How to mount an insert

Fig. 1 Wrench 1. Be sure to remove dust and chips from the insert mounting pocket. Clamp screw 2. Clamp screw 1. Apply anti-seize compound on portion of taper and thread of clamp screw. 2. Attach the screw to the front end of the wrench. While lightly pressing the insert against

the constraint surfaces, put the screw into the hole of the insert and tighten. (Ref. to Fig. 1)Fig. 2Purple grip
3. Wrenches and clamp screws are "Torx Plus".
1.Fig. 2 wrench is for MRW-12. (Straight grip)Detail of shape
2.Fig. 3 wrench is for MRW-16. (T-shaped grip)The symbol means "Torx plus".
Straight grip wrench for MRW-12
Please use a "Torx Plus" Wrench for tightening cramp screw.
* If a "Torx" wrench (Fig. 4) is used to tighten, the screw head might become damaged and
then the screw cannot be removed.Fig. 3Purple grip

4. When tightening the screw, make sure that the wrench is parallel to the screw. Recommended Tightening torque, See spare parts table. Detail of shape 5. After tightening the screw, make sure that there is no clearance between the insert seat surface and The symbol means "Torx Plus".
