■ Caution when installing Notched Insert 1. Install notched inserts by cutting the insert with 2. When installing notched inserts in flute line, the number of marks on the toolholder body. ensure that the number on the insert is the same as the insert in first stage. (Ref. to Fig.1, 2 and 3.) Insert Size 11 Type 17 Type Insert No. 2 3 3 4 Same Flute Line Marks Fig.2 Insert No. * Using the cutter with the inserts installed incorrectly will damage the toolholder.

The recommended cutting conditions above are for notched inserts. 2. If using an insert without notch, the cutting depth (ap) and width (ae) should be less than 60% of those of a notched insert. ・JA Chipbreaker Recommended Insert Grades （Cutting Speed Vc: m/min） Workpiece Material fz (mm/t) Carbide GW25 Aluminum Alloy (Si 13% or less) 0.05~0.3 200~800 Aluminum Alloy (Si 13% and over) 0.05~0.2 200~300 ■ When using inserts with corner-R(rε) 1.6 or larger, additional modifications of the cutter body will be necessary.
