  • Spot Drill Toolholder - 13
    Spot Drill Toolholder - 13
    13 Series

    YIH TROUN indexable spot drill use HSS material and swiss screw to achieve better strength of shank and insert clamping. Patented 390 clamping system improve insert life significantly and more user-friendly in changing inserts. It achieves not only the great center precision but also reduces the time of changing and calibrating the tool. Two different shank designs provides an alternative options when machining in unstable / chattering and interference machining condition.
