the ball-toothed-drilling hole series produced. Has a long pass-through period, and its wear-resisting life is about 5-6 times of the grinding life of the same-diameter blade head, which is beneficial to save auxiliary working hours and reduce workers. Physical labor and speed up engineering. Therefore, taper joints and threaded ball joints of different diameters are widely used in various hard and brittle rocks to match rock drilling.

1, the specifications range from 20-diameter diameter 30, diameter 32-diameter 43, diameter 45-60 and so on.

2. Reasonable material selection, excellent manufacturing and quality control in strict accordance with ISO9001 quality management system, not only pay attention to the inherent quality of the product, but also the surface treatment of the product is very fine.

3, design science, beautiful appearance, unique packaging and very eye-catching traceability logo.

4. the product structure is reasonable high, medium and low grade products to meet the needs of different customers. the alloy classification is applicable to rocks with different hardness coefficients.

5, the courage to innovate, continuous improvement and continuous introduction of patented products ---- "high-speed word-head" and "fine billet bit" to fill the gap in the industry.

6, the sales channels are smooth, the service network is sound and the sales outlets are all over the country, the supply is timely, and the service is perfect. 7. Big brands, trustworthy production and sales rank first in the same industry
