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

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.
Universal buttons for all rock formation, best suited to the
hardest and very abrasive rock formation.
Excellent penetration rate, but only suited to medium-hard and not
so very abrasive rock formation.
