Anchor bits is used as a sacrificial consumable for drilling hole
SINODRILLS Self Drilling Anchor Bits
Drill bit is the front part of the self-drilling anchor system, by cutting and drilling rocks and other geological structures, the anchor could be sent to the designed depth.
Features
• Different types of bits are offered for different conditions;
• Primary alloy is applied to manufacture the alloy bit.
Applications
Pre-supporting, micropiling for foundation underpinning, slope anchorage, etc.
