    ● Double-edged cutting, fully ground insert for improving machining stability. No offset.
    ● Center coolant / Pre-balanced G6.3, 10,000 r.p.m.
    ● Ergo integrated ER taper-shank cutter is design to apply on live spindle tool of turning center and Swiss type lathes. And also good for tapping and machining centers.
