The Gaste Glidden #3 in the TFRK (Terauchi File Removal Kit)
If the coronal diameter of the broken file is <0.45 mm or the canal curvature is <15°, use this instrument to enlarge the canal to the broken file.
The pilot tip of the GATE DRILLS #3 is cut off so that the root canal to the broken file can be enlarged to at least 0.45 mm as the tip diameter of the GATE DRILLS #3 is 0.45 mm.
It is used at 2500 rpm, rotating clockwise, with a brushing motion against the outer wall to create a funnel shape.
