          1. Before inserting the insert into the holder, ensure that there are no foreign
             objects or dirt in the holder slot or slit. Clean using compressed air if
             necessary.

                                                                                                                               Slit

          2. Use the wrench provided to loosen the inner screw to open the tip of the                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           open

             * Ensure that the wrench is firmly in contact with the base of the inner screw
               head when tightening.

CUTTING   3. After the insert has been set in the holder slot, tighten the inner screw while
    DATA     pushing the insert lightly into the pocket as shown in figure 2 to securely
             clamp and locate the insert.
             * Ensure that the wrench is firmly in contact with the base of the inner
               screw head when tightening.

          4. Check there is no gap between the bottom of the insert and holder slot.                                           Fig. 2

             Note) Poor or incorrect clamping of inserts can cause poor drilling performance and/or drill breakage.
                     Therefore ensure that the alignment marks on both the body and insert are aligned when setting.
                     When machining, use safety guards and goggles.
