Walter TC620 multi-row thread mill

New Walter solid carbide TC620 Supreme universal thread milling cutter, with internal coolant, and a multi-row design delivers greater productivity through design innovations that permit less vibration, reduced cutting pressure and excellent dimensional accuracy.

Watler TC620The TC620 Supreme thread milling cutters utilize patent-pending Walter DeVibe technology with an anti-vibration land to effectively suppress vibrations and allow higher cutting parameters, while contributing to other TC620 Supreme advantages like a high level of process reliability and easy handling due to extremely infrequent radius correction. A low cost per thread is another advantage thanks to fast machining time and longer tool life. DeVibe significantly improves the 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 8mm in each group. These new solid carbide thread milling cutters employ high-performance WB10TJ grade with a specially blended AlTiN coating, allowing maximum performance in many different materials, including difficult-to-machine materials, even under unfavorable conditions, aided by internal coolant that provides reliable chip removal even at high feeds per tooth.
