Guhring RT 100 HF reliability and stability in Inconel

With the new Ratio drill type RT 100 Guhring is presenting a newly developed solid carbide drill at AMB 2012 in Stuttgart that sets new standards regarding process reliability and performance especially for the machining of difficult-to-machine materials.

The new RT 100 HF is optimally suited for the machining of high-tensile materials and nickel-based super-alloys as for example Inconel 718.

With its robust cutting edge geometry it is optimised for the typical wear types of high-tensile materials and nickel-based alloys. In addition, the new geometry results in a reduced thermal loading of the cutting edges. The Guhring specially developed, extremely hard Signum coating offers a highly effective wear protection for the machining of these difficult-to-machine materials thanks to its high hot wear resistance and its high diffusion resistance.

A thermo-graphic examination shows that the heat stresses at the cutting edge of RT 100 HF on the right are clearly lower compared to the conventional cutting edge geometry.

The new drill type enables extremely economical machining of heat and chemical resistant materials. It supplements the Guhring product range for applications in the aerospace industry, the energy plant engineering industry, the chemical industry and increasingly also in the automotive industry, that all benefit from the constructive advantages of these difficult-to-machine materials.

The RT 100 HF is available as a standard tool for drilling depths 3xD, 5xD and 7xD with internal cooling as well as without for the drilling depth 3xD. Furthermore, Guhring manufactures special tools in intermediate dimensions or with steps according to specific customer requirements.
