How to Mount Insert Wrench
Clamp Screw
1. Be sure to remove dust and chips from the insert mounting pocket. Fig. 1
2. Apply anti-seize compound on portion of taper and thread of clamp screw.
(1) Attach the screw (magnetic head) to the front end of the wrench.
(2) While lightly pressing the insert against the pocket walls,
put the screw into the hole of the insert and tighten. (Ref. to Fig. 1.)
Tighten M3 screws (SB-3065TRP) slightly inclined from the insert.
(Ref. to Fig. 2.) surface of the insert.
3. When tightening the screw, make sure that the wrench is parallel to the screw. For recommended torque, Ref. to E6
4. After tightening the screw, make sure that there is no clearance between the insert seat surface and the pocket floor of
the holder or between the insert side surfaces and the pocket walls of the holder. If there is any clearance, remove the
insert and mount it again according to the above steps.
