Product Overview
The diameter range of DTH bit we designed covers from 115mm to 305mm, and there are a variety of bit shape adapting to the dilling requirements under different working conditions. We can produce a variety of DTH bits with shank structure which can match the products of various manufacturers.
The DTH bit itself is made of high quality alloy steel through forging, precision machining and special surface strengthening technology after heat treatment to improve the service life.The combination of tungsten carbide insert and bit specially developed to meet the diling requirements of various complex formations strengthens the rock-breaking ability of the bit.

Suitable for most rock formations, most effective in the medium-hard and homogeneous rock formations. The face feature helps to reduce deviation and allows good cutting flushing on bit face. |
Carbide Shape Selections
-
- Spherical Button
-
Spherical button is the most common shape used on DTH drill bit. It provides excellent penetration in medium, hard and broken formations, suitable in most types of drilling.
-
- Ballistic Button
-
Ballistic button has an very aggressive profile that protrudes out farther than most of the other carbide shapes. This button has the highest penetration rate and rock breaking efficiency, and is mostly used in softer formation.
-
- Flat Button
-
Flat button is used mainly as an additional protection feature on the DTH bit. It is placed on areas where extreme wear occurs to reduce bit body wear in the area.
-
- Ogive Button
-
Ogive button has a higher aggressive profile that protrudes out farther than spherical button . This button has the higher penetration rateand rock breaking efficiency, and is mostly used in softer formation.
