NBK (Nabeya Bi-Tech Company) Recessed Damaged Screw Removal Bit , Impact Screwdriver Set

By crushing or licking the recess, it is a tool that can remove machine screws with cross holes and bolts with hexagon holes that cannot be removed with ordinary tools.
Make a groove in the damaged recess with the dedicated bit [[SKEIB]], use the groove, and remove it by turning the screw. For details, refer to "Screw removal work method".
Use a combination of a dedicated bit [[SKEIB]] for creating a groove and an impact driver [[SKEID]] for turning the screw in the direction of loosening by impact.
You can also remove countersunk screws whose heads cannot be grasped with a tool such as a spanner, and screws attached to counterbore holes.
It is applied to two types of recesses, hexagonal holes and cross holes.
[[SKEIB]] -------- For hexagonal holes
[[SKEIB-SPH]] [[SKEIB-MPH]] ---- For cross holes
[[SKEIB]] [[SKEIB-SPH]] [[SKEIB-MPH]] [[SKEID]] can be purchased separately.
For removing screws that cannot be removed with ordinary tools due to damage to the recess
* Do not use for anything other than removing screws with damaged recesses.
* Please use [[SKEIB]] in combination with [[SKEID]].
* Use a bit suitable for screw recess.
* Do not use [[SKEIB-SPH]] [[SKEIB-MPH]] for screws with high surface hardness due to heat treatment. The bit may be corrupted.
* When hitting with a hammer, the impact is also transmitted to the part where the screw is attached. The impact may be absorbed and no groove may be created, or the mounting location may be damaged.
* Do not use for screws with low recess strength such as resin screws, as the screws may be further damaged.
* Do not hit with excessive force as the broken state of the screw may worsen or the bit may be damaged.
* The tip of [[SKEIB]] is sharp, so be careful not to touch it and injure yourself.
* When hitting with a hammer, be careful not to accidentally hit your hand or finger.
* Because it is made of metal, do not use it in an energized area.
* Please wear protective goggles when working.
