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…
