IMAGE Mini Drill Bur, for the drilling the legs at the end of "star breaks", and clearing the entry hole for traditional "bulls-eye" breaks.
If the entry hole is blocked with fragments of glass or general road traffic dirt, it can be impossible to inject the resin into the damaged area.
These mini drill burs have a 1mm drilling tip. There is a shoulder to the drilling tip, which can assist in judging how deep you have drilled into the glass, thereby avoiding puncturing the laminate.
Drill burs fit the chuck of the 12-volt Mini Drill (433079).
