Korea –Taegutec has expanded its Mill-Rush line by adding extended flute cutters, also known as “porcupine” or “long-edge” cutters, and splitter inserts to improve performance on roughing operations, the company says.
Extended flute end mills and shell mill cutters are being added to the 3PKT 06, 10, 15 and 19 mm insert line. For tool machining depth, the last two are also added to the Mill-Rush line.
All Mill-Rush inserts can be clamped to extended flute end mills and shell mill cutters. Also, the 3PKT 15 and 19 mm inserts are available with three corners and two grooves, and three corners, three grooves with a different colour periphery, respectively, namely the SM2 and SM3. Both do not miss matches after machining and offer a lower cutting load and less vibration, the company notes.
Furthermore, for the splitter inserts, even number teeth cutters are available as standard items. The inserts are covered with the company’s Gold-Rush coating that is said to offer improved toughness and wear-resistance, and reduced friction to chip-flow while providing workpiece surface finish.
According to Taegutec, the APKT and ANHX splitter insert types can perform under unstable machining conditions such as long overhang or weak fixtures as grooves on the cutting edge reduce the cutting load, vibration and noise. Furthermore, the Mill-Rush porcupine cutter is said to increase metal removal rates and is used for machining rough edges or deep shoulders.
The supplier claims that a case study noted its porcupine cutter with splitter inserts increased tool life by 39% while machining a workpiece made from construction steel. In another case study conducted on cast iron, Taegutec’s extended flute cutter with splitter inserts reportedly outlasted a competitor’s tool by 50%.
