Advantages︰ Features
1. Safe, reliable, and time saving. Self drilling system eliminates the requirement for a cased borehole.
2. Simple installation & operation.
3. Choice of drill bits for different ground conditions.
4. Grouting works synchronize with drilling or after drilling. Grout can fill fractures effectively. 
5. Anchor bars can be cut and lengthened on request, applying to narrow spaces.
6. It provides higher bonding stress than smooth steel pipe depending on continuous wave thread.
