Tooling system for turning on multi-task machines HSK-T TOOLS High accuracy cutting HSK-T System edge positioning HSK-T is a new HSK system designed The HSK-T type has a closer tolerance for turning on multi-task machines that between the spindle key and tool holder are compatible with HSK-A type (ISO keyway than the HSK-A type. This standard: ISO12164-1:2001). results in higher cutting edge positional The HSK system was developed accuracies. For milling, the conventional by a consortium of 17 Japanese HSK-A type tools can be still used. manufacturers and registered in ISO standard (ISO12164-3:2008) under the name HSK-T type in 2008 and JIS standard (JIS B6064-3) in 2013.
