Description

Fast bit clamp

This creation is about a fast bit jig.

Press, generally want to lock a screw to an object, when the hardness of the object is too large to directly lock the screw into the object, the drill will be used to drill a hole in the object first, and then the screw is locked in the object Holes, so that the screw can be screwed into the hole smoothly, so the conventional processing method requires the use of a drill bit and a screwdriver bit.

However, such a conventional method is to first loosen the collet of the rotary tool (which can be an electric or pneumatic rotary tool), and then insert the drill into the collet to screw the object, and then rotate. The chuck of the tool unscrews the drill bit, and then takes out the sub-head into the collet and tightens the collet. Then, use the rotary tool to screw the screw at the front end of the screwdriver head to the pre-drilled hole to be screwed tightly.
