New solid carbide end mills from Walter, the Prototyp Supreme TC610 and TC611, are high performace tools that the company says deliver increases in thread quality, milling productivity and process reliability, while boosting tool life.
The TC610 with 1.5xD and the TC611 with 2xD both offer a new geometry that reduces vibration, produces superior surface finishes, as well as a through coolant design that optimizes chip removal and helps prevent fractures.
The real game changers, says Walter, are two new grades. The thread mills are offered in grades WB10RD and WJ30RC. WB10RD, with its exceptional wear resistance, has shown tool life improvements of 40 per cent over other similar thread mills in lab tests. It features TiALN coating with a finishing layer of ZrN. The ZrN layer has a lower affinity for steel, providing lower temperatures in the cutting zone.
The tough WJ30RC grade, with TiALN coating, delivers exceptional process reliability along with improved tool life. It can be run with or without coolant, broadening its areas of application. Importantly, users receive good thread quality from both grades.
The thread mills are suitable for use with ISO material groups P, M, K, N, S, and O, and can be obtained through the Walter GPS system.
