Turning
        ISCAR has developed a new concept for high
        pressure coolant supply for VDI DIN 69880 quick-
        change adaptation systems, intended for turning
        machine tools. The JETCUT concept is based on
        bottom-fed high pressure coolant channels and
        provides coolant supply internally through the tool and
        externally through the flange.

        A wet coolant can act as an excellent tool in a radically
        different field: increasing the rotational speed of a
        tool. ISCAR’s SPINJET family of coolant-driven high
        speed compact spindles for small diameter tools helps
        upgrade existing machines to high speed performers.
        The SPINJET spindles are recommended for tools
        up to 7 mm (.275 in) in diameter; however the optimal
        diameter range is 0.5-4 mm (.020-.157 in). Depending
        on pressure and coolant flow rate, the spindles
        maintain a rotational speed of up to 55000 rpm.

                                                               central axes of a reamer and a hole. Precise alignment
