The solid carbide TC620 from Walter Tools
Walter Tools has introduced the solid carbide TC620 Supreme universal thread milling cutter.
The TC620 features internal coolant and a multi-row design that reduces vibration and cutting pressure and enhances dimensional accuracy.
The new thread milling cutters utilize patent-pending Walter DeVibe technology with an anti-vibration land to suppress vibrations and allow higher cutting parameters, while helping boost the level of process reliability and make handling easier thanks to extremely infrequent radius correction. Fast machining time and longer tool life deliver a lower cost per thread, Walter says, while DeVibe improves surface quality, especially with fine threads, regardless of clamping conditions, varying cutting values or the milling strategy.
The multi-row design thread mills are available in UNC, UNF, M and MF threadforms: specifically UNC8-UNC 7/8, UNF10-UNF ¾, M4-M20 and MF4-MF20 with DeVibe offerings starting at 5/16 and 8 mm in each group. These new solid carbide thread milling cutters employ the high performance WB10TJ grade with a specially blended AlTiN coating, allowing maximum performance in many different materials, including difficult-to-machine materials, including under unfavourable conditions, aided by internal coolant that provides reliable chip removal even at high feeds per tooth.
