SINODRILLS Self Drilling Anchor Bit Adapters
As we all know, it will affect drilling performance while too big diameter drill bits connected with smaller sizes anchor bar, so, there need to use a bits adapter to connect between big diameter bits and smaller size anchor bar in anchor drilling jobs. Via the adapter, larger drill bits could be linked to the anchor bar.
Features
• Adapters with various types of thread are offered.
Applications
Pre-supporting, micropiling for foundation underpinning, slope anchorage, etc.
Parameters
| Self drilling Anchor bit adapter is used for connecting smaller threaded hollow bars and bigger threaded drill bits. |
