Tungaloy Announces Expansion of Grade AH9130 to DMP Drill Head Line

Iwaki, April 2020 — Tungaloy is expanding its AH9130 drill head grade series to include the DMP drill head line of the DrillMeister head-changeable drill series.

DrillMeister features a unique self-locking interface that interlocks between the drill head and tool body, enabling a simple and quick tool exchange. Operators can replace the tool without having to remove the drill body from the adapter or re-measure tool offset values, thus saving a great amount of tool setup time.

This AH9130 grade expansion encompasses the DMP line of general-purpose drilling, succeeding the popular DMC drill head for precision drilling. Developed for drilling applications, AH9130 is a nano-multilayer PVD coating consisting of three distinctive layers. This coating configuration adds multifunctional characteristics to the grade, including wear, fracture, and oxidation resistances, as well as eliminating build-up edge and delamination, providing all characteristics required for the grade to enable long and predictable tool life in drilling operations.
