We stock a wide variety of supreme quality DTH button drill Bits, suited for any sort of drilling application including water wells, quarries, mining, construction, blasting, environmental etc. These button Bits have become a price and performance leader for the drilling industry because of its unbeatable quality, sturdy make, reliability and precision functioning.

Our DTH Button Bits are manufactured from superior quality steel forgings to ensure long life and efficient hole drilling operations. It has been fabricated through numerous machining processes to deliver an immaculate body for high resistance to abrasion and wear and stretch that is normally experienced amid penetrating.

The body of each Bit has been heat treated to require hardness that extends the Bit life for maximum performance in the toughest drilling conditions. They are fitted with high quality imported tungsten carbide buttons to provide optimal drilling experience.

The flushing grooves and holes sustain flushing efficiency for better drilling. The high penetration execution and durability ensure they may handle any test and diverse arrangements of sedimentary rocks like quartzite, marbles, slate and ignite rocks like granites etc.

DTH Bits are available in different sizes and in the diverse standard head face designs (Concave, Convex, and Flat Face), including an alternate mixture of tungsten carbide supplement insert shapes (Dome/Spherical, Ballistic and Parabolic).

Additionally, we offer a comprehensive range of custom-made Drill Bits on an extensive selection of Shanks with a wide assortment of head designs to suit every drilling operation.

Bit Face Shape Selection

Hammer Bits are offered in three basic face designs: Concave, Convex, and Flat Face. Each are designed for specific applications and conditions and for varying rock types and hardness.

Concave is an excellent all-around face design and is used as a general-purpose Bit for most conditions while drilling a very straight hole.
Convex Bits are used for a combination of speed and service life. Having 2 gage rows, they are also suited for hard, abrasive rock.
Flat Face Bits are best suited for broken or fragmented ground and hard formations.

Tungsten Carbide Insert

Design Hammer Bits come equipped with tungsten carbide inserts (buttons), which are offered in three basic designs: Dome/Spherical, Ballistic and Parabolic. You may also request conical or double dome buttons, or a combination of buttons with one type on the face of the Bit and another type on the gauge of the Bit. In addition to button shape options, many Hammer Bit manufacturers offer carbide grade options such as Dynite, DP65, and Diamond Enhanced.

Dome/Spherical Buttons is the most common button design and is used in all applications. Its tough shape makes it durable and best suited for hard abrasive rock and deep hole drilling.
Ballistic Buttons are best suited for less abrasive sedimentary deposits where speed is vital. They are commonly used in Convex face Bits and are less suited to badly broken ground and hard rock.
Parabolic Buttons combine the durability of the Dome/Spherical design and the increased speed of the Ballistic design and are less suited to broken ground.
AF Trading ​​​​​​​​​​​​DTH hammers transmit intensive impact energy with low energy loss. This results in good rock breakage, high penetration rates and high productivity
The equipment is designed to give optimal hole quality, reliability, and long service life, as well as the best blasting results and low total operation cost. DTH Hammers are available in holes sizes from 2 inches to 30 inches.
