11 How to Mount the Inserts 1. Be sure to remove dust and chips from the insert mounting pocket. Fig.1. Apply anti-seize compound on portion of taper and thread of clamp screw. Attach the screw (magnetic head) to the front end of the wrench. While lightly pressing the insert against the pocket walls, put the screw into the hole of the insert and tighten. (ee Fig. 1.) Tighten M screws (B-5TRP) slightly inclined from the insert surface. (ee Fig..) Wrench Clamp crew. When tightening the screw, make sure that the wrench is parallel to the screw. For recommended torque, see Table 1. 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. Fig. θ θ How to Attach Modular Head 1. When clamping the head on the arbor, make sure there is no dust or chips inside (Fig. 1). Do NOT put lubricant on the clamping portion. Fig.1. Attach the head on the arbor and fix it using the wrench (Fig. ). ee Table 1 for Recommended Torque. Note) The wrench is NOT included with product.
