Revolutionary 4-flute geometry
The specially developed 4 flutes combined with extremely irregular pitching make the ADVACEDLINE PRO® countersink a universal jack of all trades.
With diameters ranging from Ø 10.4mm to a maximum of Ø 40.0mm, it guarantees optimum countersinking results in stationary applications and with hand-operated drills.
Combined with our special TIN and TIALN multilayer coatings, high-performance machining results are not a problem, even with demanding steels such as Hardox.
