WNT launches damped boring bar range


WNT (UK) has announced the arrival of a new range of vibration-damped boring bars with the added benefit of an internal coolant supply. The bars use a combination of a conventional steel body with a pressed carbide core to provide optimum vibration damping.

This combination provides similar performance to that found in solid carbide tools in respect to damping and torsional stiffness, but with a much better price/performance ratio, due to the reduced amount of carbide required. The carbide core is embedded within the steel shaft and the coolant is able to flow around this to exit immediately behind the cutting edge, a feature that further enhances the range’s process security and ability to machine at higher cutting data while generating high quality surface finishes. The range of WNT vibration damped boring bars covers a wide selection of ISO insert styles and bar diameters go from 6 mm through to 32 mm, dependant on which insert style is chosen.

“These vibration damped boring bars are another example of WNT developing products to meet the specific needs of our customers, who were asking for a product that would provide a cost-effective solution to machining small bores with extended diameter to length ratios. By developing the tools with the carbide core, we have achieved what we feel is the optimum price/performance combination, in addition, the use of the steel body provides greater process security when compared to conventional solid carbide boring bars,” says Tony Pennington, Managing Director, WNT (UK).

As part of the standard range of tools on offer from WNT (UK), these vibration-damped boring bars will also be available ex-stock with WNT’s investment in logistics ensuring that customers ordering before 18:30 will be guaranteed delivery next working day, before noon.
