1. The drilling machine has a small torque when opening holes.
2. Hole opener includes body and tool. Four different types of tools can be assembled on the body in one size to open four sizes of holes.
3, the tool is divided into soft stratum with MT type and hard stratum with TCI type. Huanyu perforator has the advantages of good tooth distribution, good wear resistance, large cutting area and high efficiency.
4. The hole opener adopts internal and external anti-falling device to reduce tool falling accident in harsh drilling environment.
5. Roller bearings and larger sections are used for cutting tools and rubber seals to improve the service life of hole openers.
6. Body guide and support guide parts, surface wear-resistant alloy to improve wear resistance and earthquake resistance.
