MC80 Concave Spherical Drill Bit
WOOKE HIGH-QUALITY DTH DRILL BITS:
With many years of experience in the manufacturing down-the-hole drilling tools, WOOKE has developed a series of DTH bits that can adapt to various working conditions, widely used in open-pit mining, quarry, and earthwork engineering, water well and geothermal, oil and gas, construction, horizontal directional drilling, and other fields.
The diameter range of the DTH bit covers from 76mm to 305mm, and there is a variety of bit shapes and shanks adapting to the drilling requirements under different working conditions. DTH bit is made of high-quality alloy steel through forging, precision machining, and special surface strengthening technology after heat treatment to improve the service life. The combination of tungsten carbide inserts and the bit was specially developed to meet the drilling requirements which strengthens the rock-breaking ability of the bit.
The DTH bits is the tool cutting rock. WOOKE DTH bits are made of superior quality alloy steel which is made by Timken in U.S. Besides, all our DTH bits are using the brand "Element Six" T.C carbide which provides (the T.C buttons) for Boart Longyear. In addition, art manufacturing technology makes our DTH bits with higher and more reliable quality.
WOOKE BIT HEAD DESIGN AND SELECTION:
Different face style makes DTH bits suitable for various rock conditions.
Flat face: This is a universal design, especially for a hard and abrasive rock formation. So typically, a flat face with the design of a hemispherical button is the most popular choice.
Convex face: A classic design for soft to medium-hard rock formation that is not so abrasive. This design has a very excellent penetration rate but poor hole deviation if rocks are hard.
Concave face: Medium hard to hard rock formations which are less abrasive and fractured. Especially for deep hole drilling, excellent control over hole deviation.
DGR face: A special design for hard or very hard rock conditions, double gauge row buttons provide very excellent ware-resistance and a very long lifetime. It is usually used for some bigger diameter DTH bits.
Besides, we are manufacturing the DTH bits with various shanks so they can be compatible with different DTH hammers.
