Product Description

Product Description

DTH drill bits can be used in the following applications

* GW - geothermal bore holes and water wells.


* Construction industry - Piling, footings, soil nailing.

* RAB - rotary air blast - mineral exploration using a conventional DTH hammer.

* RC- mineral exploration and pit grade control (needs specialized reversed circulation hammers).

* Mining- drill and blast holes in open pit mining, where the drill operator will drill several holes, then fill with explosives and        detonate to lift rock allowing access to ore body.


* Oil and Gas - Deep well bore holes: air hammers can be used as long as cutting uplift and borehole stability are ensured.         For deeper wells, new DTH technologies including water hammer and mud hammer can be used to improve drilling rates in     hard rocks.

-Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
