The WTX Feed BR drill reamer from CERATIZIT ensures high accuracy with tight tolerances and perfect surface quality. Spot drilling, drilling and reaming to a tolerance of H7 in just one operation? Not a problem for the WTX Feed BR three-edged drill reamer from CERATIZIT. The machining specialist has succeeded in streamlining and improving the manufacturing process further with this newly developed tool.
The key feature of this drilling tool, especially for steel and cast iron machining, is its three effective cutting edges and six guide lands which are responsible for a 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 pure reamer.
The design of the WTX Feed BR solid carbide drill reamer, with three cutting edges, ensures greater contact in the hole, which delivers greater cylindricity and roundness. A considerably tighter tolerance can be maintained for the hole produced, compared to a two-edged drill reamer. These have a rather wobbly penetration behaviour, in contrast the tip geometry of the drill reamer with three cutting edges achieves significantly better centring and positioning.
The geometry of the three cutting edges, which have been taken from the WTX FEED high-feed drill, also open-up applications in long-chipping and soft 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 enjoy shorter machining times with greater tolerances.
The tool is particularly 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 1000 °C.
A drilling test using an 8 mm tool in 42CRMOS4 (H7 hole) at a cutting speed Vc of 55 to 100 m/min resulted in the following: Compared to a version with two cutting edges, the three-edged WTX Feed BR drill reamer achieves a considerably lower deviation, in relation to the diameter, from the hole tolerance. The variance was a maximum of 0.013 mm.
The WTX Feed BR drill reamer can be used for a wide range of product applications from H7 standard applications to diameter graduations in the 0.01 mm range. The tools are available throughout in 3xD and 5xD versions.
