1. Long service life of the brazing bit: Carbide brazing sheet uses exclusive proprietary technology, strength ≥ 2800N, hardness (HRA) ≥ 92.

2. Pants with continuous trousers: The high-strength tool steel is used for the brazing head body. After a strict heat treatment process, the trouser body has a high strength, so that the trouser body is not broken during drilling.

3. Variety models complete, can meet a variety of different rock hardness level mining.

4. The drilling quality is high.

5. The speed of excavation is quick, no grinding is needed, and the working efficiency is high.

6. Widely used in mines, tunnels, quarries and other engineering projects.
