Our Metric QHC Holders are built for precision coolant delivery in metric tooling setups. Designed to pair with our single point tools, each holder is made from heat-treated steel and features four lock-down screws for maximum rigidity. Precision-placed coolant holes deliver flow directly to the cutting edge, improving chip evacuation and extending tool life. Metric QHC Holders include two flats for stable alignment, and optional backstops are available to enhance repeatability and setup control.
