Our precision tools for you
Robust diamond hollow drills for professionals. Diamond hollow drills are a specialty of the Günther diamond tools company. All diamond hollow drills are manufactured using the galvanic process and are 100% interspersed with diamonds and are of industrial quality. This has the advantage that the drill can be used longer and its service life is significantly increased. The diamond-tipped drill bits are often used in our diamond drills and drill adapters.
