Turning Grades
▶ Excellent surface roughness (2 times higher) at normal feed▶ Shallow depth of cut, excellent surface roughness and high
productivity at high feed (2 times higher than general) and finishing▶ Wiper cutting edge and suitable for high feed design reduce cutting
▶ When you exchange general inserts for wiper insert, please confirm the cutting edge position because wiper insert has different cutting edge position from general insert.
▶ For better surface roughness at high feed machining, please notice that the wiper insert shows better performance at straight machining than at round and taper machining
