We can offer kinds of self-drilling bits. Like steel cross bits (EX) used for loose to medium dense ground formations. The tungsten carbide cross bits (EXX) used for medium to strong fractured rock formations.

The steel button bits (ES) used for weak cemented soil / sand and weak fractured rock formations. The tungsten carbide button bits (ESS) used for strong fractured rock formations. The steel arch bits (EC) for loose to dense soil or sand formations. The tungsten carbide arch bits (ECC) for medium fractured rock formation. The steel three cutters bits (EY) for weak cemented soil / sand and weak fractured formation. The tungsten carbide three cutters bits (EYY) for medium fractured rock formations.

Self-drilling Anchor nut is used to lock the anchor system. We have hexagonal flat anchor nuts which are designed to transfer the load from the plate into the self-drilling hollow bar. Also have spherical / round anchor nuts are manufactured with a spherical end to compensate for deviations of the borehole angle with respect to the plate surface.
