Guhring introduces a breakthrough in drilling stainless steels with the RT 100 InoxPro solid carbide drill. This innovation combines carbide, geometry, and a specially tailored coating, resulting in exceptional performance. The drill extends tool life and reduces machining times, addressing challenges posed by stainless steel's high temperatures, tendency to jam, and promotion of tool wear.

Stainless steel's unique properties make it challenging for traditional drills, often leading to tool breakage and reduced performance. Guhring's RT 100 InoxPro, is a solid carbide drill designed for precision in stainless steels and titanium materials. It boasts high cutting values and an extended tool life.

Guhring addresses the challenge of material adherence to cutting edges by incorporating smooth tool surfaces in the RT 100 InoxPro. The drill features polished flutes and a high-quality surface, effectively minimizing built-up edges. This effect is further enhanced by the application of Guhring's Perrox coating, ensuring both smoothness and providing robust wear protection. The optimized geometry of the drill is specifically designed to prevent jamming in stainless steel, resulting in improved wear resistance and overall consistency.

Tests indicate that the RT 100 InoxPro's wear rate is up to three times lower than comparable tools from competitors. Higher feed rates in stainless steel are demonstrated in practical examples, showing a 25% reduction in machining time per component compared to a competitor's drill, while maintaining the same tool life.

  • feed


    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • flutes


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

  • stainless steels

    stainless steels

    Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.

  • wear resistance

    wear resistance

    Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
