Product description:

Drag bits also named blade bits, with a TC inserts on the blades.

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.

Advantage

1) Super long life-10 times than cemented carbide drill bits under the same condition. 2) High efficiency-Time of lifting the drilling machine could be reduced sharply, and the average time effciency could be increased more than 2 times 3) Wide range of application-it could have a penetration of rock formation with f≤ 12, especially for the rock formation with f=5-10.
