New Ball Nose Insert from LMT-Fette

The WPR-D helical ball nose insert from LMT-Fette was designed in response to problems associated with machining complex contoured workpieces. It uses a helical cutting edge that results in the incremental entry of the cutter and reduces vibration. According to the company’s press release, these cutting edges are always under load for increased stability and further reduced vibration due to penetration. The low and equal cutting forces enable milling operations with greater chipping depth and higher chip removal rates with less wear.
