Product Description

Product Description

YK brand DTH Hammer

DTH hammmer, combined with DTH drilling rigs and DTH drill bits, is mainly used in engineering construction such as mining, marble, quarry blasting, and water well drilling.

DTH hammer is widely used in geotechnical engineering with various hardness, high hardness hard rocks with equal toughness have the following characteristics:
1. According to different mining conditions, absorb advanced hammer technology at home and abroad, and design
Make new products.
2. Reasonable material selection, advanced manufacturing technology, and perfect quality assurance.
3. Drilling speed is higher.
4. Hardening treatment can be provided to extend the service life and reduce the cost of use.
5. The single impact force is large and the power consumption of the broken stone is low.
6. The piston and weight have excellent power transmission.
7. The structural design adopts modern theory to make the stress wave last longer and the stress amplitude lower values result in longer piston life.

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
