Anchor bits is used as a sacrificial consumable for drilling hole, there usually have Tungsten carbide and steel hardened two types, through machining or casting production technology.
Thread type: R25, R32, R38, R51, T30, T40, T52, T73, T76, T103, T111, T127, T130 etc.

Bits type:
EX: Hardened cross bit for loose to medium dense ground conditions
ES: Hardened button bit for unconsolidated rock with boulders
EC: Hardened arch bit for unconsolidated soil with small boulders
EY: Hardened 3 cutters bit for loose to medium dense ground conditions
EXX: T.C cross bit for soft to medium rock formations
ESS: Button bit with T.C inserts for medium rock formations
ECC: T.C arch bit for soft to medium rock formations
EYY: T.C 3 cutters bit for soft to medium rock formations
Clay bits: Casted clay bit for Soft clay and soil

General guide for anchor bits diameters selection (for reference only):


Anchor Drill tools:
Anchor bolt means a rod that transfers the structures or geotechnical load to a stable rock formations.It consists of rod,coupling,plate,grouting stopper and nut.It has been widely used in tunneling,mining,slope stabilization,tunnel diseases treatment and roof supporting of underground works.It is suitable for loose ground(clay,snad friable etc).Hollow anchor rod is made of seamless tube with high strength.

Epoxy Coating:
Epoxy coating rock bolt is a supporting method with better anti-corrosion effect, which combines hot-dip galvanizing method with epoxy coating method together, which hardens the surface and prevents coating from peeling off.

Applications:
Epoxy coating anchor can be isolated with water and air to prevent the chemical etching and the rusting. So the preservative effect is very well as a permanent support. It is applied to conditions which are influenced by underground water such as road, railway, water conservancy project, sub-sea tunnel, etc.
