Rock bit is the most popular one in use. When working, the cogging touch the bottom alternately, breaking torque and the contact area both are small, thus the unit pressure is high, so it can penetrate into the layer easily, the length of the blades is longer, which can reduce the abrasion. The rock bit can adapt to a variety of formations from soft to hand.

Rock Roller Bits:
Soft formation rock bits are used in unconsolidated sands, clays, soft limestones, redbeds and shale. Medium formation bits are used in dolomites, limestones, and hard shale, while hard formation bits are used in hard shale, mudstones, cherty limestones and hard and abrasive formations.
The rock drill bit is connected with the drill rod, through the drive of the rock drill to achieve the purpose of cutting rock parts, the whole system to bear the greatest impact and wear parts. There are different types of rock drill bits, such as chip bits, button bits... Kelleg offers a wide range of rock drill bits, including top hammer bits and DTH drill bits.
Top hammer bit type
1. chisel bit: suitable for light rock drills to drill rock formations with low hardness.
2. Cross bit and X bit: suitable for drilling cracked rock formations and highly abrasive rock formations under the condition of rock drills with large impact power, and have strong radial abrasion resistance.
3. Button bit: Under the condition of a rock drill with a large impact power, it is more suitable than a flaky insert drill bit, has a higher rock drilling speed and service life, and the drilled hole shape is relatively round.
4. Diameter of drill bit:
chisel bits: 32mm-42mm
cross bits: 34mm-65mm
X bits: 55mm-65mm
button bits: 38mm-150mm
DTH drill bit type
1. Including low-pressure DTH drill bits, medium and high-pressure DTH drill bits (high-efficiency and energy-saving types)
2. Nominal diameter:
low-pressure DTH drill bits: 70mm- 250mm

2. Detailed introduction to Bit breaker
1) Bit breaker is mainly used to screw on or off a rock bit to the bottom of drill string.
2) It can also prevent the rock bit from dropping into well hole.
3) The price of it is cheap and the use of it is safety and reliable.
4) It is easy to operate. First, the bit breaker is placed on well hole and then put the rock bit onto it. Turn it to screw on or off the bit by turnplate.
