different drag bits can be made according to your drawings or samples.
They are usually designed for use in soft formations such as sand, clay, or some soft rock.
Their uses include drilling water wells, mining, geothermal, environmental and exploration drilling.
Whenever possible, they should be used to drill pilot holes, for they produce cuttings that are easiest to log.
Usually drag bits are three wings, while sometime people need four wings or five wings.
Other special design is available upon your request.
