DTH BIT

With many years of experience in the production and manufacturing of down the hole drilling tools, SHAREATE has developed a series of DTH bits that can adapt to various working conditions.Widely used in open pit mining, quary and earthwork engineering, water well and geothermal, anchorage hole engineering, oil and gas mining, construction pile hole, horizontal directional drilling and many other fields.

PRODUCT OVERVIEW

The diameter range of DTH bit we designed covers from 115mm to 305mm, and there are a variety of bit shape adapting to the dilling requirements under different working conditions. We can produce a variety of DTH bits with shank structure which can match the products of various manufacturers.
The DTH bit itself 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 insert and bit specially developed to meet the diling requirements of various complex formations strengthens the rock-breaking ability of the bit.

BIT FACE SELECTION

Suitable for most rock formations, most effective in the medium-hard and homogeneous rock formations. The face feature helps to reduce deviation and allows good cutting flushing on bit face.

Convex face is suitable for drilling soft-medium hard rock formations under low-medium air pressure. It is deisgned for fast penetration rate in soft-medium ground formation with a good wear profile; but it has less control on hole deviation.

Flat face bits are genral purpose bit suitable for drilling extremely hard and abrasive rocks formation with high air pressure. Flat face bits have good penetration rates and good erosion pattern on bit body.

The drop center face design is best suited to the soft-medium hard formation, and formation with broken layers. The drop center bits have good penetration rate, and low hole deviation.

Double gauge row design is best suited for hard-very hard formation. The double gauge row configuration has good penetration and provides excellent wear resistance.

CARBIDE BUTTON SHAPE SELECTION

Spherical Button

Spherical button is the most common shape used on DTH drill bit. It provides excellent penetration in medium, hard and broken formations, suitable in most types of drilling.

Flat Button

Flat button is used mainly as an additional protection feature on the DTH bit. It is placed on areas where extreme wear occurs to reduce bit body wear in the area.

Ballistic Button

Ballistic button has an very aggressive profile that protrudes out farther than most of the other carbide shapes. This button has the highest penetration rate and rock breaking efficiency, and is mostly used in softer formation.

Ogive Button

Ogive button has a higher aggressive profile that protrudes out farther than spherical button . This button has the higher penetration rateand rock breaking efficiency, and is mostly used in softer formation.
