high quality Low Air Pressure CIR110 well drilling rock button bits dth hammer drill bit
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
Advantages:
1.Out of the throuble of foot valve fracture and expansion and contraction.
2.Lower energy consumption and higher impact frequency.The drilling speed is 15%-30% higher than the one with foot valve.
3.Simple structure, reliable parts, long life, easy and cheap maintenance.
Our tools are widelyused in different drilling applications including mining,quarrying, water well drilling, geotechnical industries and etc.

Product Overview
Carbide button shape selection:
1. Domed/Round Button
Domed/Round Buttons are usually used as gauge buttons of DTH Bits, suitable for every abrasive and very hard formations.
2. Parabolic/Semi-Ballistic Buttons
Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.
3. Ballistic Button
Ballistic Buttons are usually used as front buttons of DTH Bits, suitable for medium abrasive and mesium hard formations. They can also be used as gauge buttons if the rock is soft.
4. Sharp Button
Sharp Buttons are usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible.
5. Flat Button
Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
