A 3-in-1 cup bur finishes and rounds prongs during stone setting, clearing metal shavings as it works so the tip comes out clean and controlled.
Busch Fig. 411T cup burs pair the traditional concave cup shape with twincut blade geometry for exactly that job. They are manufactured from tungsten vanadium steel to ultra-high precision tolerances and are sold here in packs of six, in 13 sizes from 0.80 mm–2.00 mm.
