Qualities of the carbide-tipped HARD-LINE core drills:
Pre-middle rethreading geometry
manufactured with an elaborated pre-middle rethreading geometry
this results in: Low-vibration, smooth and easy chipping at longest durability
Conical spiral
manufactured with a conical spiral
this results in: Proper chip flow and highest chipping power also for difficult materials (heavy duty cutter)
Sandvik carbide teeth
exclusively tipped using Sandvik carbide teeth
we think: Only the best hard metal is just good enough for the Karnasch core drills
Appropriate for core drilling machines:
Metallkraft, Alfra-Rotabest + Alfra Rota-Quick, BDS + BDS Keyless, Bux, Bektop, Euroboor, Evolution, Hougen, Jancy, Magbroach, Magtron, Magnetor, Promag, Rotabroach, Ruko, Universal...
