The WTX Feed BR drill reamer from Ceratizit ensures high accuracy with tight tolerances and excellent surface quality. Spot drilling, drilling and reaming to H7 tolerances is all in a day’s work for the WTX three-edged drill reamer. Ceratizit has succeeded in streamlining and improving the manufacturing process further with this newly developed tool. The key feature of the tool, especially for steel and cast iron machining, is its three effective cutting edges and six guide lands which are responsible for significantly shorter cycle times, high accuracy and surface quality. In a nutshell, the WTX Feed BR is ideal for all machine operators who require extremely high quality holes, but do not need the level of precision that can only be achieved with a conventional reamer. The design of the WTX ensures greater contact in the hole which delivers better cylindricity and roundness – and when compared to a two-edged drill reamer, tighter tolerances can be maintained with more positive centring and positioning through superior tip geometry. The geometry of the three cutting edges, which have been taken from the WTX Feed high-feed drill, also opens up applications in long-chipping and softer materials, which was previously only possible to a limited extent with the two-edged version. WTX Feed BR also achieves higher cutting values so users can benefit from shorter cycle times. The tool is highly wear-resistant thanks to its proven DPX14S Dragonskin coating. This is a TiAlN nanolayer coating with a coefficient of friction (dry against steel) of just 0.35. It is stable up to a maximum application temperature of 1,000°C. A drilling trial using an 8mm tool in 42CRMOS4 (H7 hole) at a cutting speed Vc of 55 to 100m/minute resulted in the following: compared to the two cutting edge version, the three-edged WTX Feed BR drill reamer achieved a considerably lower deviation, in relation to the diameter, from the hole tolerance. The variance was a maximum of 0.013mm. The new drill reamer can be used for a wide range of product applications from H7 standard applications to diameter graduations in the 0.01mm range. The tools are available throughout in 3xD and 5xD versions.
