How to find a suitable DTH bit?

DrillMore DTH Drill Bit has a variety of carbide and face designsfor use in different ground conditions.


Spherical/round buttons are usually used as gauge buttons of DTH bits, suitable for very abrasive and very hard formations.	Parabolic buttons are usually used as gauge buttons and front buttons of DTH bits, suitable for medium abrasive and hard formations.	Ballistic buttons are usually used as front buttons of dth bits, suitable for medium abrasive and medium hard formations. They can also be used as gauge buttons if the rock is soft.	Sharp buttons are usually used as front buttons of DTH bits for soft formations, suitable for high rotation speed and low bit broken rate soft rock.	Flat buttons are usually used as protection buttons to reduce wear on rubbing surface of DTH bits.
