Designed for extreme drilling in steels, Guhring’s RT100 XF drill family delivers. The carbide grade developed for the RT100 XF balances hardness and toughness. Polished flutes improve chip evacuation, reducing machining temperature and protecting the cutting edges. The micro-geometry honing process ensures a uniform hone resulting in a stable and efficient cutting edge.

    Grooves and spaces in the body of a tool that permit chip removal from, and cutting-fluid application to, the point of cut.

  • hardness


    Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
