Ball-nose / radius type cutters MRW 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 Fig. 2 Purple grip the constraint surfaces, put the screw into the hole of the insert and tighten. (Ref. to Fig. 1) 3. Wrenches and clamp screws are "Torx Plus". 1. Fig. 2 wrench is for MRW-12. (Straight grip) Detail of shape The symbol means "Torx plus". 2. Fig. 3 wrench is for MRW-16. (T-shaped grip) 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. 3 Purple 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". the bearing surface of the toolholder or between the insert side surfaces and the constraint surface T-shaped grip wrench for MRW-16 of the toolholder. If there is any clearance, remove the insert and mount it again according to the above steps. Fig. 4 Blacck ggrip T15 DetDaiel toafilshoaf psehape TThhee symbboollmmeeaannss "Torrxx"".
