High Pressure DTH Bits


Application:

TheHigh Pressure DTH Bitsare widely applicable to mining industry, tunneling and underground engineering, open pit, construction drill, blast industry, civil engineering operations, road, gas line, pipe and trench projects, quarry work, rock anchoring and ground stabilization projects, water well industry, etc,

Usage:

Type of Buttons:

Semispherical button:

This type button is suitable for very abrasive and very hard rock formations, it’s usually used as gauge buttons of DTH bits.

Ballistic button / Parabolic button:

This type button is suitable for medium abrasive and hard rock formations, it’s usually used as gauge buttons and front buttons of DTH bits.

Conical button:

This type button is suitable for medium abrasive and medium hard formations, it’s usually used as front buttons of DTH bits, If the rock is soft, it can be also used as gauge buttons.

The selection of Bit Face Type:

Drop center face bit:

It has high penetration rates in soft to medium hard and fissured rock formation, and has better hole deviation control.

Concave face bit:

It’s suitable for medium hard and similar rock formations, it has good hole deviation control and good flushing capacity.

Convex face bit:

It has high penetration rates in soft to medium-hard rock formation. It has the best performance of resistance to steel wash, and reduce the load and wear on the gauge buttons, but it has poor hole deviation control.

Flat face bits:

It’s suitable for hard to very hard and abrasive rock formations.
