M-SIX (MFWN)
How to Mount the Insert 4. Be careful not to tighten the screw with excessive torque. Recommended torque is
4.2N·m for M5 screw (SB-50140TR) and 3.5N·m for M4 screw (SB-40140TRN)
1. Be sure to remove dust and chips from the insert mounting pocket
2. After applying anti-seize compound on portion of taper and thread, attach the screw 5. 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
to the front end of the wrench. While lightly pressing the insert against the constraint constraint surface of the holder. If there is any clearance, remove the insert and mount it
surfaces, put the screw into the hole of the insert and tighten (See Fig. 1) again according to the above steps
3. When tightening the screw, make sure that the wrench is parallel to the screw.
Remember that the screw hole of the holder for Extra Fine pitch is angled to the pocket 6. To index the cutting edge of the insert, turn the insert counterclockwise. (See Fig. 4) The
floor (See Fig. 2 and Fig. 3) insert corner identification number is stamped on the top surface of the insert

How to Replace the Shim
1. Be sure to remove dust and chips from the insert mounting pocket 3. After tightening the screw, make sure that there is no clearance between the shim seat
surface and the pocket floor. If there is any clearance, remove the shim and mount it again
2. The shim must be mounted in the proper direction. While aligning the surface of the shim according to the above steps
with the mark on it to the corresponding constraint surface (see Fig. 1) and lightly pressing
the shim toward the constraint surface of the pocket wall (see Fig. 2), insert the screw into
the hole of the shim and tighten (See Fig. 3). When tightening screw, make sure that the
90 LEADE screw is vertical to the pocket floor (See Fig 3). Recommended torque is 6.0Nm
