Drill bits are often used in construction, and there are many kinds of drill bit classifications. According to the type of drill bit, there are three types of drill bits: three-wing drill bit, anchor drill bit, coring drill bit and non-coring drill bit. Next, let’s learn about coring bits.
What is a coring bit?
Core drilling bits, also called hollow bits, are mainly used for drilling tools for steel plates and other products, hollow bits with special on the core drilling machine, with fast efficiency and low cost, core drilling bits bit edge is made of carbide, with three layers of end tooth geometry, cutting light and fast, long service life of steel plate drill bit, double cutting flat shank interface, carbide bits are also suitable for all kinds of vertical drilling machines, rocker drilling machines, milling machines The carbide bits are also suitable for all kinds of vertical drilling machines, rocker drilling machines, milling machines, lathes, etc.

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
1. 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.
3. Four-hole shank: turn the safety ring on the main shank clockwise into place, insert the shank end directly and rotate it in a small range until the steel ball enters the round hole.
Safety precautions for coring drill operation
