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.

Our bits are interchangeable with Atlas Copco’s COP32 34 44 54 64 84, Ingersoll-Rand ‘s DHD3.5,DHD3.5HD, DHD 340A , DHD350R, DHD 360, Mission60, DHD380 QL40, QL50 , QL60, QL80.SD10, NUMA100, NUMA120,ect.
Matching the insert to the job requirements is essential in achieving the desired results. Each of the following buttons is ideal for different ground conditions, abrasion levels, PSIs and penetration levels. In general, the larger the number of gauge buttons the better overall performance, especially in hard rock.
