This bit is the perfect size drill bit for the plugs we sell and most other standard sized plugs. Our plugs and bits are cheaper than most other sellers. This is for one drill bit only.
 
These are approx 8.5mm wide and 25mm deep with a stop collar for perfect depth and speed.  These fit in a drill chuck, and standard a quick attach.
