At present, the application fields of DTH drill bits are relatively broad. DTH drill bits are widely used in coal fields, oil drilling, geological exploration, water conservancy and hydropower, railways and highways, tunnel construction and other industries.

Product advantages

1. Long drill life: Made of alloy steel, it has a long service life and is higher than similar products. High drilling efficiency: the drill teeth are wear-resistant, so that the drill bit can always remain sharp, thus greatly increasing the tooth feeding speed.

2. Stable drilling speed: the drill bit breaks the rock through impact and shearing

3. Good diameter-preserving effect: Yikuang brand drill bits have strong wear resistance and good diameter-preserving performance, allowing the cutting teeth to be efficiently utilized;

4. Wide range of use: Practice has proven that this drill bit is suitable for hard formations such as carbonate rock, limestone, white flat rock, clay rock, siltstone, sandstone, etc. Drilling, compared with ordinary drill bits, especially drilling into 6-8 grade rock formations, the effect is particularly significant

2).If two or more whole carbide buttons completely detach from the button hole with less than 1/4 service life or the drill bit, you can return it to our company for maintenance.
3).We will record the number for the drill bits which should be compensated.If the body is broken or the button is off again, we will not re-compensate it.
4).There is no compensation for broken button, drop piece or broken body of the drill bit if they are caused by improper operation or other human factors or driving reinforced concrete etc.
5). Generally there is no compensation for broken body, drop piece, broken button or
 drop button of the drill bit if the drill bit body and carbide buttons have worn severely.
