Designed and Made for good cuttings flush off capacity to increase drilling efficiency


Our Tungsten Carbide DTH Drill Bits are made of high quality alloy steel with advanced heat threatment to assure the good drilling performance and long service life. They are widely used by our customers all over the world.The DTH bits have various sizes and styles ,can match many kinds of hammers such as Ingersoll-Rand, Mission, Atlas Copco etc. For the most effective operation in various drilling conditions, we offer flat face, concave, drop centre head designs.


Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application. In most cases, the focus is on productivity, so the fast cuttings removal features (Convex/Ballistic designs) are preferable, to ensure the buttons are cutting clean, with the minimum of recrushing.


In hard and abrasive formations, however, the flat front design offers best bit life, having strong gauge rows with large spherical buttons which are easy to regrind and maintain.Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the requrired hardness, given surfacure compression for fatigue resistence , and fitted with precision buttons manufactured in-house.


DTH bits advantage

1.Material: superior quality alloy steel which is made by Timken in U.S.


2.Tungsten carbide: "Element Six" T.C carbide which provides (the T.C buttons) for Boart Longyear.


3.higher and more reliable quality owing to the high-tech equipment and production technology.

Flat Face

A universal design, especially for a hard and abrasive rock formation. Flat face with hemispherical buttons design is the most popular choice. This kind of face shape is suitable for hard to very hard and abrasive rock formations in application with high air pressure. Good penetration rate and resistance to steel wash.


Dome/Hemispherical Buttons

Universal buttons for all rock formation, best suited to the hardest and very abrasive rock formation.


Semi-Ballistic/Parabolic Buttons

Excellent penetration rate, but only suited to medium-hard and not so very abrasive rock formation.
