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