WNT introduces range of enhancements to EcoCut multi-function cutting tool concept

The changes to the indexable insert ranges include the use of WNT's Dragonskin coating and three carbide grades to improve productivity and tool life in a wide range of materials and cutting applications. For general steel and cast iron machining there is the Dragonskin HCR1425 grade, which features an advanced AL2O3-TiN CVD coating to provide excellent wear resistance at elevated cutting speeds. For general steel machining there is the AL2O3-TiN CVD-coated Dragonskin HCR1435 grade, suitable for very tough materials with interrupted cut or less than ideal machining conditions. Finally, there is the Dragonskin HCN2430 universal grade for stainless steel, heat resistant materials, steel and cast iron with its TiALN PVD coating. With higher cutting speeds and feeds now possible, WNT has tackled insert security with the TorxPlus screw system. This improves the transmission of the tightening torque and simplifies handling due to the larger size of the screw. While the insert is often the focus of improvements, WNT has also enhanced the performance of the toolholder itself with the addition of its Highlight coating. This silver coloured, nickel coating reduces friction, reducing abrasive wear on the toolholder and it plays a part in optimising chip flow. Chip flow is also aided by the addition of a backward-facing coolant jet on tools with a 2.5 diameter to length ratio. WNT EcoCut tools are available in three formats: EcoCut Mini, a solid carbide variant of the tool that is capable of machining bores down to 4 mm diameter; EcoCut Classic, a smaller indexable insert version that can machine internal diameters as small as 8 mm; and the larger EcoCut Profile Master range which starts at 10 mm minimum internal diameter and also has a grooving capability.
