Scope of application of coring drill bit

The drilling performance of the core drilling bit is significantly better than the traditional two-blade twist drill, with high drilling efficiency, light and fast drilling and labor-saving features, the multi-blade steel plate drill and the magnetic drilling machine can be used to drill large workpieces in multiple directions, easy and flexible operation, effectively reducing the construction time. It is convenient and flexible to operate, which effectively shortens the construction time and becomes the preferred tool for drilling modern steel components.

Installation method of core drilling bit

Right-angle shank: align the two planes of the shank end with the two screw holes on the drilling rig spindle, tighten the hexagonal backhand slightly leaving a gap of 0.2-0.3mm, gently transfer the hexagonal screw back and forth by hand to confirm that the hexagonal screw is perpendicular to the two planes, and then tighten the screw with force.

2. Universal shank: If it is a Nitto machine, please put the round hole at the end of the shank into the steel ball in the drill chuck. The universal shank can also be fixed with hexagonal screw, just screw the hexagonal screw vertically on the plane of the shank end.
